Naderi Tepe is located in the southeast of Mashhad and is located next to a communication route. According to the typology, the wares of this site include the variety of species and the quantity of pottery pieces from the Chalcolithic to the historical period. During the study of this site, based on the obtained wares, 10 pieces of the sherds and two pieces of stone quern were analyzed by petrography and their thin sections were examined in order to find the minerals in them. The purpose of this experiment was to identify the components of each sherd, the difference in composition and materials between samples, determine the percentage of each composition, determine the temperature of pottery firing according to the available minerals, and investigate the origin of the raw materials that make up wares. In the laboratory, a thin section was prepared from the pottery and then studied with an optical microscope. The results of the studies show that the mineralogy of the sherds from the site shows the better quality and purer paste of the sherds produced from the middle Bronze Age to the end of this period, which shows the high skill of the potter in making and knowing the raw materials in the production of pottery. The results of this research can be the basis for the comparison of ware types in terms of construction techniques and compounds used in them in the surrounding areas, especially in the Mashhad Plain.

In the second half of the fourth millennium BC. Southwest Asia underwent social changes, the result of which was the emergence of writing. In these developments, the cuneiform script in the south of the Mesopotamia and the Proto Elamite in the Iranian plateau progressed rapidly to such an extent that at the beginning of Elamite was scattered throughout the Iranian plateau. These writing systems were used for administrative and accounting purposes, and despite the fact that most of their signs are different from each other; there are important similarities between the two. Chalcolithic era, the best period in which you can see the idea of trading's and keeping of account; for the first time in this course, tools are seen which called them Token; it seems that the tokens in a variety of forms and counting symbols refer to a specific concept. The end of this period coincides with the Proto Elamites era in the south and southwest of Iran. Domestic production in the Neolithic period gave his place to the production of a workshop in the Chalcolithic era, which causes a lot of production. In the present study, firstly, will be investigated, small clay counters and then the Proto Elamite texts.

In the east of Pahanvar Ray plain, we come to a fertile area (Pishwa/Varamin plain) which has provided suitable conditions for human habitation since the formation of human settlements until today. Due to the location of this plain in the north of the central desert and the border between the two cultural domains of the northeast and the center, the environmental condition and suitable altitude, which are the main factors for the formation of permanent settlements, and the possible existence of extra-regional connections of this area with the neighboring areas, a wide survey was conducted in this area of ​​the plain. It was concluded that during this archaeological investigation, 61 ancient sites from the Sassanid era were found in the east of Varamin and south of Peshwa. It is most likely that Varamin is considered a part of Ray State and based on the available evidence, it is possible that it is the main center of Ray State as well. According to historical texts and archeological data, the state of Ray was one of the important areas of human settlement during the Sassanid period in Iran. Historical texts mention Ray in the Sassanid period, and the number of sites attributed to the Sassanid period in the geographical area of ​​Varamin has not been found until today. Despite this, based on the prominent geographical location of the Varamin region and the references of the historical texts to the Ray state, this region was probably one of the important regions of the historical period in Iran. In the present article, an attempt has been made to describe the historical geography of Ray State in the Sassanid period, while using the archaeological data of the Sassanid period of Varamin, to draw a part of the archeology and historical geography of Varamin in the Sassanid period.
