Abstract
This site is located 60 km southwest of Khalkhal, in Shahrood plane, in Khalkhal city and 180 km south of Ardabil city. In May 2006, during the implementation of the road construction project in Khanghah village, the remains of several graves were revealed. From this date onwards, four seasons of Archaeological studies were conducted on this site. The first season was carried out in the same year, and graves 12, 19 and 25 were explored, among them a grave to the Iron Age I and the other graves belonged to the Iron Age II. The trench B was also explored in order to identify of more tombs. Following the excavation, graves 14, 15, 16, 18, 19, 20, 21, 22 and 24 were discovered in this trench. According to studies on these graves, 2 graves belonged to the middle Bronze Age, 1 grave to the Iron Age I, 9 graves to the Iron Age II, and 4 graves belonged to the Parthian period. The second season was explored in 2007. In this season, the trench C with dimensions 10 x 10 m on the west side of the trench A and trench D with dimensions of 5 × 5 m along the trench B was explored. As a result, in this season, the remains of the 5 ancient graves were obtained; one of them belonged to the Parthian period, 1 grave to the Middle Bronze Age and three other graves to the Iron Age I. Four scientific explorations have been conducted in which the results of the first season are fully published. In this study, the graves of the Iron Age of the second season of this site are discussed. The comparisons, such as the results of the grave studies of the first season of the cemetery, show a cultural connection with the mid and late bronze Age sites and the Iron Age I and II, indicating a cultural sequence from the Middle Bronze Age to the late Iron Age II, which contrasts with the theory of cultural dynamism. So, the main hypothesis of this study, it is: Theory of cultural dynamism in Iron Age I, in this area isn’t correct.

Introduction
Gilavan cemetery is located northwest of Khanghah village and adjoined to it. In terms of archaeological findings, this cemetery is one of the most prominent sites in the north-west of Iran, because of the burial of the three archaeological periods of the middle Ages, the Iron Age and the Parthian period. Four scientific explorations have been conducted in which the results of the first season are fully published. In this study, the graves of the Iron Age of the second season of this site are discussed. During this season, 5 ancient graves were explored, identified by numbers 26, 27, 28, 29 and 31. Grave No. 29 dated to the middle bronze age, graves 26, 28, and 31 dates to the Iron Age I and 27 to the Parthian period. The graves of this cemetery were in the form of a hole in which burials were carried out in single and double burials. In the present study, gravels of the Iron Age of second season were qualitatively, descriptively-analytic and comparative approach, and compared with the effects of other burial grounds of the north-west and neighboring areas. The comparisons, such as the results of the grave studies of the first season of the cemetery, show a cultural connection with the mid and late bronze Age sites and the Iron Age I and II, indicating a cultural sequence from the Middle Bronze Age to the late Iron Age II, which contrasts with the theory of cultural dynamism. The studies of Gilavan cemetery are important because in this area, in the burial findings of the graves, we witness a cultural sequence from the middle Bronze Age to the Iron Age II. Such results are of particular importance to the studies of the Iron Age, as well as the theory of cultural dynamism in the late period of the Bronze Age and the Iron Age, which some researchers believe it to be.

The tombs of Gilavan cemetery in this study
Tomb No. 26: This tomb is located in trench D, and in the northeast it, in a depth of -107 cm from bench mark. This tomb is from type of grave pit that after the burial from the rock has been used to highlighting the grave. This tomb has been belongs to man25 to 30 years old.
Tomb No. 28: This tomb is located in northwest corner of trench C, and highest level this tomb from the ground -149 cm. This tomb is from type of grave pit, and single burial. Tomb No. 28 has been belongs to female 25 to 30 years old. 
Tomb No. 31: This tomb is located in the northern part of trench C, and to form of double burial. Tomb No. 31 is from type of grave pit. 

Conclusion
The study of the graves of the Iron Age of this site indicates that there are many similarities in the burial findings of the northern-western areas of Iran during the bronze and iron period. In other words, the findings of this cemetery can be compared with the burial objects of many sites of the middle bronze, the late bronze and Iron Age I and II, and this represents a cultural sequence during a period to a period Another is in the north-west of Iran and even neighboring areas. It seems that many of the developments in the Iron Age region of Iran are rooted in the earlier period. Many of the forms and techniques of constructing objects represent a kind of evolved designs, and the subject matter that implies the emergence or sudden appearance of them is not visible.

