Just to clarify about a glass platen:
A "glass" platen for a grinder is pyroceramic glass. It can withstand around 1500°F without breaking. It is very hard (Rockwell 60) and strong when glued to a solid backing plate. It is designed for high heat situations like fireplace doors. The main reason for using it on a grinder is it is very flat, cheap, and readily available. I hear people say they wear it down fast. I have only ever replaced a pyroceramic platen when I broke it by setting the arm down on the floor too hard. I never saw any wear on the surface otherwise.

Tempered glass is designed for windows and entry doors to resist impact. When the impact is greater than its yield strength (about 3 times the IMPACT resistance over pyroceramic) it is designed to shatter into thousands of 1/4"/6mm pieces with no sharp points. It isn't harder, just tougher than pyroceramic glass.

Since a glass lined platen should not be receiving impact, that is a moot point. What a platen does receive is considerable heat. Tempered glass would be very inadequate for many of us who do hogging of blades.

Tempered glass is harder then ceramic glass . Tempered glass can withstand more temperature then you will ever create while you *hogging* steel .
Well , I make phone call today . Friend have glass factory so they will deliver it to me tomorrow. 26 x 5 x 0.8 centimeters so I can make some test and compare them

I'll just let it go .. but checked again with the manufacturers and the info I gave was from their site. I agree that tempered glass is harder, but it is not 4 times harder. The temperature tolerance is much greater for pyroceramic glass. I hope your experiment works well.

Have these eight on the bench post heat treat and temper - walking them through all the different grits today, 120, 240, 320, 400, and a 500 Rouge Impregnated Scotch-Brite and cutting some guards for them - Boat Load of Knives ~ Big Bertha looks sort a like a Sled ~ I like it ~ Stout Bowie and Cleaver in one ~

Got them all done on the different sanding belts and 500 rouge + scotch brite, think I'm going to get to the guards another day, possibly tomorrow ~

On impact . Come on Stacy , we don't use ceramic glass for quenching AEB-L so higher temperature tolerance is not important here . Why not to try when I can ? Thickness matter also , I can order inch thick tempered glass , that is not case with ceramic glass .
Well I ordered one but I get four :) That MF for sure would ask something from me ..............🤣 It seems to me that I will overpay for these glasses , it would be better if I paid right away . I'm kidding. What a fool I am !!! The measurements I took for the glasses for this plate are for grinder which still does not exist , it is not finished , so I can not test this glass right now !

Got home from work and a nice bar of S90V was waiting for me from NJ Steel Baron. Decided to work on a few more of these EDC designs. This one was profiled, drilled and the tang is tapered to .040 at the butt.

I have a question for everyone. When I grind a pattern for the first time (or even second) am I the only one that brings that blade/blank in and fiddle with it to get a feel and decide if certain aspects should be changed, like removing a fraction of an inch from the butt, or drop the point a tad.

Now mind you, I'm not talking about feeling the blade in my hand in the shop for a few minutes, I'm talking sitting on the couch, watching Archer or whatever for days.

Am I the only one?

All my blades have a "fiddle time". Sometimes the changes come to me in my sleep.
 
DangerZone!! Love Archer!

I tweak the design and play with almost all of my blades. I don't have any set patterns yet.

I got ceramic Norax and Trizacts in finer grits and they actually work on hardened S90v!!

The new ones for are get played with a bit trying to figure out the best handle shape or size and materials. Even the old patterns get some attention when trying different handle options.

The fondling time is my favorite time. Like figuring out the “buttons” on a new girlfriend.
 
I think anyone who looks for 'what's normal' in Bladeforums isn't going to find much
