Webb17 nov. 2024 · The oldest glasses (Early Gothic glasses from the third quarter of the 13th century) found in Bohemia were made by melting of two main ingredients – sand/quartz and wood ash [ 7, 8 ]. However, it is not completely clear whether those glasses were made in Bohemia or imported from other production areas (e.g. Germany). WebbThe density of glass varies with each type and ranges from 2000 to 8000 kg/m 3 (for comparison, from less dense than aluminum to more dense than iron) at standard conditions. Flint glass can be so much denser than crown glass because flint glass contains lead, which is a very dense element. Shaye Storm -- 2004.

"Webb6 okt. 2015 · The strength of a material is the amount of stress that it can withstand before fracturing. For a perfect theoretical glass, the strength is defined as. where γf is the energy of the fractured surface, Y is Young’s modulus, and a0 is the distance between atoms in the glass. This typically ends up being on the order of GPa (gigapascals (109 Pa). " - Theoretical glass

Glass typically has a tensile strength of 7 megapascals (1,000 psi). However, the theoretical upper bound on its strength is orders of magnitude higher: 17 gigapascals (2,500,000 psi). This high value is due to the strong chemical Si–O bonds of silicon dioxide. Imperfections of the glass, such as bubbles, and in particular surface flaws, such as scratches, have a great effect on the strength of glass and decrease it even more than for other brittle materials.
