  2. Glass disease - Wikipedia

    en.wikipedia.org/wiki/Glass_disease

    Glass disease, also referred to as sick glass or glass illness, is a degradation process of glass that can result in weeping, crizzling, spalling, cracking and fragmentation. [ 1 ] [ 2 ] Glass disease is caused by an inherent instability in the chemical composition of the original glass formula. [ 3 ]

  4. Laboratory safety - Wikipedia

    en.wikipedia.org/wiki/Laboratory_safety

    Hot glass looks like cold glass, so a person must be careful to avoid grabbing hot glassware. Glassware can explode if the exhaust is in any way restricted, so any apparatus should be vented. Glassware can implode under negative pressure

  5. NFPA 704 - Wikipedia

    en.wikipedia.org/wiki/NFPA_704

    Materials (including finely divided suspended solids) that can be ignited under almost all ambient temperature conditions (e.g., acetone, ethanol). Liquids having a flash point below 22.8 °C (73 °F) and having a boiling point at or above 37.8 °C (100 °F) or having a flash point between 22.8 and 37.8 °C (73 and 100 °F).

    ISO 7010 states on all symbols with a first aid cross, that it "may be replaced with another element appropriate to cultural requirements". In countries with a Muslim -majority population, an appropriate symbol is the crescent .

  7. 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 ...

  8. 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 ...

  9. Boiler explosion - Wikipedia

    en.wikipedia.org/wiki/Boiler_explosion

    A steam explosion can occur in any kind of a water heater, where a sufficient amount of energy is delivered and the steam created exceeds the strength of the vessel. When the heat delivery is sufficiently rapid, a localized superheating can occur, resulting in a water hammer destroying the vessel.
