2. Pyrex - Wikipedia

   en.wikipedia.org/wiki/Pyrex

   Older clear-glass Pyrex manufactured by Corning, Arc International's Pyrex products, and Pyrex laboratory glassware are made of borosilicate glass. According to the National Institute of Standards and Technology , borosilicate Pyrex is composed of (as percentage of weight): 4.0% boron , 54.0% oxygen , 2.8% sodium , 1.1% aluminum , 37.7% silicon ...

3. Ground glass joint - Wikipedia

   en.wikipedia.org/wiki/Ground_glass_joint

   Crude versions of conically tapered ground glass joints have been made for quite a while, [1] particularly for stoppers for glass bottles and retorts. [2] Crude glass joints could still be made to seal well by grinding the two parts of a joint against each other using an abrasive grit, but this led to variations between joints and they would not seal well if mated to a different joint.

4. Visions (cookware) - Wikipedia

   en.wikipedia.org/wiki/Visions_(cookware)

   Pyrex, a brand name for break-resistant glass bakeware, has offered complementary brown (Fireside) and Cranberry tinted lines to match Visions colorways in the past. Care must be made to distinguish between Visions and bakeware marketed under the Pyrex brand name, as the thermal properties of each product are quite different.

5. Glass-to-metal seal - Wikipedia

   en.wikipedia.org/wiki/Glass-to-metal_seal

   Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...

6. Borosilicate glass - Wikipedia

   en.wikipedia.org/wiki/Borosilicate_glass

   Guitar slide made of borosilicate glass. Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.

7. Self-sealing fuel tank - Wikipedia

   en.wikipedia.org/wiki/Self-sealing_fuel_tank

   The Henderson Safety Tank Company provided crash-proof self-sealing fuel and oil tanks which were fitted "as standard" to the Miles Master trainer. [2] German aircraft designers used layers of rubber laid over leather hide with a treated fiber inner surface for the self-sealing tanks on the Junkers Ju 88 early in the war. [3]
