Kwisifundo sabantwana, bawenza umthi ovela kubahlali, umxhasi wawugutyungelwe luvuko, amanzi, amanzi - ukungqinelana kwe-cream ye-cream emfuneko. Abantwana basafezekisa ukungqinelana okufunekayo, ifakwe kakhulu le gypsum kangangokuba abayifuni ngaphezu kwe-10% yomxube kwi-oxray. I-Gypsim ikhule ngokukhawuleza, ngoko ke yayiyimfuneko yokufumana indawo entsalela yentsalela. Ibhotile yaphakama, yomiswa i-Plaster, kudaka olutsha kuya kuba yimfuneko kwiglue kunye netyuwa, ityiwa, i-chads, i-gypsum yayisele iqabile -
Bapeyinta i-tercolor eqhelekileyo eblowu, emfusa, umbala wolwandle, emva koko ityuwa, iityuwa kunye namaqhuqhuva yayisele inamathele kwiPDA, ipeyinti encinci yesilivere. -
Isakhiwo sinomdla kakhulu.
Mhlawumbi, kuya kuba yimfuneko ukuba iphinde ibuyele kwinxalenye ephezulu, kwaye emva koko oku kudlule ngandlel 'ithile akulunganga.
