Help Inducing Devit on Float(tempered) Fusing temperature

Can anyone help me on finding the rite temperature to induce devit when
fusing tempered (float) chunks together for a 16 inch square blank. I really like the devit especially when using for a wall sconce !

thanks Ive already tried

My ramps have been
350-1000-10
700-(fuse)-(hold)
Full-980-2.20

My hold Times are

1520 - 30 mins (just fired clear)
1500- 15 mins (barely even fused) But very kool

Try 1 1/2 hours at around 1760F. (Exact temperature varies depending on your kiln.) Don't clean the glass before firing, and don't be afraid to pray to the devit gods. Good devit is definitely an art form.

Also, go to the Old Archive (button at top right of page) and search for anything on devitrification by Brian Blanthorn. Lots there, though it may take you a few readings to follow it all; Brian has a somewhat unorthodox writing style. (But he is generally acknowledged as the Founder of the Society for the Preservation of Devitrification and is probably the world's most knowledgeable person when it comes to devitrification.)

Depends on what kinda devit U want

The glass devitrifies fury or kinda spikey

U can control where u dont want it with anty devit stuff

Glass devits best arround the time it moves so allow it 2 move a little then soak

Watch out if it gets thick it will probably crack as usually incompatabble

Fine sandblasting is pos easiest way 2 get it 2 start

Dont clean it 2 well

U could also paint it with very very fine layer of china clay ( kaolin )

Ur link not work

Thanks soo much sorry about that link, i think I linked it to my Webshots soo its only good from my CPU. Really sandblasing will do the trick, cool.
Havent been able to afford one yet but, soon hopefully. Wow ! I've been reading up in the Old archives, Brad this site is somethin else. I could be there for weeks reading. Good thing I like reading only interesting stuff, withh my ADD and all. Thanks for thet tipps everyone. I'll try and figure out the picture thing, sorry bout that it's pain.

Probably SLS is the best glass 2 devit

BE etc is made 2 not devit

As it pools out the devit will rip

By riping n anti devit stuff u can reduce the neucleation points n get nice big cristals

The bace colour of the glass affects the devit

Posted a snow link on devit recently

Brian is the aknowleged master of devit.

You can imitate devit with any of various cream etch or dip etch products. The one I would be looking at is for sale by HIS glassworks.

This may seem kind of off track, or not. I'm not sure what I have here. I put some small pot melts in a bowl of Lime-Away to get some persistant kiln wash off the backs. The tops were nice and smooth. I forgot about them for 3 days, and they sat in the Lime-Away all that time. When I pulled them out tonight, and washed them, they not only dried with what looked like devit crystals, but the formerly smooth tops were eaten into. Every little wave of the potmelt is not only visible, but is actually textured now. And the crystals persist even after washing and scrubbing.

Not what I was going for at all, but did I grow my own devit by allowing the Lime-Away to attack the lime in the glass itself? If someone was looking to induce devit, could they let this stuff do some of the work for them?

At room temp glass is 2 stiff 2 devit

U either got cristals there from B4

Or the lime away has cristalised on2 the glass or somethig weird is going on

Like it is desolving the glass which is then cristalising

Some colours will B more suseptabble than others

Thanks Brian

My vote is for dissolving, crystalizing and weird.

They have been dumped in a tumble-vibe to try and unweirdify them. :)

I am no expert in this field

But I do belive some class is made with a cristaline structure like opals n shuch

Glass is actualy a very complex subject once u get a way from the clear stuff

When ever I meet a expert or hear about one on TV

I think I wonder if they know as little about there subject a I do



While we on weirdness there is a branch of glass called glass ceramic

U make it like glass then devitryfy it n turn it into a ceramic like material
