Glass blowing is a glass forming technique that involves inflating molten glass into a bubble (or parison), with the aid of a blowpipe (or blow tube). A person who blows glass is called a glassblower.
The work shop can undertake fabrication jobs for special research apparatus when specifications of dimensions and design are provided. No charges for glass wares used for teaching and research. The special work for sponsored projects and consultancies is undertaken on payment basis depending on the nature of the work.
The Glass Blowing Workshop also has the capacity to train technicians in the trade of glass blowing. Sponsored candidates from Govt. Institutions and industries can be trained for this purpose on payment basis which depends upon the period and nature of the training.
Glass is a type of matter. Glass is the name given to any amorphous (non-crystalline) solid that displays a glass transition near its melting point. This is related to the glass transition temperature, which is the temperature where an amorphous solid becomes soft near its melting point or a liquid becomes brittle near its freezing point. Most glass you encounter is silicate glass, which consists mainly of silica or silicon dioxide, SiO2. This is the type of glass you find in windows and drinking glasses. The crystalline form of this mineral is quartz.
Chemical Composition Borosilicate glass is a type of glass with the main glass-forming constituents silica and boron oxide. Borosilicate glasses are known for having very low coefficients of thermal expansion making them resistant to thermal shock, more so than any other common glass.
Borosilicate glass is highly resistant to water, neutral and acidic solutions, concentrated acids and there mixtures as well as to chlorine, bromine, iodine and organic matters. even during extended period of reaction and at temperature above 100˚ C, its chemical resistance exceeds that of most metals and materials.
As the Coefficient of thermal expansion of Borosilicate glass Is low, the thermal stresses under a given temperature gradient are consequently low and the glass can withstand higher temperature gradients and also sudden temperature changes/thermal shocks. In general “Strain Point” should be regarded as the maximum safe operating temperature of borosilicate glass. when heated Above 500˚ C the glass may acquire permanent stresses on cooling.
