you should adjust formula first inorder to reduce % of Zirconium in formula and using opaque frit intead of Zirconium and feldspar or TR-frit and you have to change supplier because some supplier sell Zirconium higher price than others. For Opacifier have only Zirconium, SnO2, TiO2 but two of them is very expensive then we have to use Zirconium
