| Abstract Scope |
Between 2001 and 2005 archaeological investigations were conducted near the German town of Glashütten. The site revealed a fifteenth century CE glassworks, known as Unterhalb Dornsweg. Findings at this site included many vessel fragments and additional shards of an opaque red soda lime silicate glass. A previous study concluded that the opacity of the red glass is likely caused by microcrystalline cuprite and the red color specifically is due to 60-80 nm diameter metallic nanoparticles. Initial experimentation demonstrated that upon remelting in an electric furnace the glass became transparent, green in color, and sputtered significantly. This presentation will discuss the history of Unterhalb Dornsweg, both the site itself and of the archaeological investigations, highlighting the efforts of the residents of Glashütten. Additionally, preliminary results relating to the composition and behavior of the red copper glass are presented and future work is outlined. |
