The Bauhaus movement can be said to be the by-product of forming work pursued through the method of constituents even under endless discord between the so-called modern ages and anti-modern ages rather than to say that it was progressed consistently on the assumption of a design. Accordingly, all instruments of Bauhaus education which contributed to form the source of the modern ages realized educational value related to the actual problem at the point of time when the student evercomes all internal and production can be managed most effectively under one system was originated inevitably. The most exential point of the work of Bauhaus workshop is the fact that all products show homogeneity as time passes, which is appeared as the result of the spirit of consciously developed community based on cooperation between various characters and personalities. Also, the homogeneity does not exist in formative detailed aspect appeared externally but in the basis of effort having produced things simply and faithfully, and on the other hand, in accordance with essential rule. Therefore, the original form of Bauhaus products can be said not to be fashionable but the crystal of work process at the workshop through much thought and contemplation in view of endowed form following art, technology and economy.

The metallurgical investigation of four lumps of bronze from the third building site of the northern workshop site at the Neungsan-ri temple site in Buyeo was performed. The microstructures of a section of sample was observed by SEM and qualitative and quantitative analysis of the sample was performed by EDS. The results are as follows: Sample 1 of the lump of bronze from northern workshop site in the third building site at Neungsan-ri temple site and sample 2 are speculated to be low-quality bronze resulting from refinery of matte which formed on the process of bronze refinery. Sample 3 is speculated as a lump of bronze which is one of Cu-Sn system and the one made by alloy only with pure bronze and tin on the process of bronze refinery. Sample 4 is confirmed as a lump of bronze which is one of Cu-Sn-Pb system from alloy of tin and lead into pure bronze. It is believed that the third building site at Neungsan-ri temple site in Buyeo produced bronze matte by refinery of copper ore or produced low-quality bronze by melting matte imported from outside.

As the kettle excavated from a site in Hwangnam-dong, Gyeongju was presumed to have been used as a melting crucible in a glass production workplace, we decided to prove its usage by scientific analysis. First, we performed conservation treatment to find the original status of the kettle, and then SEM-EDS and XRD analysis of the five corrosions created on the surface of the kettle. The fragment of the spout, which played a crucial role for the kettle to be considered as a melting crucible, was discovered during the conservation treatment. So the mouth rim of the kettle was restored to perfection. When we observed the microstructure of the metal sample, it was proved to be cast iron gradually cooled without heat treatment. In the corrosion products, the main components were Fe and O and other components such as P, Si, Ca, and S were found. The main compounds were quartz, vivianite, goetheite, akaganite, lepidocrocite, hematite, etc. Although these components were used as raw materials for making glass, these were found not in the melting status but mere raw materials. This can be an evidence to show these site where the kettle was excavated had been a glass production workplace. However, it is not sure that the kettle was used as a melting crucible. Moreover, if we consider the organic mold and sand clay accumulated in the well site when the kettle was excavated at first, we can see this as a formative factor of the corrosions of the kettle. Therefore, we concluded that the kettle is a typical cast iron and was not used as a melting crucible of glass.

This study focused on the material characteristics and archaeometric relationship between the molten glass and bronze materials within the crucibles and gilt-bronze Bodhisattva statue excavated from the Ssangbukri site in Buyeo, Korea. Yellowish green to red brown vitreous material in the crucibles was identified as lead glass which contained scarce amount of BaO, and low $Al_2O_3$ and CaO. Metallic molten material was identified as bronze of copper-tin-lead alloy with low amount of impurities that indicated well-refined materials. Also, cassiterite was used for raw metal ore of tin. The Bodhisattva statue consisted of major copper with trace impurities in the core metal, and gold amalgam in the gilded layer. Though lead isotopic analysis showed contradictory results in each lead glass, bronze and Bodhisattva statue that required further examination, it could be stated that the statue was made in the Ssangbukri site based on the high-level technical skills of bronze production.
