For more background information on natural plasters, we recommend The Natural Plaster Book by Guelberth & Chiras.

For more technical information about plaster on straw bales (and a fine discussion of other technical straw bale issues), see Design of Straw Bale Buildings by Bruce King.

For an in-depth education in natural plasters, we recommend taking a workshop with Bill & Athena Steen, such as their week-long “Artistry in Clay & Lime”

To see samples of American Clay plaster (and lots of other wonderful green building materials), visit Olive Branch Green Building Supply in North Park, San Diego.
