Pyroceramic glass liner for flat platten

No, that is tempered glass, not pyroceramic. Darren Ellis sells it in any size you want.

I got good results with pyroceram on my platen, but got the ever lovin' hell shocked out of me every time I used it. Eventually I just took it off because I couldn't take the pops every time.
 
Tempered or plate glass will work just as well as expensive pyroceram. i just buy 1/4" plate glass and it works fine.
 
You may want to invest in a can of Static Guard and spray it on the back side of your belts to help keep the static shock down.

It is not dangerous to use tempered fireplace screen glass for grinding, you say. Safety is all I want. I didn'n know, that there is so much variety in the world of glass liners.
I have a milimeter of a tooth in the down side of my platten to hold the liner. I have hardened steel up to 58 RC, but it is wavy allready after 10 knives.
 
I spoke at length to a local glass shop. looking for pyroceram, initially. i told the woman what i use it for and asked for her input on it. pyroceram and tempered glass can withstand alot of heat, but the heat barrier is only a baked on coating which our belts quickly wear off. she suggested i try cheap 1/4" plate glass. thats what i've been using ever since.

i hav'nt noticed any difference between the plate or pyroceram..,other then price!
 
Has anyone noticed if either alum or steel JB weld helps to bleed off some or all of the charge build up on glass/ceramic platens? I have never tested it's conductivity when dry.

I only use a HT'd O1 plate but I am still curious about pyroceram. Even a small amount of conductivity should bleed off most of the charge build up.

Has anyone tried connecting a ground strap from the glass plate to the grinder frame? That should not allow the glass to become a capacitor.
 
B Finnigan, capacitor is two eletrodes with insulation between. Knife, belt/liner,platen base.
Cannot beat the static. I have never tryed a glass platen, but with that static problem it is kind of nasty. I am thinking of 01 - brine quench, without draw....... And heavy ground wire.
 
Get a can of anti static clothes spray and give the belt a two second spray on the inside as it's moving. Frank
 
I use a pyroceram and i've never had a problem with static discharge. What I have noticed, however, is after awhile the ceramic tends to hollow out a bit in the middle. I guess they aren't good forever, even if they appear fine.

This is my experience as well. Never gotten shocked. I use epoxy to attach it to my platen. And, yes, they seem to dish out fairly fast...
 
pyroceram, pyraceram and pyrex are all trademark names for low thermal expansion "glass" made from borosilicate vs. typical silicate glass. Fireplace glass is also normally a lower thermal expansion glass and could be any of the above in private label version or a generic ceramic (borosilicate or some variation of it) glass. It absolutely will wear down but at a much slower rate than a steel platen. I have purchased and sold all 4 versions of the above. I have also used safety glass.
Safety glass is 'normal' glass with a layer of plastic in between two sheets of glass and will crack from heat much faster than a ceramic fireplace glass.

I keep a can of laundry spray static guard and use that on the inside of a belt if the shocks get too bad.

If you can find fireplace glass locally for a good price, that is probably the way to go. They will normally make a cut or two free of charge but you will have to buy at least a square foot of it and that is where it gets more expensive than just buying a piece online.
 
I went to my local stove/fireplace guy, who happens to do blacksmithing on the side, and he cut me a piece from a scrap and gave it to me for nothing. It has worked like a charm for quite a while now.

what a deal , my glass company here wants $65.00 a sq ft. before cutting to my size needed .
