Dear Dave Finkelnburg,=20
Our main sources of information about the plastic nature of clay seem to =
be the Hamer Dictionary and Lawrence and West's book about ceramic =
science for potters.
These give us the idea that clay is plastic because clay crystals slide =
past each other lubricated by water in the mixture.
Do you know if anything has been added to this view?
Best regards,
Ivor.
