Each of three grades of Inferno Glaze refractory coating has a different temperature range and a different glazing temperature, as it is imperative that the coating reach its glazing temperature, as an unglazed coating will not perform properly. After the coating has been glazed, it can be operated at any temperature below its maximum temperature.

Grade Glazing Temperature degrees F Maximum Temperature degrees F
IG-14 1,400 2,200
IG-21 2,100 2,800
IG-27 2,700 3,600

Application Instructions

  • Apply in new or used refractory
  • Supplied as dry powder in 1-, 3-, or 5-gallon cans
  • Mix with tap water
  • Apply with brush or spray
  • Air dry
  • Heat to glazing temperature*
  • Detailed instructions in each can

*In foundry applications, the glazing temperature can be reached by adding the melt to the coated piece of equipment. The heat from the melt will complete the glazing process.
