Keep Satanite on the blade....

I've got a knife I'm trying to re-HT (didn't get quite to critical the first time around) and I can't seem to get the Satanite to stay on the blade. I coat the entire blade with a thin slip coat of satanite to reduce scaling, then put my thicker coat on the spine of the blade. Then into the oven @ 350 for 30-45 minutes. When I pulled the blade out, the thicker layer of satanite is all in one piece, but just slides off of the blade.

Any suggestions as to how to keep my clay on? It worked before, but this is the second time it's done this.

Thanks,

What Ray said. I just got through rehardening a couple blades which I had tried to do without the wire, and failed. So this time I used the wire. The wire I use is Nichrome, which is a high temp material used for heating elements, so it can be reused many times. (It doesn't scale)
 
I don't use wire and do a lot of clay coated quenchs with Satanite. I do wash the blade real good with warm water and 409. I do not put the thin coat on either but just put on my thick coat around 1/8'' -3/16'' at the thickest. I then dry it a bit at the front door of my forge then into the forge and do not bump the clay or it will come off. This has worked very good for me.

409, didn't know that was still made. I'll have to give that a try. So is that how you did the folding dagger blade? I'm still amazed at how great that turned out.

Yep Ray, this is how I did it, I did have to quench twice as the first hamon was not so good. For me 409 works much better than other cleaners.

Here's a photo of the folding dagger.

Preheat the blade and apply borax,reheat till borax melts,let cool,apply clay,no worries.makes the clay stick very well and reduces oxidation during heatreat.:)
 
Same as Don....


I just clean the blade real good (windex or acetone) and apply the satanite to it actually right before I stick it in the forge/oven/etc. (no drying time)

Works great. By the time the heat gets all the way to the blade (through the satanite) it's already "cooked" on the outside. If a crack develops, I just pull it out and goop a little more on to fill it up. Sorry...no voodoo stuff here. Plain and simple. But it works every time without fail.
 
What Don said. That is, put it on clean and pretty wet, then dry it lightly in front of the forge, or with a small torch. Don't dry it so much that it cracks off.
