This study focused on iron making related information through analyzing slags and furnace wall collected from iron production site of Suryong-ri Wonmorongi, Chungju. Total Fe content of slags were from 36.98% to 44.47% and this range was general recovery rate of iron in ancient. Compounds of calcium included slags was supposed to add intentionally during smelting process as deoxidation agent in order that these helped to separate iron from impurities. Furnace wall didn't make of high alumina clay because of low $Al_2O_3$. Microstructure and main components of slags show that No. 1 to 3 slags with fayalite and wustite were products of iron ore smelting. However, No.4 slag is more likely to smelt by iron sand because of ulvospinel with $TiO_2$ in No. 4 slag. Therefore, iron ore were not only used but iron sand in smelting and furnace wall made of general clay with low $Al_2O_3$ content in this area.

After excavation work of relics, historical site which has historically meaningful, are preserved using the various methods. There are three method in the relocation methods that are original relocation method, the remaining structure-peel method, and soil peel method. The original relocation method is restored after relocating in historical site such as residential site, iron foundry site, kiln site, old mound. The remaining structure-peel method are restored only the feature of exposed remaining structure using polymeric resin, when it is difficult to relocate the entire remaining structure. And soil-peel method is exhibited after peeling in case when soil layers such as grave of old mound, foundation of building site, sedimentary deposit layer, shell heap, and etc. Soil-peel method becomes important historical data of changes according to environment at that time, that is, flooding by storm, traces of fire and living features of that time such as heaps of shells discarded after eating shellfish and living wastes. In particular, in case of soil layer for preparing foundation sites of building by compacting in turn soils with different components such as clay soil, rough sand soil and etc, it becomes important data which can judge foundation technology of that time. It can be said to be an important data preservation method for utilizing these historical data as historical data as well as for the purpose of education, exhibitions and public relations which can be shared not only by experts but also by general public. In this paper, we present the reliable definition of soil-peel method in various preservation methods and explain the using polymer in this method. So, we will come up with the accurate index about this method that is used the eminent analysis method for soil layer.

To figure out the material characteristics about slag and raw materials which are founded in iron product sites in Seosan area, we used XRF, EDS to analysis chemical compositions. Also we observe the microstructure by microscope and SEM. To identify the mineral component, XRD analysis was used and to assume the provenance of the raw material, lead isotope ratio analysis was used. From the results, we figure out that slags are non-ferrous created when metal was refined. Also, main tissue of slags were Fayalite, Galena, Magnetite, and raw materials were identified as mineral of Galena, Anglesite, Pyrite etc. From the result about lead isotope ratio analysis, we found out most samples are classified as the Western Gyeonggi massif in South Korea. Especially three of raw materials and slag samples which collected in the Seosan Doseongri was presumed to be the provenance. We figure out that slags we analyzed were made in non-ferrous metal smelting process and especially that were more likely to smelt from Seosan Doseongri. If various slags in this area are analysed by someone, It will contribute understanding non-ferrous metal refining process as well as metal refining which are composed.