Abstract
Waqf is one of the oldest and most valuable human heritages that has been widely used among all ethnic groups, religions and civilized nations of the world and in different periods of Iranian history and has had lasting effects on societies. The issue of waqf and its formation and function have had a long history in the city of Ardabil. The city of Ardabil has had strategic and geopolitical value in terms of geographical location. During the Qajar period, although Ardabil did not have the prosperity and glory of the Safavid period, but people, especially Shiites, paid much attention to that city and until the end of the Qajar period, they went to visit the tomb of Sheikh Safi. The religious nature of Ardabil, especially as the origin of the head of the Safavid sect of Sheikh Safi al-Din and the location of his tomb, has had a great impact on the role and function of the waqf tradition in various religious, cultural, social and economic dimensions. The present study was done in a descriptive-analytical manner. To this end, libraries and archival documents and Waqfnameh were studied, reviewed and analyzed in the General Directorate of waqf and Charitable Affairs of Ardabil province. The present study seeks to answer the question: what socio-economic functions did the tradition and institution of waqf have in Ardabil during the Qajar period and what were the amount, types and uses of waqf in Ardabil? The analysis revealed how the socio-economic functions of waqf have been influenced by socio-historical events and intellectual currents of the Qajar period. Due to the religious nature of Ardabil, religious waqfs are the most common items in Waqfnameh. In addition, waqfs have been given to those people who have actually needed them. Also, new intellectual movements and the familiarity of Ardabili waqf doers with new ideas, including constitutionalism, have had a significant impact on the types of waqfs.

Introduction
The institution of endowment as an institution rooted in the history of Iran dates back to before Islam (Ahmadi, 43:1391). In the ancient period, Iranians paid attention to following their religion and doing good deeds and especially taking care of the poor in the society and to maintain the fire temple. have had offerings and endowments (Salimi Far 1370: 52). Waqf literally means imprisonment. Current charity is usually interpreted as endowment. Waqf is defined in Shari’i terms as confiscation of principle and surrender of benefit (Obeid Al-Kabisi, 1995: 64, Office of Scientific Cooperation and Elite Affairs.... 2015: 39, Qurashi, 1996: 236). What is meant by “confinement of the object” is actually separating the endowment from the property of the waqif and keeping the object from transfer, and the owner will no longer have any rights to that property (Saadat Mostafavi and Sedghi, 1393: 67). The economic definition of endowment can be considered as a change in the use of resources from individual exploitation to social benefit for the present and future generations (Mesbahi Moghadam et al., 2010: 99).
Awqaf played a very important role in the life of the cities and it spread so much that a special court was established for it, which is known as “Diwan of Ihbas” or “Diwan of Awqaf” (Abdul Sattar Osmani, 1376: 83). In the turbulent years between the extinction of the Safavid dynasty and the establishment of the Qajar dynasty, many properties were either taken over by the government or turned into private properties (Lambton, 1363: 128-124). In the traditional Qajar system, most of the civil institutions, even if the people involved in the government were the founders, functioned in the form of endowment and relied on a stable endowment system.
Question and Hypothesis: Considering the importance of endowment documents and the lack of attention to them, the present research seeks to answer this question: What process did the tradition and institution of endowment in Ardabil go through after the establishment of the Qajar period and the religious, social and economic functions of this institution within the scope of What were the developments during the period under investigation and what was the impact of current intellectual currents on endowments?
It seems that the functions of the endowment were influenced by social-historical events and intellectual currents of the Qajar period, especially the constitutionalism movement. With the spread of new knowledge and the intellectual transformation of the society, endowments in a new style were created, and this process was created in the constitutional period by creating endowments such as the endowment of a bath, the endowment of land for the construction ، expenses for the needy patients, and the establishment of schools in a new style and... new dimensions and It is applicable.
Research Documents: In this article, 84 dedication letters have been studied and analyzed The endowment letters were obtained from the document center of the General Department of Endowments and Charitable Affairs in Ardabil province, exclusively in Ardabil city, and their file numbers will be mentioned in the references. In the following, the endowment letters will be discussed and analyzed based on issues such as religious, economic, social functions, the gender of the waqfs, trustees, and the social status of the waqfs.

