EKasse 2 Posted March 16 Report Share Posted March 16 Hi everyone - can anyone please help me work out how to paint with underglazes onto bisc ware - how to stop the paint brush from dragging and sticking to the pot? Is there something I can add to the underglazes (i'm using standard ones from ceramic suppliers - like Amaco/Scarva) to help them flow better. Ideally I'm trying to pain very thin lines smoothly. I've got lots of different brushes to help however the dragging and sticking really doesn't help and i'm sure there's various things i could add to help with this but there's so many to choose from i get confused! Can any one help with this please? thanks Ela ps: Am UK based Quote Link to post Share on other sites
Magnolia Mud Research 738 Posted March 16 Report Share Posted March 16 1. add moisture to the bisque surface before brushing on the underglaze. if 1 don't work enough, dilute the underglaze with some water. use brushes that hold a lot of fluid; for fine lines, use brushes that have fine tip and hold a lot of fluid. practice, practice, practice.

Hulk 865 Posted March 16 Report Share Posted March 16 Hi Ela! For smooth thin lines, likely you'll get some detailed responses*, for several regular forum contributors do some very detailed underglaze work. You might try a tool like Xiem precision applicator - a squeeze bulb fitted with a small tube. I do use underglazes, but not for any fine/detailed work - filling chatter marks and carving, and patterns with stencils/tape. I find picking up some water in the brush before picking up a bit of underglaze helps; the water is pulled in by the thirsty clay, and the underglaze can slide quite a bit before grabbing. For small brushed lines, perhaps an oxide wash? Any road, am interested to see what others will offer... *network went down, now it's back! EKasse 1 Quote Link to post Share on other sites
liambesaw 2,920 Posted March 16 Report Share Posted March 16 I've always used underglaze on leather hard work because it's so frustrating to apply on bisque and you can't remove mistakes. I also use a lot of underglaze transfers and they don't really work on bisque. That said, what has worked for me is spraying the surface with a spray bottle until the surface takes about one second to absorb the water, at that point you have a pretty good buffer of moisture to help keep the brush from sticking, but not too much where the underglaze runs or spreads. A pretty fine line, and spraying more sometimes causes it to run afterward. EKasse 1 Quote Link to post Share on other sites
Rebekah Krieger 207 Posted March 25 Report Share Posted March 25 I have found it easier to apply to cheese hard surface vs bisque. The brush on bisque seems to absorb too quickly to get good lines. also, I have seen some do majolicia base before brushwork and it appears to flow better, although I have not tried it.

Callie Beller Diesel 2,707 Posted March 25 Report Share Posted March 25 The Majolica painters I know of tend to have binders in the glaze that keep it from shifting as it’s painted on. Or they spray the glaze surface with laundry starch for the same effect. I don’t know that that would be a good approach for underglaze on bisque though. Quote Link to post Share on other sites
JohnnyK 722 Posted March 25 Report Share Posted March 25 As far as brushes for fine lines on dampened bisque, you might look into the pinstriping brushes that automotive and motorcycle artists use for the fine line painting they do... LeeU 1 Quote Link to post Share on other sites

Some pics below all are painted on bisque, some have background underglaze bisque on first except for the cookie jar which was greenware I believe. These may or may not be fine enough for your use but are all freehand and given more time and patience can be finer in most cases. Good brushes, thin the underglaze as necessary, load your brush and practice. Edited March 27 by Bill Kielb LeeU and Hulk 2 Quote Link to post Share on other sites
