Vitroglyph™ uses a 975lb propane fired, computer controlled daytank furnace, which maintains a minimum temperature of 2100 degrees Fahrenheit 24 hours a day, 7 days a week. 
     At the end of each workday, cullet (100 % industry recycled chunks of broken glass) is charged into the furnace and melted over night. After 10 to 15 hours at temperatures exceeding 2300 degrees Fahrenheit the glass is ready to be used again.



     Using heavy steel ladles, the team pulls the glass from the furnace. 

     At the casting temperature of well over 2200 degrees Fahrenheit glass has the consistency of warm honey.



     Excess glass is trimmed from the edge of the ladle to ensure a clean pour.
     Then the glass is carefully poured into the preheated cast iron mold. The thickness of the casting depends on the "eye" of the casting team.
