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. The chemical composition of t… Webb16 maj 2001 · The paper discusses the anomalies of the former interpretation of the working mechanism of the ion-selective electrodes.

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.
