Glass Pouring Chemistry of Materials, Fall 2017 Students work in the lab during Associate Professor Matthew Ray’s Chemistry of Materials class in Jarvis Hall Thursday, September 28, 2017. Pictured is the class comparing amorphous glass behavior with the crystalline solid behavior observed in the first part of the lab. They prepared batches of soda lime glass and varied the ingredients to change the melt viscosity and color. Glasses of various colors were prepared by adding small amounts of metal oxides to the glass mixture before firing to melt and react all of the ingredients together. The glass mixtures were placed into crucibles and heated overnight to 1150°C (2100°F), then poured onto an iron slab and allowed to cool. To observe fluorescence, the europium and terbium doped samples were illuminated with an ultraviolet lamp (365 nm light) which revealed the bright red and green fluorescence.
