Topic: Fusing carnival glass?

[Max]

Does anyone know if you can slump carnival glass?  Does the irridescence make it unsuitable?   

[Anne]

Or would you need to slump it and then Carnival-ise it, I wonder?  Interesting question that, Max. Perhaps Glen will know. 

[Connie]

Glen will know.

But I think that the carnival treatment will burn if it is reheated.  I have owned some pieces which appeared to have been too hot when they were sprayed and there were burn marks or bubbles in the carnival finish.

[Max]

Hmm...burn?    That's a worrying thought Connie. 

Anne, I was going to slump existing carnival glass, bits of broken plates etc...I can do that at Uni - as long as they let me put that type of glass in the kiln!   

Edit!   Realised I'd made a mistake, my apologies for confusion!  It's really FUSING the glass, not slumping it - sorry!   

[Glen]

It depends how hot it got, but I think you could lose the iridescence. Certainly it is likely to crizzle and crack a lot (open up, a little like stretch iridescence).

Awww Max, I was thinking in terms of Carnivalised Fiestaware!    I'd love to try fusing glass.

Slumping glass should require no more than 700 deg to allow the glass to go malleable - not sure how that fits in with the carnival finish. Not sure the temperature for fusing, but probably about the same.

Coo, there's a thought!  <recoils slightly> 

Crizzling and stretch would be welcomed  sparks flying from the irridescence burning off wouldn't! 

Thanks for the tip David.

Sometimes Chance went as low as 620 deg. and I think it depending on the transfer or enamel used and the type of item being slumped. Simple slumps could probably operate at much lower temperatures.
