Josefina Posted October 18, 2012 Report Share Posted October 18, 2012 Hi all, I've been experimenting a lot with underglazes lately. I normally bisque my pots and then apply underglaze which I then fire to the desired temperature of my clay body. I just wanted to know peoples thoughts on whether it is really necessary bisquing an underglaze again and why? Taking the pot straight to temperature seems to work just fine so why do some people say that this is necessary? thanks for your help Link to comment Share on other sites More sharing options...
Chris Campbell Posted October 18, 2012 Report Share Posted October 18, 2012 As always, the answer depends on what you want to do next... ... sometimes the application of a glaze on top of unfired underglazes results in smearing the color since it is not set in place. If you are trying to execute a complicated or involved design it pays to protect all of your hard work by bisque firing before glazing. If you want a pattern all the way around the pot or covering the whole surface and you don't want your hand to drag over it and smear it. You might fire after the first half then do the second half. Another reason that some people bisque between colors is that they need the first color to be fired in so lines stay crisp ... or, think about accidentally getting some blue underglaze on a yellow section and not being able to correct it without re-doing the yellow. Ugh! Another reason could be that you like the first color fired at say, Cone 6 but all the other colors only fired to Cone 04. Link to comment Share on other sites More sharing options...
bciskepottery Posted October 18, 2012 Report Share Posted October 18, 2012 I generally apply underglazes to leatherhard wares and then bisque fire. That allows me to do any touch-ups before glazing, do any layering, etc. I also found, at least in my experience, that the underglazes look better and more uniform when bisqued first, then clear glazed. The glaze will compress your underglaze brushmarks . . . mine seem to be less visible if bisqued first. Link to comment Share on other sites More sharing options...

Marcia Selsor Posted October 21, 2012 Report Share Posted October 21, 2012 I just finished a residency at AIR Vallauris in France and worked much differently than I do in my own studio. I used some ez stroke underglaze and applied to green ware. I liked it. I usually spray underglaze and then do shellac resist in the dry state. I liked the direct application and eliminated the shellac part. It worked well. Will post some pics to the gallery when I get home next week. I am still in France. leaving for Paris tomorrow and a Visit to the Sevres Porcelain Factory museum ..not the Ceramics museum next door.. But may visit there again for fun. marcia Link to comment Share on other sites More sharing options...
