Drying phases & Supported Processes

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!
