Type of glass with high resistance to leaching, suitable to solidify liquid high active waste from nuclear fuel reprocessing. (See 'vitrification')

Glass made from silica and boric oxide. Such glass is highly resistant to chemical corrosion and temperature change (thermal shock) and is particularly suitable for laboratory ware (test tubes, etc.), domestic cooking ware (oven dishes, etc.), high-power lamps and other technical glass ware. It is also used when glass has to be bonded to metal and [..]

Borosilicate glass consists from 80 %  SiO2, 10% B2O3 and around 10% from additional minerals as Al2O3, K2O, CaO, MgO. Borosilicate glass became popular under the brand names "Duran" by the inventor Otto Schott and  "Pyrex" by Corning Glass since 1915. Boronsilicate glass has extreme thermal and chemical stabilit [..]

Almost all our quality glass bongs, chillums, adapters, glass pipes and glass accessories are made from borosilicate glass (also known as Pyrex), but also some from moulded glass. You can see the following description of borosilicate glass and its durability on Wikipedia (link: http://en.wikipedia.org/wiki/Borosilicate_glass): "Virtually all m [..]

A heat-resistant glass made with the addition of boric oxide.
