연리문 도자기 접시 만들기 : Making plates with Colored Clay [ONDO STUDIO] 

Your comment makes me keep going! Thank you:)

Well, sorta. I like the idea and these plates look amazing.

The slip should stop the air trapping!

As the strips of clay were being rolled out on the cloth, there were quite a few air pockets visible! I probably wouldn’t try this method as there’s too much risk of the final piece cracking

There was a reason, although you could do it multiple ways. (ex: wax resist, pouring or brushing onto just one side) He wiped the glaze off from the bottom of the plate so that it stayed raw clay, but left clear on top. This presumably was to keep it from sticking to the kiln shelf. But he may have wanted it bare for other reasons. I couldn't say. Personally, though, I would have left the clear glaze over the whole piece and just fired it on stiltz.

Hola. No soy un hablante nativo de Español. Sobre el proceso de glaseado en este video. El alfarero quitó el esmalte solo del fondo de sus platos. Esto probablemente fue para evitar que se pegaran al estante del horno. Esperemos que esta traducción tenga sentido.

가마 내화판에 접하는 그릇의 굽닦는거랑 같다고 보면 되지요.

It's a glaze :) Pottery is finished by applying glaze to the surface and firing it in a kiln.
