I started pottery a bit over a year ago and recently begun exploring decorative techniques.
I tried some underglaze inlay on a greenware piece, carving out decorative lines on a small waxed porcelain cup, then painting the whole thing with blue underglaze, and wiping off the excess underglaze. I bisque fired the piece, then dipped it in transparent glaze and fired it again. The final cup has streaky underglaze, I don't understand why since the underglaze was bisque fired before I applied the final glaze? (I'll attach a picture, please note it's just a test piece
I do notice however that the streaking seems to occur on those lines that were less deep (the straight lines were carved a bit deeper into the clay, might that be the solution? - I thought mishima could be fairly superficial, am I wrong?)
Should I try to sponge on the clear glaze instead of dipping? Also, I find that dipping gives me a bit of a thick final transparent coating, could I try and brush it on in order to obtain a thinner coating or am I just setting myself up for a huge mess?
I'd very much appreciate some experienced insight on this! Many Thanks in advance!
