Apparently I can blow glass too....

As part of my current project at Uni, I have been experimenting with applying the same surface treatment to ceramics as to glass.

I have been casting and carving in to plaster, then I have been press moulding or slip casting with white earthenware into that, and then doing bas relief "kiln carving" with float glass.

This plaster tile was a simple design of a trace of dots, which I thought would work quite well as t texture.

I really didn't expect this reaction though!

I don't know if there was something in the plaster, or something on the surface of the glass that as it burnt off created gasses that couldn't escape - but something created this wonderful bubble!

The glass is about 10 cm square, and the bubble stands about 8 cm high, and at the very top, it was so thin it was flexible (so much so that it didn't take much of a poke to put a hole in it!)

I don't know what to do with it, and I doubt I could do it again - I wish I could. But I certainly didn't know that I could blow glass in my electric fusing kiln!
