Bray Patch is a ceramic patching material which is best used for filling cracks and bonding breaks. Although its bonding strength has limits, Bray Patch can be used for attaching appendages. If possible, use gravity to your advantage for increased bonding strength.
We recommend using Bray Patch straight from the bottle. If needed, it can be thinned with water. Since it fires white, we recommend covering with an opaque glaze or a slip if using a transparent glaze. You can also mix your clay body with Bray Patch to make the white color less noticeable.
Bray Patch can be applied to either green or bisque ware and fired to any temperature up to cone 10. It is air sensitive and, once hardened, it cannot be reconstituted. For optimal life, do not leave the lid off longer than needed, clean the lid and bottle lip thoroughly for a good seal, and store the bottle upside down. Freezing will also set Bray Patch, after which it cannot be reconstituted.
We normally do not ship Bray Patch during freezing weather which, in Montana, extends between October and April. When possible, we ask that you plan ahead. If you need Bray Patch shipped during winter we can ship it UPS next day or second day for additional charges. When we ship during freezing weather, however, it is at the customer's risk.

I have used this borrowed from a friend. It does it's bonding or patching well but is difficult to sand so use sparingly. IT will dry up if exposed to air so store upside down as directed. I just received my own bottle and feel secure having it to treat any potential cracks or breaks on my clay bodies.
