[2] Familial Multiple Lipomatosis can be identified when multiple lipomas occur in multiple family members that span different generations. [2] Some people may have hundreds of lipomas ...
Pressed glass (or pattern glass) [1] is a form of glass made by pressing molten glass into a mold using a plunger. [2] Although hand pressed glass has existed for over 1,000 years, the use of a machine for pressing was first patented by Pittsburgh glass man John P. Bakewell in 1825 to make knobs for furniture.
A bowl made from cast-glass. The two halves are joined together by the weld seam, running down the middle. Glass casting is the process in which glass objects are cast by directing molten glass into a mould where it solidifies. The technique has been used since the 15th century BCE in both Ancient Egypt and Mesopotamia. Modern cast glass is ...
Glass disease, also referred to as sick glass or glass illness, is a degradation process of glass that can result in weeping, crizzling, spalling, cracking and fragmentation. [ 1 ] [ 2 ] Glass disease is caused by an inherent instability in the chemical composition of the original glass formula. [ 3 ]
Tempered glass can be made from annealed glass via a thermal tempering process. The glass is placed onto a roller table, taking it through a furnace that heats it well above its transition temperature of 564 °C (1,047 °F) to around 620 °C (1,148 °F). The glass is then rapidly cooled with forced air drafts while the inner portion remains ...
