What’s Happening

In this semester’s Intermediate & Advanced Pottery with Anita Griffth, the group is focusing on slip mixing and application techniques. Anita uses our normal studio slips in her demos, but modifies them to lower viscosity, yet retain high clay content. Good slip’s have a specific gravity up there around 1.7 to 1.8.
Small quantities of slip are also tinted in side containers to make more colors available.

OLYMPUS DIGITAL CAMERAAnita, shown left, is preparing various slip colors for class use by mixing incremental amounts of the defloculant Darvan, and then testing fluidity. The intent is to have a thick mixture that still flows readily so that it’s “brushable”.  Slips become too thin and runny if you just add water. It’s best if you start with a  slip that’s thick in the container, which is often the case at CAW. 

Below, Anita demonstrates how to add porcelain slip backgrounds to leatherhard greenware at the banding wheel. While the porcelain is still wet, leaves can be impressed, and a contrasting slip added. When the leaves are later removed, a detailed impression of the veins and delicate contours remains ! Further below, a porcelain floral design – added with a slip trailer (left), and sgrafitto with slip trailing (right).

In an application onto wet stoneware, Anita threw a plate and immediately created an impromptu floral design, demonstrating the impact that quick brush work and multiple colors can have. The pink bulbs are the studio porcelain shaded with red iron oxide; the chocolate slip is our “David Frank Black” – which is brown in the container . Both are available on the room divider wall.

Anita’s class meets Thursday mornings from 9 am to 12 noon. There is a practice session immediately afterward, noon to 3 PM.
