Its mean specific heat capacity at constant pressure (20–100 °C) is 0.83 J/(g⋅K), roughly one fifth of water's. [9] The temperature differential that borosilicate glass can withstand before fracturing is about 330 °F (180 °C), whereas soda–lime glass can withstand only about a 100 °F (55 °C) change in temperature.

This technology uses a special metallic coating on the surface of the glass invisible to the naked human eye. [2] A pane of heated glass can achieve temperatures up to 350 degrees Fahrenheit (177 degrees Celsius). The standard desirable temperature range in buildings is between 104 and 113 degrees Fahrenheit (40 to 44 degrees Celsius).
Glass is an important material in scientific laboratories for the manufacture of experimental apparatus because it is relatively cheap, readily formed into required shapes for experiment, easy to keep clean, can withstand heat and cold treatment, is generally non-reactive with many reagents, and its transparency allows for the observation of ...
Borosilicate glass is a type of transparent glass that is composed of boron oxide and silica, its main feature is a low coefficient of thermal expansion making it more resistant to thermal shock than most other glasses. [10] Quartz glass can withstand very high temperatures and is transparent in certain parts of the electromagnetic spectrum.
But storing water in a fridge helps prolong its freshness, compared to letting it stay at room temperature or near heat, which increases the chances of bacteria growing in your water.
Solar absorption: the temperature of glass depends on the amount of heat absorbed by the glass. So a high performance solar control glass will absorb more heat. so it will be more prone to thermal fracture; Shadow: the presence of shadows will result in relatively cooler areas in glass. Thus it results in temperature difference and may result ...
An example is when glass is heated up to a high temperature and then quickly quenched in cold water. As the temperature of the glass falls rapidly, stresses are induced and causes fractures in the body of the glass which can be seen as cracks or even shattering in some cases.
