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.
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.
A dark glass bottle with ground glass plug. Reagent bottles, also known as media bottles or graduated bottles, are containers made of glass, plastic, borosilicate or related substances, and topped by special caps or stoppers. They are intended to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves ...
Three beakers, an Erlenmeyer flask, a graduated cylinder and a volumetric flask. Laboratory glassware is a variety of equipment used in scientific work, traditionally made of glass.
Silver is also applied to copper by means of electroplating, and provides an interior finish that is at once smooth, more durable than either tin or nickel, relatively non-stick and extremely thermally efficient. Copper and silver bond extremely well owing to their shared high electro-conductivity. Lining thickness varies widely by maker, but ...
Kitchen utensils in bronze discovered in Pompeii. Illustration by Hercule Catenacci in 1864. Benjamin Thompson noted at the start of the 19th century that kitchen utensils were commonly made of copper, with various efforts made to prevent the copper from reacting with food (particularly its acidic contents) at the temperatures used for cooking, including tinning, enamelling, and varnishing.
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.
By 1917, they sold chemistry sets, which they produced through World War II, in spite of restrictions on materials. Robert Treat Johnson, noting the number of chemistry students at Yale whose interest in the science began with a chemistry set, argued the production of chemistry sets was a "patriotic duty." [5]
