Abstract

The pathology of pottery works is considered one of the most fundamental pillars of conservation and restoration, as understanding the damage will pave the way for its preservation and restoration. Pottery works are generally more stable than many other materials found in archaeological excavations. However, when these works are buried in inappropriate conditions and unfavorable factors, they can suffer from significant damage. Without proper care in their protection, the result may be complete deterioration of the pottery. Damage to ceramic bodies occurs in two forms: Physical and chemical, along with mechanical factors, can accelerate these processes. In the pathology of clay bodies, it is essential to identify the origins and causes of these damages to implement the effective treatments aimed to enhance the longevity of the ceramics., In the pathology of clay bodies, we can refer to cracks, fractures, crystallization of various salts, damages from firing processes, biological damages, stains, delamination, and more. This research, will provide an overview of the most prevalent damages of clay bodies and the factors that cause them, and the relationship between the formation of one type of damage and its influence on the emergence of other damages. Recognizing these connections can inform more effective methods for the protection and restoration of pottery artifacts.

Abstract

Ceramics and the ceramics industry have undergone numerous changes since the emergence of tool-making humans on Earth. These changes have led to the development of various types of ceramics, differing in shape, design, nomenclature, size, preparation and Making methods. These are primarily found in archaeological excavations, and their conservation and restoration can be more accurately performed by understanding and identifying their types and varieties. Ceramics are classified into different types based on their manufacturing technique, firing temperature, the clay used, and the additives used in the clay body. These classifications can sometimes be quite scattered. For instance, based on firing temperature, they can be divided into four categories: stoneware, earthenware, bone China, and porcelain. Based on manufacturing methods, they can be classified into hand-built, slab-built, wheel-thrown, molded, and pressed. The aim of this research is to introduce the most important types of ceramics and their characteristics, including firing temperature, manufacturing technique, and other structural properties and materials used in the body. To achieve this goal, this study will explain some of the terminology used in ceramics and classify ceramics based on firing temperature, manufacturing method, and the type of clay that constitutes their clay body.

Abstract

A large group of Islamic-era ceramics consists of splashed ware and sgraffito pottery, which are of significant historical and technical importance. This study aims to reconstruct the production technology of splashed ware during the Islamic period in Iran by examining its formation process and technical fabrication stages. This research seeks to answer the following questions: What was the process of splashed glaze formation in Iran? How can the technical stages of splashed glaze reconstruction be achieved based on the study of samples? To this end, 100 studied samples were examined, and 10 specimens were purposefully selected for experimental reconstruction of splashed ware. The research methodology is applied, utilizing historical analysis and experimental testing to produce samples of splashed ware ceramics. The study samples were carefully analyzed to understand the materials and manufacturing processes involved in splashed ware technology.
