Hello everybody,
I need some help about mold making/firing schedule for slumping thin (1mm)glass. I must warp a little a 8x8" piece of clear float glass (I must take the shape from another -original- glass)
Thanks

You have 2 challenges. Thin glass weighs less so there is less force pushing down on it. 8" x 8" is a small span, so there is not a lot of weight pushing down as well. It is not that difficult to get the glass to slump, if you don't care about adding some texture. If you want it unmarked, it is difficult. Fire to 1140ºF and wait until it attains the shape you want. The tin side will fog up in places where it is compressed.

Thanks for help. I need this glass for plating- so adding texture it's a problem...any advise about the mold?

What kind of shape are you trying to achieve? Is it a gentle bend, or more strong curve? Is it for a furniture setting?
You can take a mould from the original shape in various materials and then make a refactory mould from that.

It's a gentle bend. I'm plating an old painted piece of glass with multiple (bonded) cracks. It's some kind of reinforcement of the back. The original it's bended to ( helical twist)
