Slumping a cone
A broad cone shape (the shape of a martini glass) is one of the most difficult shapes to make using a torch. Has anyone had experience with making this shape by slumping the glass into a mold?

Hi Mike,
I don't have pictures of the cone shaped light fixtures I made years ago but the way I was able to get it shaped was a custom spun SS molds. These were fairly large fixtures and deep. I did slump the pieces into a larger mold first just to get the glass to start forming into a bowl type shape, I didn't want the glass to ruffle or wrinkle. How big is this going to be? You can get a circle cut from SS to put into the bottom of the cone shaped mold too where you want the base to be. Another way would be to do a drop mold and have the cone shape for the piece to slump into.
Good luck.

As I understand it, a lot of Schlanser's work is dropouts with the rims removed.

These are going to be fairly small, about four inches in diameter. I figure to roll the stainless into a cone, weld the joint and grind it smooth. Then I'll tack a small circle of stainless on for the bottom. I want an angle of around 45 degrees for the finished piece, so I'm hoping two molds (30 and 45 degrees) will do the job.
