Phase: soft cheese altering and building (additive)
Processes Supported:
- changing the form’s shape
- adding onto the form
- other additions (handles, knobs)
- texturing surface
Things to Remember:
- slip and score all joinings
- compress joints with a metal rib or wooden tool
- perform any bending of the walls or altering of curves
Phase: hard cheese trimming and refining (subtractive)
Processes Supported:
- trimming
- rasping away areas of form
- cutting away clay
- carving patterns
Things to Remember:
- basic form should not be altered
- perform subtractive processes to lighten form or add aesthetic elements
Phase: hard cheese trimming and refining (subtractive)
Processes Supported:
- trimming
- rasping away areas of form
- cutting away clay
- carving patterns
Things to Remember:
- basic form should not be altered
- perform subtractive processes to lighten form or add aesthetic elements
Phase: stale cheese dry shaping (subtractive)
Processes Supported:
- clean surface up
- lighten form further
- soften edges
- trimming or scraping with rib
Things to Remember:
- just before the piece is bone dry, it responds very well to having its surface scraped or trimmed
- if the work has become bone dry, you can sponge it down to do some of these processes
Phase: bone dry erosive action (subtractive)
Processes Supported:
- sponging
- some light carving
Things to Remember:
- sponging the form down reduces sanding, erases unwanted marks, and softens edges
- don’t add too much water!
