Much tougher and thicker than satanite.<br />
<br />
This morning I removed the refractory on rockwool test sample from its zip lock bag.&nbsp; The bottom side is smooth from resting on the paper.<br />
<br />
Its easier to cure the concrete in a zip lock bag with a tablespoon or two of water then the larger chamber I was using.<br />
