Silica is silicon dioxide, SiO2 ..... Available in 20 kg bags. It is used as the refractory ingredient to prevent the gypsum from breaking down in the kiln environment. No more than 50% mix with the gypsum otherwise the plaster becomes too weak to hold when red hot. Top heat 950c maximum for no more than 5 hours before mold will start to deteriorate. Recommended is 850c up to 12 hours..... this time is relevant to size of object..... general rule is half an hour per 1/4 inch, more is recommended. So a piece an inch thick is fired at top temp. for a minimum of 2 hours..... 3 would be better. Silica Flour. Silica is silicon dioxide, SiO2 ….. Available in 20 kg bags.

Thank you for this page! It's fantastic! I would like to try to make glass cube. But i don't understand exactly... "The elementary mold mix is one kg of gypsum, one kg of silicon flour to one liter of water." What is "silicon flour"? Silicon, like an inplant? Or silicium (SI)? Or what? Please, give me some information as soon as possible! Tnx: Dewill Hi! Thank you for this page!

And yes! Raw material does play a large role in the quality of a cast. From experience Gaffer Glass is the undoubted choice. This is a 40% lead crystal specifically developed for casting.

I have a studio with two large electric Skutt kilns. I have had some success but many failures using the lost wax method. I had been using Bullseye Glass but was recently told Gaffer Glass is the best. If you would be interested in sharing your knowledge, I would LOVE to learn all I can about this medium. I will leave my e-mail address and web-site. Thank you for your time. e-mail: sculpture@margaretwarren.com Website: www.margaretwarren.com Hi, I’m an artist just getting into glass casting.
