"Watching Marlene Rose at work in her studio is a glimpse into some heavenly inferno. Once Marlene scoops up a heavy ladle of glowing, liquid molten glass from the furnace, she carries it to the sand molds she has carefully prepared. Attended by her crew, she carefully pours the glass into the molds. Like bright, white treacle it eases into the sand molds and begins to cool. Her crew immediately blasts the glass in the mold with fiercely roaring portable burners. to slow the cooling process down, and make sure there are no hot spots that might later crack off. In the mold the liquid glass changes color almost imperceptibly as it hardens, from bright yellow to orange to pale red and then to crystal clear. When it is at about 1000 degrees F it is carefully picked up (the crew wear thick, heat-proof gloves) and carried into a separate oven where it is slowly brought down to room temperature. This slow cooling process prevents the glass from cracking, and can take from 5 days to two weeks.
