I was in my local craft shop with a friend who was in need of some picture frame inserts and I came across this...

Picture frame glass may not be as tough but it will do in a stop gap situation.

When I used to work, we built 'government' computers, scanners, printers, etc. The glass in the large HP scanners had to be replaced with a copper embedded glass to stop emissions. We threw it away. I cut a couple of pieces of the scanner glass with a new glass cutter and have been using the same 2 pieces for just about 5 years. I don't use Kapton tape as it is an insulator. I use IV tubing clamps to hold the glass to the bed as I remove each print as soon as it is completed, I refuse to waste the time to let it cool to ambient temp and take 30 min to reheat to operating temp. I use hairspray and have to pry the print from the glass. It works fine.

Keep it simple....

Looks great! I'm going to try some mirror tile, looks so cool. My current setup I can see the double sided tape through the glass, which is not the best looking for sure. Mirror will definitely improve the view.

until my tempered glass gets here I am using Mirror tile and hairspray.
working great so far and at $10.00 for 6 sheets it will probably
be a while before i install the tempered glass.

Thanks

Borosicicate glass cuts just the same as regular glass however the score line need to be firly hard and the break has to be completed along the cut line and evenly or you end up with broken glass.

If you go on Youtube, you will find plenty of tutorials on how to cut tempered glass, it DRILLING it that you can't do, if you couldn't cut tempered glass to size then there would be a prblem as all items needing it would need to have speciallt made sizes, that just doesn't happen.

If you watch how its made on youtube or TV catchup, watch the one about Pilkington Glass, they make tempered glass that is meters wide and as long as a lorry and the glass comes off in a constant process, when cooled, the machine cuts and breaks glass and it does not shatter.

Well theres old and there's old...

Older scanners are often junk these days BUT are better built, more accurate and higher resolution.

My scanner I have at the moment can scan at twice the DPI than one you buy today. Main reason is counterfeiting had taken advantage or ultra high resolutions you got on old scanners. SO... if it does really high scan rate like more than 128000 dpi you could sell it (if in full working order) for a tidy sum.

If its a fairly recent scanner and 1200dpi is its best and you're pushed for glass, then go ahead, re-purpose the scanner bed.

A glass supplier that has to order in some tempered glass..!?!?!
I have in all the years of having to go to glaziers, never known any glazier to not carry the glass needed for the job...
Question is how much is it costing? $10, $20, $30 as you could likely have gone to a junk / pawn brokers / thrift shop, tossed $5 at the clerk for that old scanner and just ripped the glas bed out of it.

The one I went to here in Carrollton had to order it as well. It seems they do not ground the edges in house and that is what has to be done somewhere else and that is why they have to order it.

Once it reaches I temp I start it cooling. Once it reaches room temp I start it heating and I repeat three times.

my bed heats to 110°C how long do you let it soak before you start cool down?

Tempered glass works just as well and is very reasonable price wise. It is designed for extreme temp changes and stress. Most glass shops carry it and can custom cut and ground the edges for a small fee.
