Glass or ceramic , what do you guys suggest ? I have both .On first grinder I have HSS, so I have no experience with glass and ceramic ?

If glass is not tempered(refractory glass)....option is ceramic

You want pyroceramic glass. Same glass they use for fireplaces.

Like so

Hey , I m good student here , I learn what glass is good for this taskYes , it is borosilicate glass . But I don t found any comparasion that s way I ask .Pyrex or ceramic tile ? Which one is more durable and more safe for use ?

Well , obviously I will need to find answer by my self I cut ceramic tile in 50 x 180mm pieces and I buy 4mm x 50 x 180mm . Pyrex glass for 3$. Rubbing between finger piece of belt/back side of course/ on glass and ceramic and on HSS plate I have ........The feeling is that Ceramic tile surface have at least four time more friction then glass ? HSS also create much more friction then glass .So they will create much more heat ? But ceramic tile a deliberately designed not to slip ??? I wonder if it will improve over time ? I decide to make another plate for Pyrex and compare both at once ..........

I use High temp silicon to glue .Have notch on bottom side to hold ceramic tile .

If I have time today I will finish this plate for pyrex glass .And make comparasion .

Now I have question ...is this pyrex glass ? This is old glass from my kitchen cooker ? My son is living proof that foolproof material not exist I can cut many piece if it is pyrex glass ? Never mind , I just found answer ....google say it is ceramic glass
