Learn more about condos for sale in St. John in the US Virgin Islands. If a piece of galena has a specific gravity of 7.58, that means that it is 7.58 times heavier than a volume of water identical to the volume of that particular piece of galena. bk-7 optical glass BK7 is a high quality optical glass that is used whenever the additional benefits of fused silica are not required. St. Thomas Office. If a piece of galena has a specific gravity of 7.58, that means that it is 7.58 times heavier than a volume of water identical to the volume of that particular piece of galena. Other thermal properties of borosilicate glass include the following: Annealing temperature = 470 - 640°C; Vicat softening temperature = 460 - 840°C This means that to shatter a 1cm cube of glass, it requires a load of some 10 tonnes. Surface flaws can drastically reduce the inherent strength of any glass, so tensile properties are greatly influenced by these defects. Other thermal properties of borosilicate glass include the following: Annealing temperature = 470 - 640°C; Vicat softening temperature = 460 - 840°C Surface flaws can drastically reduce the inherent strength of any glass, so tensile properties are greatly influenced by these defects.
