Satanite Refractory Mortar - 5 lb.
Bring out temper lines in your blades or increase the durability of your gas forge with this coating
Satanite has 3200°F temperature rating
Often used to seal gas forge insulation prior to use of ITC-100 .
Satanite refractory mortar is also used as a clay coating for developing "temper lines" (Hamons) on your blades. You can even use hamon clay to coat your entire blade to aid in the reduction of scaling during the heat treating process. Satanite has 3200°F temperature rating
Mix the Satanite to a thick paste...just keep adding water slowly until you get a pasty consistency that you can paint on with a paintbrush....roughly the consistency of sour cream. Spray the ceramic fiber insulation down using water with a hand sprayer to wet it lightly. Next, apply the Satanite to the wool using a paintbrush, covering all exposed wool surfaces. To cure it, you want to dry it slowly. First, let the forge sit for a few hours minimum to air dry a little, then fire up the forge just briefly and shut it down. Do this several times, allowing it to cool down in between and increasing the on-time with each subsequent cycle. You'll see water vapor evaporating the first few times you do this. Finally, fire it up and bring it up to full temp to fully cure it. You will probably want to apply at least two coats of Satanite in this manner...it's a little time consuming (do it over a couple of day period) but makes for a more robust coating. a 1/4" layer is a good thickness to shoot for. If you are going to apply ITC-100 over top of the Satanite, be sure to fully cure the Satanite first.