Analysis of Endowment Documents based on the Gender of the Benefactors
Explaining the role and social status of Ardabil women in the endowments of the Qajar era because it refers to the explanation of the presence of women in various political and social arenas in the Qajar and Pahlavi eras, which is important. Among the studied waqf letters, there are 11 waqf letters related to the waqf by Ardabil women According to Table 4, from the beginning of the Qajar period to the 1960s, we can see the expansion of the presence of women donors among the studied samples. It seems that in the process of the constitutional process, Iranian women also try to achieve their natural and social rights and engage in a wise and wide-ranging struggle in many ways and emphasize the realization of their demands in the social, cultural and political fields (Afari, 1377: 5). The process of describing women in the studied area has a forward tone, in accordance with the general trend of the country, and it indicates that the tradition of women’s endowments is gaining ground under the influence of the prevailing political, cultural and religious currents. Perhaps another reason for favoring and paying attention to endowment among women is related to the new political, social and cultural reasoning of Iranian society in the era of constitutionalism against the tradition and modernity of government and society and citizenship rights, and it has brought individual freedom for women. (Ajdani, 1386:7). In the deed of endowment on May 2, 1346, (file number: 3), a woman gives half of her dowry to her husband and donates the other half to a mosque in Ardabil. Ardabili women have given endowments such as agricultural land, land, house, yard, shop, village and residential building in numerous letters of endowment. The place where these endowments are spent is for building, repairing and spending the mosque, giving prayers, charity, and the expenses of the imam of the congregation, etc. In the deed of endowment on 20 Jumadi al-Thani 1326 AH, Khursheed bequeaths the profits from her endowment from the village of khoshkehRood (with a compromise with her niece) in Ardabil to be spent on charity and charity of Hazrat Seyyed al-Shahada, peace be upon him (file number: 1/ x) The proceeds from the waqf nameh of Jumadi al-Thani 1334 AH, Maryam the daughter of Muhammad Qoli, who owns a shop, should be spent on Imam Hossein’s funeral (case number: 16). In her letter of endowment dated 25 Jumadi al-Awwal 1341 A.H., Ruqiyeh Khanum Dokhtar Marhamat has assigned the income from her shops and residential building to carry her husband’s and daughter’s body to the highest honors (file number: 5/R).

Conclusion
Waqf is good and a valuable heritage with various religious, social and economic aspects, and the remaining waqf nameh are like valuable documents in order to explain the process and social system of their time. The importance of examining the dedication letters of the city of Ardabil, on the one hand, in terms of the social situation (the nature of Ardabil’s relationship with the Caucasus and the role of its market in the commercial relations of the region in the last century) has strategic value and political geography, and on the other hand, in terms of the role of Azerbaijan in the current of thought. Constitutionalism is very important as the center of the most important developments of the Qajar era at the macro level, this article explains the impact of the intellectual currents of an era on the cultural and social manifestations crystallized in the documents, and at the micro level, the results of this research showed that the new intellectual currents and the familiarity of endowments Ardabili with new ideas, including constitutionalism, have an impact on the type of endowments. It has made significant contributions, among them the expansion of endowments among women, the construction of hospitals, baths, and schools are among the clear examples of this issue. In other words, at the threshold of the society’s familiarity with new knowledge and the intellectual developments of the society, endowments in a new style were created, and this process was created in the constitutional period by creating endowments such as: endowment of the bath, endowment of land for the construction of the bath, expenses for the needy patients and the establishment of schools to New style, etc finds a new and practical dimension the impact of new ideas and new health teachings on endowment can be seen by comparing these two timelines In the waqf nameh of 3 Muharram 1286 AH, the type of reception in the ritual ceremony on Thursdays is specified as tea, coffee and hookah (file number: 10/). In case, in the deed of endowment on 8 Dhul-Qaida 1332 lunar year, the donor has bequeathed all the objects and tools, except for the Sarqalians, to be used in ta’ziyeh and benevolence of Hazrat Seyyed al-Shoheda (case number: 5/k). In fact, it can be seen that in the Qajar period, due to the increasing influence of religious beliefs and beliefs in the society, the neediness and poverty of the people of Ardabil due to the occurrence of natural and social events and crises, as well as the new intellectual currents of various people from guilds, owners and From businessmen to ordinary people, social endowments have been placed alongside religious endowments as a priority. Throughout history, religious figures have taken the majority of donors and endowment affairs and had a special place in this matter, but after the beginning of the constitution and the beginning of the new century, family responsibilities and especially trust in the classes and personalities Social has prospered more than before Examining the social status of the donors shows that merchants and tradesmen account for the most frequency. In general, it should be acknowledged that somehow all benefactors were part of the business and market class it is interesting to pay attention to the expansion of the culture of endowment by Ardabil women after the intellectual currents after the constitutionalism, which seems that in the process of the constitutional current, women appear more and more in social arenas to achieve their natural and social in terms of the social status of the benefactors, who were generally from the merchant class, the endowment of commercial buildings is the second most abundant after real estate and farms. It should also be added that in addition to these mentioned cases, endowment in the field of health, treatment, drinking water, as well as in the field of education in the process of time and in terms of social issues, gradually occupies a larger part of endowments.

