Ngenxa iimpawu zayo isetyenziswa ukwenza i sculpture ngoM encinane. Luhle miniatures, uhlobo yokwenza, iimbasa, isikali yemizobo isixa esikhulu eqingqiweyo, sistucco udini namalungu amancinane eyenziwe udaka ukuhombisa iisilingi. Ngamanye amaxesha iinkosi sebenzisa oku ukwenza amalungu abasebenzi-ngamandla ezinkulu ezenziwe ngodongwe, leyo akunakwenzeka. Udongwe luthe loma ngokukhawuleza, kwaye ukukrola udongwe, kwelinye icala, ukuba ugcina plasticity kunye mninzi yokuqala. Nangona kunjalo, oku kufuneka phantsi pre-unyango. Eziswini, yongeza a plasticizer kunye sombala umbala oyifunayo. Emveni kwezi nkqubo, iza kuba umlinganiselo ukuthamba, kwaye akukho kwahluka ukusuka bumba sculpture lwenziwe kuyo.

Ngokuqhelekileyo, udongwe ziquka fini, iintlobo fillers kunye plasticizers. Ozokerite maxa wambi kusetyenziswa - ekuthiwa-bezimbiwa wax. Kwakhona excipients zezi: olungumgubo udongwe owomileyo, isalfure, talc. Kwiinkulungwane ezidlulileyo ngodongwe walungisa ngokuhlanganisa kwindawo umlinganiselo we-2: 1 rosin wax, amalahle nabo namafutha omnquma. Kakade ke, iintlobo zombala umbala zaye zongezwa. Ekuhambeni kwexesha, ubuchule imveliso kwezinye zokupheka. Zithandwa kakhulu ezi zihlanganisi wax nodongwe, amafutha, isalfure, ozokerite kunye kaolin. Umfanekiso wenza udaka, isimiso, kwakunye naziphi na ezinye. Zinyibilika njengomthwebeba okanye ozokerite, udongwe wongezelela cuba entle okanye isalfure, kunye sakhi, ekukhethwa ukuba ifomu powder. Ubunzima ngenxa ivuselelekile ngocoselelo yaye wathulula maleko ubhityileyo ukuya ezirhwexayo emanzi, kodwa ungasebenzisa kwakhona film polyethylene obukhulu cool.

Ukuba unomdla kulo mbandela, cela indlela sculpt kulo imikrolo udongwe.
