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.
Borosil primarily manufactures laboratory glassware [4] and microwavable kitchenware in India. It was established in 1962 in collaboration with Corning Glass Works . [ 5 ] In 1988, Corning divested its shareholding to the current Indian promoters.

Crude versions of conically tapered ground glass joints have been made for quite a while, [1] particularly for stoppers for glass bottles and retorts.

Catalytic hydrogenation in a Fisher-Porter tube. A Fisher-Porter tube or Fisher-Porter vessel is a glass pressure vessel used in the chemical laboratory. The reaction vessel consists of a lipped heavy-wall borosilicate glass tube and a lid made from stainless steel.
Gothic châsse; 1185–1200; champlevé enamel over copper gilded; height: 17.7 cm (7.0 in), width: 17.4 cm (6.9 in), depth: 10.1 cm (4.0 in). Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F).
Glass bottles and glass jars are found in many households worldwide. The first glass bottles were produced in Mesopotamia around 1500 B.C., and in the Roman Empire in around 1 AD. [1] America's glass bottle and glass jar industry was born in the early 1600s, when settlers in Jamestown built the first glass-melting furnace.
