To-Be glass jug in transparent borosilicate.
The To-Be jug in transparent borosilicate glass is composed of two adjacent tubes, one blind and one through, of different diameters and heights.
The larger diameter is the container while the smaller diameter is the handle, anchored to the main body. Both tubes are cut diagonally from their central axis to form the beak. The project summarizes the shapes to a minimum, giving the idea of an assembly with the least number of formal interventions.
Borosilicate glass (sometimes also referred to by the trade name of Pyrex) is a robust material, known for its qualities of resistance to thermal shocks and for its low expansion coefficient. It is produced by replacing the alkaline oxides by the boron oxide in the glass lattice of the silica, thus obtaining a glass with a lower expansion. When boron oxide enters the silica lattice, it weakens its structure (due to the presence of trivalent planar boron atoms) and considerably lowers its softening point.
It resists chemicals and is therefore suitable for use in laboratories. It also has excellent characteristics of transparency and robustness, and for this reason it is widely used in the construction of telescopes, lenses, medical and optical instruments, including the components of luminaires, it also has a high resistance to fire, and is used in fire doors. .
Thanks to its workability characteristics, it is now widely used also in gift items and in other applications (for example, containers for specific uses in the kitchen such as those for preparing dark chocolate) which exploit, among other things, the transparency of glass to make the more functional the tool. Particularly suitable for food use, borosilicate glass can in fact be used (although in the instruction booklets of some objects this is not recommended) in freezers, traditional ovens and microwave ovens.
In the pressurized water nuclear reactor, a glass with 12.5% boron sheathed externally and internally in stainless steel as a burnable poison is used, made in bundles grouped in clusters that are anchored to the upper end of the fuel bundle.
