What is clay quenching? Do you coat with clay then fire it? Or do you actually quench it in clay instead of oil?

From what I understand, the blade is covered in clay, with less on the edge than the rest, then heated to x degrees/color and quenched normally (i.e. oil or water). SOme portion of this is what creates the differential hardening effect and that lovely hamon. Or something. One of our fine smiths will explain (they've already done in a few other threads, but I'm in no place to go look them up right now) better than me.

go to Bob Engnath's Legacy site and click on the "Manual" button. It will tell you all you want to know. You can check out his specific page for applying clay here: Clay

first you apply clay to the back of the blade, and not to the edge, and you fire it. When you quench it, the edge will harden much faster, making it harder. The back will not cool so quickly and will be softer because of it. This also produces sori(curvature) in longer blades.
