Here's some pictures of my first two attempts at doing sculpture work with borosilicate glass (think Pyrex). This type of glass is Very different to work with than the soft/Bullseye glass I use to make little fusing bits. It's very slow to move and heat up, which can be both a blessing & a curse. Plus there's the fact that it doesn't want to shock as it cools down much (or at least not as much of a tendency to do so than soft glass does - found that out yesterday, yikes!)
To give some perspective, this vase-thing on a stand is 7.75" tall. The flower hits 4.5" tall.
Now, these two items I can't sell at all - they both developed some hairline cracks in their assembly/final cooling so their structural intregredity isn't the best. However, they're quite pretty to look at, and are a fun preview for the types of things that could be done with this material. :)
Oh, did I mention the colors?? Boro has such a larger range of colors and color effects that you can get with it than soft glass, it's just amazing and fun to play with. Take a look at the root-like base of this flower - that's all one color of glass, and it just happened to hit all those various colors.
