Glass annealing tester
WebAnnealing Means cooling the glass slowly enough to be sure the temperature all through the glass stays almost equal while cooling. This gets tricky because glass is very slow to take on or give up heat. The … WebThis standard establishes scratch test and temper specifications for the proper annealing of glass containers used for candles, as well as thermal shock differential requirements.

Webthe glass always looses heat from its surfaces due to convection and radiation. The center part of the glass is always at a higher temperature than the outer surfaces during cooling. Therefore at the beginning of the cooling (t4) a temperature distribution is introduced in the glass that depends on the annealing rate and size of the glass part. WebMay 4, 2016 · To study the effect of partly crystallization, three annealing temperatures 360, 400, and 480 °C were selected. The samples were heated, respectively, at a heating rate of 10 °C/min, and kept at the temperature for 2 h, then taken out …
