The higher-ups at my highschool art club have a question.
We have this festival thing coming up and one of their ideaas was to melt wine bottles flat for trays etc. The problem is them mold they tried blew up fantastically in the kiln, and they read somewhere that they needed silica (?) in the mold mixture but they don't know how much.
Anyone with more expertise?

I have a friend that does this with wine bottles. Just lay the bottle on it's side in the kiln on a kiln shelf heat slow, fast heat with explode. Take the kiln up to 1500 degrees very slow and vent the kiln too. I will ask my friend how she does it in the mean time find out what kind of kiln they are using.

That technique is called "slumping" or "warm glass". You can make all sorts of neat items, but it does not have the range of fusing.

This is a good resource for melting glass:

i think you can use sand. i have not yet melted or fused glass *im just a humble glass blower* but im pretty sure they use sand to for fusing and melting at my college. so you could give that a try. the idea of just melting it on the kiln shelf might ruin it, the glass will melt to the shelf and you might not be able to remove it. but im not tottaly sure so research that idea a bit more.
Best of luck
