Using Kiln Wash As A MOLD

Tyler Frisby · Post by **Tyler Frisby** » Sun Dec 07, 2003 11:33 am

Im in the Experimenting stager ight now but has Anyonw tried using Kiln Wash as a mold Before ?

IM talking about using 2 inch kiln washed post and fillling the midle with kiln wash then evening it out to be flat with the 2 inch posts.

Then you have a square "2 inch High Of kiln wash, Use a piece of glass to smooth it out , then Try depressing your palm print into it. Lay the 1/4 (2) inch glass (FLOAT) on top and Slump , But whatch for bubbles though, make sure to leave no room betwwen kiln wash and the Float glass, I've already ruined one Firing.

Just trying this out , if anyone hasnt tried it, Check it
If soo have I been trying it right.

Thanks Tyler

Yes, we have used kiln wash as a mold for many things... it works fine. The downside is that you can really only use the mold once without it being damaged and then you have to replace it with new whiting. Repeating the procedure can be tiresome if you're using the technique a lot, not to mention a mess.

I have posted a lot about casting with variuos refractory powders. I have used a mixture of Alumina Hydrate, diatomecous earth and plaster with pretty good results. My latest mold bed is olivine sand 80% and plaster of paris 20% with a dusting of plaster after the mold is formed.

Tinted tempered glass can be fired as long as you can heat the whole piece at once. After you have reached 1100ÂºF it is no longer tempered and will behave just like any annealed glass.

Q = So you mean for tinted temperd I dont have to break it first ?

I thought that the temperd would explode in the kiln If I didnt snap an edge first.

Interesting, that would be kool. Im playin with Devit rite now and am Likeing that effects it has on temperd, particualarily Clear Temperd.

Q = Any thoughts on the best way to to Induce Devit ?

if you cut the edge, you'll be left with a shop full of glass fragments that you'll be finding for years.

I ask does that mean I dont have to break it first if i fire it to 1100

no you do not have to break it first. i was cutting some 1/4" scavenged glass for a friend. it was a big piece so i was working on the floor of her shop. scored it ok. flipped it over and tapped it with my trusty 'bert-o-tapper' kit. nothing. tapped harder. nothing. WHACK. the piece exploded in all directions. it was tempered. it was such a cool looking event and the mess was already made so i got another piece and whacked it just to watch it break. ms destructo

not only do you not have to, you should not. once you heat it to 1100 it is no longer tempered, so you can then cut it safely after that.

One of the traits of tempered glass is that it is more resistant to heat shock so it can be heated faster and more unevenly than annealed glass, without breaking. Once it has passed the strain point, it is not tempered any more.

Tempering has nothing to do with color. Tinted float glass comes in a very limited array of colors, gray, bronze, light blue, light green and a few others made in Europe.
