  2. Borosilicate glass - Wikipedia

    en.wikipedia.org/wiki/Borosilicate_glass

    Such glass is subjected to less thermal stress and can withstand temperature differentials without fracturing of about 165 °C (300 °F). [1] It is commonly used for the construction of reagent bottles and flasks, as well as lighting, electronics, and cookware. For many other applications, soda-lime glass is more common.

  3. Tempered glass - Wikipedia

    en.wikipedia.org/wiki/Tempered_glass

    Tempered glass can be made from annealed glass via a thermal tempering process. The glass is placed onto a roller table, taking it through a furnace that heats it well above its transition temperature of 564 °C (1,047 °F) to around 620 °C (1,148 °F). The glass is then rapidly cooled with forced air drafts while the inner portion remains ...

  5. Thermal fracturing in glass - Wikipedia

    en.wikipedia.org/wiki/Thermal_fracturing_in_glass

    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 ...

  6. Thermal shock - Wikipedia

    en.wikipedia.org/wiki/Thermal_shock

    Thermal shock resistance measures can be used for material selection in applications subject to rapid temperature changes. The maximum temperature jump, , sustainable by a material can be defined for strength-controlled models by: [4] [3] = where is the failure stress (which can be yield or fracture stress), is the coefficient of thermal expansion, is the Young's modulus, and is a constant ...

  7. Glass - Wikipedia

    en.wikipedia.org/wiki/Glass

    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 ...

    However, the FOX Forecast Center said that temperatures in Miami are not expected to fall into the 40s during this ongoing arctic blast, so there appears to be no current threat to the lizard-like ...

  9. Heated glass - Wikipedia

    en.wikipedia.org/wiki/Heated_glass

    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).
