Found this little porcelian insulator at an antique shop last weekend. It was covered in light yellow paint. I purchased it basically because it looks like an unusual one compared to others I see. I normally don't buy porcelians even though I do have quite the collection of them. Anyhow, this one turned out to have some great colored glazes beteath the paint. It looks like black icing over a nice lighter chocolate color. Anyone know the U number of this little guy? It is 3 1/2 inches tall and 2 1/4 inches across the base. It has no identification marking at all.
