We have tested over 40 refractories found this to be the best compromise between insulation and castability.
Kastolite 50-25 Plus is a 2500°F rated, lightweight insulating refractory.
Insulating refractory does not absorb heat like heavier refractory.
- Includes 5 lbs of material, more than enough to cast a new chamber for an Atlas forge.
- Requires 24 hours to chemically cure
- We recommended baking in the oven for 5 hours @ 400°F to remove moisture.
- May also be air dried for 2 days with a fan blowing on it.
