Mmepụta
United States bụ ndị kasị ukwuu n'ụwa na-emepụta na ndị na-eji perlite. Mba ndị ọzọ na-eduga na-emepụta perlite gụnyere China, Greece, Japan, Hungary, Armenia, Italy, Mexico, Philippines na Turkey. Ị nwere ike ịmata ya dị ka obere okwute ọcha ndị a na-eji eme ihe n'ime ala iji kwalite ikuku na njigide mmiri.

Mgbe a gwuchara ya, a na-ekpo ọkụ perlite ruo ihe dịka 1,600 ° F (871 Celsius C), nke na-eme ka mmiri dị n'ime ya na-ekupụ ma mepụta ọtụtụ obere afụ nke na-aza maka njirimara anụ ahụ pụrụ iche nke ịnweta. A na-emepụta ihe mkpuchi nke perlite n'ụdị granular yana ụdị ntụ ntụ, ma ụfọdụ ndị na-emepụta na-ejikọta ya na gypsum ma ọ bụ ihe ndị ọzọ iji mee ka ọ ghọọ osisi mkpuchi. Na mgbakwunye na iji ya dị ka ihe mkpuchi n'ime ụlọ, a na-eji perlite eme ihe maka mkpuchi nke akụrụngwa na-ekpo ọkụ, dị ka ebe nchekwa oyi na-ekpo ọkụ na tankị cryogenic, yana ngwa nhazi nri.
