a silicone based clay -the back of the blade and the sides get a thick coating , the edge gets a very thin coating , also the smith applies the edge coating in a pattern that when quenched leaves the 'hamon' pattern you find on differentially hardend blades The thicker clay helps the back of the blade cool slower than the thinner clayed edge so the back is softer , the edge harder - soft back = flexibility , hard edge = sharp edge retention.

what is the brown stuff that the man puts on the blade ?

Tempering is different from quenching, it occurs when the blade is reheated after being cooled, retaining most of the hardness while eliminating brittleness. The curve results as a combination of thicker clay on the back of the blade causing that portion to cool more slowly and contract, and the core of the blade being a softer grade of steel with a different thermal expansion/contraction rate.Result is a hard edge but a soft, shatter-resistant body which does not require a tempering process.

The curve of the japanese sword comes from the cooling process. It's got to do with clay & ash.

Are you guys sure this is Jpanaese sword? 'cause I don't think the people in the vid' are speaking Japanese but rather Chinease. So, I'm not sure if they are forging Japanese Katana or Chinese Katana.

actually it depends....it is done both ways. the curvature is gotten by the heating process and also it is deliberate ( hammered untill it curves). it depends on the era that the sword is made. and yes in some eras the sword is strighter then others.