Abstract
Glaze is a prepared mixture of materials ready for application to ceramic wares by dipping or spraying. In Islamic period, decoration using the glaze was widespread. Different methods of glazing have played a major role in the beauty of glazed potteries during this period. Turquoise glazed potteries are one the significant groups of Islamic period. In this article, five turquoise glazed pottery sherds have been studied in order to identify their elements, composition and technology. The mentioned sherds dated back to 14 - 18 A.D (late Ilkhanate, Timurid and Safavid periods) , and identified from a historical house called Moravvej-e Ardabili House, in the historical part of Ardabil city. This site identified in a rescue excavation held by HassanYousefi which regarding to the cultural materials dated back to 11 - 18 A.D. The aim of this article is investigating and understanding the similarities and differences in five glazed sherds. Regarding to the mentioned point, XRD analyze applied for characterizing their phases as well as EDX analyze used for identifying the elements of glaze, and also their quantity. This research has an analytical approach and it’s method is based on analytical studies, textual evidences and comparative analyzes. According to the results obtained from analyzes, four glazes have an alkaline based and one has a lead base. Colorant oxides in glazes represent that copper used as the primary element to make the turquoise color. In general, the main elements in glazes include silica, aluminum, calcium, sodium, potassium and a negligible amount of lead. Statistical analyzes represent that the most similarities exist in sample two and sample five which belongs to the same period (late Ilkhanate and Timurid),and the most differences exist in sample four and sample five which dated back to a different periods.

Introduction
In the prehistoric era, slip used as a sort of glaze in order to proof the body of the pottery, increase the aesthetical aspect of the pottery and protect the hand of the pottery maker to steak to the clay. In the historical period, using a transparent and colored glaze became widespread, but in the Islamic period the using of the glaze with various functions expanded. There are three main period in the evolution of the pottery in the Islamic era. 1. Early Islamic potteries 2. Middle Islamic potteies 3. Late Islamic potteries. During the rescue excavation in the Moravvej Historical House in Ardabil province in 2006, a vast number of pottery sherds mostly, belong to Seljuk to Safavid periods identified. This site located in the historical part of the city nearby the Sheikh Safi Al-Din Ardabili’s monument. Turquoise glazed potteries were the remarkable amount of the identified potteries in the above mentioned excavation. The questions of this article is on the subject of the turquoise glaze potteries; the amount and the type of the constructed elements ,and also study the similarities and differences between the glaze from different period. Five pieces (three sherds from 14-15 A.D and two sherds from 16-18 A.D) selected for the analytical studies with the aim of better understanding their constructed elements, technology and composition. In order to achieve to this aim, XRD and EDX analyses provided promising results about the technological aspects of the sherds, and also a comparative study not only was highly beneficial in clarifying the similarities along with differences of the composition of glazes, but also was helpful in better understanding of the turquoise glazes  in the larger region. Since there has not been applied any analytical study on the sherd identified from this site, this research would increase our knowledge about it. The pottery sherd divided into three categories, and then two samples from each category selected for the analytical studies. In the next step, technical characteristics of the sherds documented. After that, the pieces delivered to the laboratory for the analytical studies.  XRD analyses, was done in Razi Metallurgical Research Center using the Xpert Pro MPD system Panalytical model made in Poland. EDX analyses was done in Kansaran Binaloud Center using Micro Prob Horiba 7200 model made in Japan. Also, Peason Correlation Coefficient used for better understanding the correlation between different elements.

