Technique of the Week

for the week of October 13, 2019

Sgraffito and Carving

Sgraffito
is a form of decoration made by scratching through a surface to reveal a lower layer of a contrasting color, typically done in plaster or stucco on walls, or in slip on ceramics before firing.
Carving
is the act of using tools to shape something from a material by scraping away portions of that material. The technique can be applied to any material that is solid enough to hold a form even when pieces have been removed from it, and yet soft enough for portions to be scraped away with available tools.
These are very similar so we are addressing them in the same post. Potters are more familiar and more adept at these techniques than most ceramists. However, it is always refreshing to expand our horizons and learn new techniques. It is my understanding that sgraffito is scratching and carving is cutting.
In the first picture we see a plate decorated by painting on black underglaze (or colored clay) and scratching through the black to reveal the white clay underneath. The second picture is done the same way but with a lighter color underglaze which should brighten up when fired.
In this picture we see the artist carving through several layers of color with a loop tool. Each color needs to be applied in several coats in order to have enough thickness to differentiate between the layers.

Here we see a bowl and a container where sgraffito was used to create a design. Note the two colors in each piece.

In these pieces  the carving itself is the design without the addition of color. The bird was obviously carved by an artist. But the piece on the left any of us crafters could do with a little practice and patience.

These pieces were cut all the way through the clay to create an open design.

The open design in these pieces is so they can be lit up. Or you could insert potpourri or maybe have small holes to hold individual flowers or toothpicks or pencils.

Cutouts are done with special cutting tools, some are like cookie cutters, and others are tubes or loops. Also an Exacto knife can be used. Clay must be hard enough to keep its shape but soft enough to cut through without breaking.

Whether carving or doing sgraffito, these techniques are done on greenware. The pieces are  very fragile until after they are fired.

I am a novice at doing this but am willing to have a class session where we play around with it. There is so much to learn and so much to do. We tried a little carving at the MVCT Retreat this August. Also, tried some slip trailing which will be another Technique of the Week post.
