Варку фритты осуществляют в электропечи при температуре 1400°С. Расплав гранулируют в воду и измельчают до полного прохождения через сетку №0056. Подготавливают глазурную суспензию с влажностью 45-47%.The frits are cooked in an electric furnace at a temperature of 1400 ° C. The melt is granulated into water and ground until it passes through mesh No. 0056. Prepare a glaze suspension with a moisture content of 45-47%.

Готовую глазурную суспензию наносят (напылением, поливом) на поверхность керамической плитки, сушат на воздухе и обжигают в электропечи при температуре 1050°С в течение 30-45 мин.The finished glaze suspension is applied (by spraying, watering) on the surface of a ceramic tile, dried in air and fired in an electric furnace at a temperature of 1050 ° C for 30-45 minutes.
