Many ceramicists are familiar with glazing and glossy fired surface treatments, but in this 3 week workshop, students will be introduced to the colorful world of terra sigallata and how it can be incorporated into raku firing to produce silky matte surfaces and unique sheens when burnished. The class will discuss the history of terra sigallata and how it served as one of the very first water tight sealants used on ancient pottery.

Students will throw on the wheel for the first 2 classes, with the last class for firing and cleaning up the finished pots.

Additionally, the class will make a batch of sig together which will be distributed on the last day for student to use in their future classes. A select number of mason stains will be offered for students to color their sig with. The class will end with a raku firing on the final day where students will select from a variety of "naked" raku surface finishes that work together with the sig application.
