For those that wanna get some more knowledge on the subject
The growth of ice is very similar in many respects
In the article note
No neucleation points = no ice
This is also true of other materials which can exist in a cristaline / liquid form
In glass when using anti devit stuff the newcleation points R disolved and or the surrounding glass is 2 liquid 2 grow cristals
I n my buddies have a lot of stuff in the archives on devit
Thanks Ron 4 the original link

Thanks Brian and Ron. Interesting article. I always am wondering what physical-chemical reactions produces anti-devit stuff. I think anti-devit can't drop liquidus temperature enough to prevent crystallization from occur. I might vote for a nucleus dissolution mechanism, however I would like to know for sure.

Hi Hugo
If the glass is 2 liquid the devit cant grow
Normal glass with devit in it heated so realy runney, then devit will disolve
The anti devit stuff does this but at a lower temp

borax on enamels
So I have new work that uses enamels (Thompson) on float. I've got very light devit in the non-enamel spots.
If I spray some borax will it have any negative effects on the enamel?
Thanks,
Paul

There was some chat about borax being water soluabble over time
If the enamel has 'devit' on it n the enamel is liquid / shiny
My guess is its not devit
A molten enamel should not B able 2 devit as it is 2 liquid
MayB fire higher ??
