January 22nd Hint of the Week

More about Wax Resist 

 Partially from The Big Ceramic Store

·         Some people think that waxing the bottom edges of a pot helps keep the glaze from running off the pot. However, the wax burns off way before the glaze ever melts, so this doesn't help. The only purpose of the wax is to make it easier for you to wipe the glaze off, especially when you are “dunking” in glaze.
o   It does help to have an undercut or small break, like a foot, in the surface toward the bottom of the piece. This break will help stop most glaze at that point. But don't depend on it too much. Runny or too thick glaze can still run right over it or your resist.
·         Dip your brushes in soapy water or fabric softener before using wax resist, and the brush will be easier to clean. Good idea to wash them afterwards too.
·         Some people swear by dipping their brushes in Murphy's Oil Soap prior to use.
·         Once you use a brush for wax resist, don't use it for anything else. You might want to paint the ends of all your wax resist brushes a certain color.
·         People having trouble applying wax resist often are using it too thick. Try taking some into a separate container and thinning it with water. It dries faster and may work better.
·         Waxing under or around where lids fit, add alumina to the wax resist, keeps the lid from sticking, and may keep the glaze out if it is not too thick or runny.
·         One way to cover the bottom of a pot quickly and evenly with resist, is to use those cheap sponges on a stick often used for painting. You can get them at the Dollar Store, or pieces of the sponges out of the cone boxes. Unless you use too much pressure squeezing the sponge, you’ll have less excess glaze running down the side of your piece as when using a brush.
o   Like everything else in pottery it will take practice no matter which method you use.
o   Use the technique that works best for you.
