Representative perlite bulk rock samples from two areas of Milos Island, Greece were collected and the expansion properties of their industrial product were investigated. Coarse crude perlite from Tsigrado exhibits better expansibility, which is assigned to the presence of coarser crystallites in its bulk parent rock. During thermal treatment, the finer crystallites of the coarse crude perlite ...

THE EXPANSION PROCESS. Perlite ore is a dense glassy volcanic rock closely related to pumice, but differs principally in its combined water content, which allows perlite ore to be "popped"—expanded up to 20 times its original volume when exposed to rapid, controlled heating. Super-heating perlite ore to 1,700°F softens the volcanic glass ...
