These are the second batch of cups I have worked on in the series. These are porcelain with under glaze. I thought it would be interesting to show you what a cup looks like before it is bisque fired - you see, these are still just raw dry clay (no firing has been done at this stage in the process).
The raise relief detail is called slip trailing. This is a liquefied clay that is applied much like a icing on a cake. The color you see is called under glaze which is a glaze that will appear under the more translucent glaze applied after the bisque fire.
