How can you make glass heat resistant?
Heat the glass in a tempering oven, either in a batch or a continuous feed. In order to temper glass correctly, the oven temperature must be more than 600 degrees Celsius (1,112 degrees Fahrenheit). The industry standard is 620 degrees Celsius (1,148 degrees Fahrenheit). Quench the glass to cool it.
What temperature can mason jars withstand?
What Temperature Can Mason Jars Withstand? When a mason jar is boiled, it reaches temperatures of up to 212 degrees Fahrenheit (which is the boiling temperature for water). Other methods of sterilization, like pressure canning, expose the jars to temperatures up to 250 degrees Fahrenheit.
