I-Agate luhlobo lwe-silica ye-microcrystalline, ikakhulu i-chalcedony, ephawulwa bubuhle bayo beenkozo kunye nokuqaqamba kombala.Ukucoceka okuphezulu kwendalo ye-agate yaseBrazil (97.26% SiO2) iibhola zemidiya ezisilayo, ezikwazi ukunxiba kakhulu kwaye zixhathisa i-acids (ngaphandle kwe-HF) kunye ne-solvent, ezi bhola zisetyenziswa nanini na xa ubungakanani obuncinci beesampulu kufuneka zigaywe ngaphandle kokungcola.Ubungakanani obahlukeneyo beebhola zokusila ze-agate ezikhoyo: 3mm ukuya kwi-30mm.Iibhola zeendaba zokugaya zisetyenziswe ngokubanzi kwiinkalo zeCeramics, i-Electronics, iShishini lokuKhanya, iMithi, ukutya, iGeology, ubuNjineli beMichiza kunye nokunye.
