Na Europe, ihe nkedo na-amị amị malitere laa azụ na 1750s, na na China, ọ maliterela azụ karịa. Nkwụsịtụ nke ntụ ntụ seramiiki na-enyere ya aka ịbịakọta ọnụ dị ka mwepu. A na-ejizi ihe e ji amịpụta mee jupụta ebu nwere oghere. Ka ebu ahụ na-akpọnwụ, na-eme akwa oyi akwa si na slips.

NKWUKWU GEL

Ihe nkedo gel bụ usoro imepụta ntụ ntụ nke malitere na Canada na 1960s. A na-eji ya emepụta ụdị seramiiki dị mgbagwoju anya nke siri ike ma dị mma. Na usoro a, a na-ejikọta monomer, cross-linker, na free radical initiator na seramiiki ntụ ntụ. A na-agbakwunye ngwakọta ahụ na nkwusioru mmiri. Iji mee ka ngwakọta ahụ sie ike, ihe nkedo dị ugbu a bụ polymerized. Nchikota ahụ wee ghọọ gel. A na-awụnye ngwakọta gel n'ime ihe ebu ma kwe ka ọ sie ike n'ebe ahụ. Mgbe emesiri ike, a na-ewepụ ihe ahụ site na ebu ma kpoo ya.
