OK, i feel obligated to get an entry in this month. I'm not confident in this one as a decent contest entry, but it goes with the Halloween theme. It is snowflake obsidian that I collected in Utah. I call it "The Witches Heart".
I have a love/hate relationship with obsidian. It is so beautiful when it comes out well, but it is completely unforgiving. I had to drop back a wheel multiple times while working on this one, even after drying and carefully inspecting between stages. And still there are imperfections that bug me now. But it is fun to cut and I have gobs of it to play with. And it demands a lot of me so my skill will only grow as I work with it.
The slab is here amongst many that I have cut recently.
Preformed, ready to hit the wheels. This ended up being the back side.
Finished cab. Another reason I struggle with obsidian...photographing it is nearly impossible!! Every tiny imperfection or speck of dust shows up.
