Kast-O-Lite 30 20# with US Domestic USPS priority shipping

This is a High Alumina Castable Refractory with a max working temperature of 3000F. You can cast the entire refractory liner for a forge or just the floor using this material! This material is resistant to flux. This material has a much better thermal conductivity rating than Mizzou castable...a castable forge doesn't have to be expensive to operate!  - 3000 degree temperature rating- Highly flux resistant- Low thermal conductivity = highly insulating compared to Mizzou- Density = 90 lb/ft^3- Mix with water at ratio of 9.9# or 1.2 Gallons per 55#- This material has a thermal conductivity of 4.54 btu-in/hr-F-ft^2 at 2000 degrees F and conducts almost 40% less heat through the forge shell at 2000 degrees F!
