 Heat resistance test Turn on the drying oven and adjust the temperature to 100℃. Prepare a piece of glass with thickness 2 mm. Put the glass sheets into a 100℃ constant temperature drying oven for 2 hours, then take them out and observe whether there are bubbles or white. Other defects such as bubbles and discoloration shall not occur on the part 15mm beyond the edge or 10mm beyond the crack  Moisture test Instrument: Moisture meter. Cut the sample 5g±0.005g and put into the metal plate of the tester. After the machine finish the determination, the moisture value is read
