Just wanted to share a little something that people may be interested in. This is a product that we use at work to prevent carbon pick-up during carburization/case hardening. This is applied to surfaces that are to be welded or machined after heat treat to prevent those surfaces from picking up carbon. Obviously this should work the other-way around and prevent de-carburization/scaling. It isn't overly cheap (we buy a lot of it and still pay just under $50/1gal. tub), but it is designed for this application and works well. At some point I will snag an "empty" pail from a garbage can, scrape what I can out, apply it to a blade and show before and after pics. But don't hold your breath on that. If someone wants to try it sooner than I get around to it I thought I should share.
Hey Y'all I had a thought; does quenching a piece in oil prevent as much firescale, or is all the scale formed in the forge, not the quench? Also, does heating a piece in a clay sleeve prevent scale from forming? Thanks and Cheers!
