Atlas Knife & Tool - Kastolite 50-25 plus – 5lbs

This is our recommended castable refractory for building a forge without wool. 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.
