Terra Sigillata Redart Clay Ceramic Slip new container low fire. NWT This is a special kind of slip made from the finest clay particles, after a thin layer is applied it can then be burnished to a sheen. It also seals the surface somewhat. It was used in old & ancient cultures to seal their low fire ware before glaze development. The most common place to see this used in the United States is on Native American pottery, pit fired, smoke fired & other low fire work, this brand new & sealed quart will last a long time. It is thin & can be applied in 1-3 layers. Non-toxic. See container for directions. I have an other container in white. I’m dissolving most of my professional art studio- I worked in many mediums & you can find a variety of supplies in my listings. And very cool art books. You can add a lightweight item with this - but its 2 1/2 pounds & needs good packaging to ship safely. Not for kids, mostly bc they don’t usually have the careful dexterity it takes to burnish the green (unfired) pottery.
