Sticking temperature of stainless steel
Does anybody know at what temp glass starts to stick to stainless steel ??
I have a project where I will not be able to use paper or kiln wash on, and I need to fire to about 1200 degrees.
So, does stainless stick to glass if it is 1200 ??

What about irid? will that act as a seperator against SS?

Re: Sticking temperature of stainless steel
I can't say as I know just what temp sticking starts, but I agree with Brock. Why no kiln wash? You can use sifted powder maybe. Talc or whiting or alumina or kiln wash or Boron Nitride that is rated for 1200.BillBrach wrote:Does anybody know at what temp glass starts to stick to stainless steel ??

I would think irid would act as a separator and you should be able to drape over an uncoated stainless. I have bent over stainless with only a dusting of 'Free' by Satelite Products. I think that 'Free' is simply talc.Stuart Clayman wrote:What about irid? will that act as a seperator against SS?
I'm with the rest though, why no separator?
Sorry I didn't give enough information in my original post.
What I'm trying to do is coat kiln made beads on ALL surfaces with anti-devit spray, and then run them through the kiln. I have to grind extensively on these beads to shape them, then obviously they need to be "shined" back up.
I don't want to have to run them twice thru the kiln to shine all the surfaces. I'd planned to slide them on an UNCOATED ss mandrel and fire at 1200, using "Back Magic" as devit.

So far my understanding is that Back Magic has some type of magic power to get people like me to buy a product that does not work. Have you found a use for it? It does not work as they say it does to shine up the back of a product.

I don't get why you wouldn't coat a ss wire, string the beads and either torch them or kiln fire polish, then remove the beads...BillBrach wrote:Sorry I didn't give enough information in my original post.

I'm with Stuart here. Back Magic doesn't behave as advertised, although you can probably fire polish beads at some temp or another, just not 900. It has a high lead content so don't eat your beads. I bet 1200 works though.

I have tried what you are attempting and the only method I was successful with was using a tungsten or graphite mandrel. I used a small kiln to get the bead up to 950°F and fire polished the bead in a torch. I think that going all the way up to 1200°F you will risk having the bead too soften much in a kiln.
