Muy apasionada esta zorrita alquimista espero Elle sobreviva a esto. xDDD
Te rifas! =>w<=
I'd be kind of interested in getting ahold of some of those books myself though.
Back in 1882, a German chemist named Otto Schott was interested in experimenting with ways to create glass that had the ability to withstand sudden changes in temperature or exposure to uneven temperatures without shattering. In that year, he made the discovery that ushered in the creation of borosilicate glass. Schott discovered that the addition of the element Boron to the glass fabrication process resulted in a heat-resistant form of glass.
Borosilicate glass is a specialized form of glass that uses boric acid as a component in its fabrication. The result of the addition of the element boron is a type of glass that is very resistant to thermal shock and exhibits a much lower coefficient of thermal expansion than that of common silicate glass.With borosilicate glass, the addition of boric acid (H3BO3) to the formulation results in a glass that has a low coefficient of thermal expansion, which means that when the glass is heated or cooled, it does not expand or contract very much. This dimensional stability is what enables borosilicate glass to be capable of withstanding rapid and extreme temperature changes without cracking. Working temperatures up to 300°C. Talk about alchemy!
The chemical composition of borosilicate glass typically consists of around 81% silicon dioxide (SiO2) and 13% boron trioxide (B2O3) with lesser concentrations of sodium oxide and aluminum oxide. (Note that the concentrations of boric oxide can vary, 5-13% is typical). The element Boron is what provides the glass with its dimensional stability so that the material doesn’t shrink or grow as the temperature to which it is exposed changes.
(And yes, it technically can be made "at home" if you have the furnace for working glass as the working temperature of Borosilicate glass is 525°C.).
Any serious Alchemist worth their Salt, Sulphur and Mercury will have the needed equipment to make replacement glassware, as some experiments will cause containers to "rapidly disassemble" at some critical state. (such as an unexpected runaway exothermic reaction, for example)
Looks like Fun times are ahead for our 'deer' sweet doe Elle.

The high dimensional stability and ability to tolerate exposure to different temperatures at the same time make borosilicate glass a natural material choice from which to create laboratory glassware, also called labware. Petri dishes, microscope slides, bottles, beakers, flasks, test tubes, funnels, and measuring instruments such as graduated cylinders are all common examples. Besides the favorable thermal properties, borosilicate glass is very resistant and non-reactive to most chemicals. Are all needful qualities in the practice of the alchemists art.