Discussion
Based on the XRD analyses, in the first sample dated back to the 14-15 AD, cristobalite, amorphous, quartz and silica were the main elements. Quartz, cristobalite and silica are the different phases of SiO2. Based on being buried,  the amount of silica decrease and the other elements increase which are shown as different picks. Quartz ingredients changed to the cristobalit as a result of increasing the temperature while baking. In the second sample dated back to the 14-15 A.D, calsite, quartz and silica phases reported. Quartz and silica represent SiO2, and calsite indicates the destruction process and release the alkaline ion from the glaze and formation on the surface of the glaze which regarding the date of the pottery and being buried, it seems reasonable. In the third sample from Safavid period , gypsum phase reported. The mentioned phase represent the destruction of the glaze as well as releasing the alkaline ion like calcium as a constructed element of the glaze. In the forth sample from Safavid period in addition to the silica and quartz, cesterite phase represnt SnO2 which functioned as a flatting element in the glaze. In the fifth sample dated back to the 14-15 A.D, in addition to silica and quartz phases, nepheline synenite was reported because of the slip. 
Based on the EDX analyses, copper functioned as the primary element for making the turquoise color. The amount of the copper in the samples is respectively 3/19%, 1/15%, 3/53%, 1/39% and 1/36%.  The glazes have an alkaline base since sodium, potassium, calsium, mangesium and stroncium was reported in EDX analyses; This means that the samples of this research have an alkaline base unless the sample four. The amount of lead in the samples respectively is 13%, 0/17%, 0/27% and 12/64%; this element was not reported in sample five. Comparing to the other samples, sample four shows a great amount of lead (12/64%), and also have 7/07% amount of tin. Calsium solfate was reported in the samples; the amount of this element is respectively 4/06%, 2/35%, 2/75%, 3/72% and 2/67% which mostly is as a result of the destruction during the decades. The first sample represents the most amount of the calsium solfate comparing  to the other samples. The aluminum is respectively 4/06%, 2/25%, 2/75%, 3/72% and 2/67% which indicates the destruction during time. The most amount of destruction belongs to sample one and then sample four and is almost equal in the other samples.
   
Conclusion
In Iran, the most ancient usage of glaze has been reported from the ancient site of Susa as well as Choghazanbil located in the southwestern part of country in Khuzestan province. In the Achaemenid period application of glaze on mud-brick of royal buildings was one the common architectural decoration methods. In Islamic period, decoration using the glaze was widespread since it can be seen in buildings namely masques, schools along with potteries. In general, the Islamic potteries can be divided into two distinct groups: glazed and unglazed potteries. In this article, five turquoise glazed pottery sherds have been studied in order to identify their elements, composition and technology. The mentioned sherds dated back to 14 - 18 A.D (late Ilkhanate, Timurid and Safavid periods), and identified from a historical house called Moravvej-e Ardabili House, in the historical part of Ardabil city. EDX analyses indicated that the copper is the main element which used for creating the turquoise color. It is respectively from sample one to five,  3/19%, 1/15%, 3/53%, 1/39% and 1/63% in the samples and shows that sample three have the most amount of the copper in the glaze. In addition to this, chromium has been used as a coloring oxide in this sample. chromium in the glazes is a key factor in order to making the different shades of green color and this is why the color of this sample is much more different than the other samples. Based on the analyses, glazes have an alkaline base as a result of  high amount of the alkaline elements such as potassium, sodium and calcium in all samples. The amount of lead compare to the alkaline elements is a negligible amount unless sample four which a considerable amount of lead (12/64%) was reported; The amount of lead is respectively from sample one to four, 13%, 0/17%, 0/27% and 12/64%;This element was not reported in sample five. Also, in sample five, nepheline syenite indicates using slip on the pottery. Regarding the statistical analyses, generally there is a signnificant correlation between the samples. The high amount of the correlation is in samples two and five dated back to 14-15 A.D as well as the less correlation is between sample four dated back to the Safavid period and sample five belongs to 14-15 A.D which is seems resonnable.
