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

Pottery is one of the most important man-made artifacts, and with time, its manufacturing and application technology has also changed. Therefore, in most archaeological excavations, pottery artifacts occupy a major part of the discoveries, and most of these artifacts have special damages. Some of these damages are common, such as fractures and cracks, and some are special due to the burial conditions and low quality in the construction technique; Such as body layering damage that requires special protection and restoration studies. In this study, a sample of terracotta cauldron hanging on the Segzabad hill of Qazvin Plain belonging to the Iron Age period was studied. This study aimed to understand the construction technique, investigate the damages on the pottery body and the cause of these damages. To answer these questions, instrumental tests, such as XRF, and comparative historical studies have been used. All these studies will ultimately help in the way of conservation and restoration that should be done. After all the protective steps to prevent secondary damage that may occur after its restoration, a box is designed to store the pottery and, in some cases, even display it. The result obtained from all the steps was the recognition of the construction technique and the documentation of the damage in the body, which ultimately led to the protection and restoration of this historical and cultural work.
