Gillinder coaster mold being created

Gillinder uses proprietary formulas and modern mixing equipment to create each batch of glass. Our furnaces are computer controlled and monitored to maintain precise temperatures and ensure repeat-ability. After forming, each piece of glass is placed in a 10' wide computer controlled annealing lehr.
