Re: Question on speeding up cooling below 750°F

Reread the entire thread. All the guidelines you need are there.

Everyone's kiln and practice is different. You'll find out what your parameters are when your work starts cracking on cooldown.

Re: Question on speeding up cooling below 750°F

" Cracking the lid 1/2" just barely gives me a view beneath the lid."

There's nothing to see, move along now.
If you're in that much of a hurry (hurray?) then you need to buy another kiln.

Re: Too much chipping

Ice in the water! I'd like to hear the science behind that one. Maybe some vodka and a twist too? I have heard of surfactants being used in industrial applications. Seriously, if you're getting enough water at the right spots (I'm with Brad- warm water) it's the blade. Get the Result blade from HIS ...

Re: Vermiculite Board

I'd put the IFB on the inside. VB on the hotface will break down eventually and give you crumbles in your glass (although vacuuming before every firing will help with that). Actually, if you lay the brick on the flat (dry, no mortar) you get a 4" thick wall that won't need anything else, not fo...

Re: re-fusing a thermals shocked piece

Your thermal shock didn't happen at 102F (unless you threw cold water on it). What's your schedule?

Re: Kokomo for fusing?

Terry- That's a tall order. Does Kokomo date their batches and number their sheets? Do they do any testing? Are they interested in testing for compat.?
We'd be working in the dark unless they started formulating for fusing and keeping track of their stock.

Re: Help with crack

Your initial fuse of strips can be fast- 300dph- with a serious bubble squeeze around 1100. Subsequent firings of a piece like that shouldn't be any faster than 100dph (up to 1000F) because of the thickness and the black part. Every time I think I can get away with a faster firing I am reminded that...

Re: Help with crack

Well I understand the principle but can never get a clear answer on what is good. I can find all sorts of schedules for annealing but none for the turn up. Chris- My students want schedules- all I can give is guidelines; no one can give you the recipe for your work in your kiln (and what has "...

Re: Emissions and studio safety

But there's binders in the refractories that burn off, dusts from working with powders and from sandblasting, mists from coldworking. Common sense ventilation takes care of most, particle masks the rest.

Need more details- size and weight of drops? any loops on them or will you drill or cradle them? how visible can the cables be? how professional does this have to be? who's installing it? public or private space?
