470mm x 470mm Borosilicate Glass Plate/Bed w/Flat Polished Edge for Creality CR-10 Max 3D Printer

I used this on my CRM4 printer, and PETG which I print on all of my printers. This glass just falls apart when the PETG is removed. I use a well known adhesive and all of my other printers release the PETG with no problems. I coated this last piece of glass, (my second one of these) with the same adhesive release agent, and it just ripped the center out of this glass. I don't know what the difference in the molecular structure of this glass but at nearly $100 each it really should hold up as well as all the others. Most of my 19 printers with glass beds have the original glass bed and I print hundreds of parts on them. All release just fine. But this one NEVER releases fine. I just cut my finger on the glass chips stuck on the bottom of the print. Maybe it works for other materials but NOT for PETG.
