Dear John Jensen,

Thank you for your contribution to this discussion.

This is an interesting conclusion but I would like to read that article =3D
before making comment about the experiences of that author.

Given that in most plastic clay prepared for use by potters have between =
sixty and seventy percent water by volume, I cannot understand why it =3D
does not dribble out when we squeeze a handful.

It seems reasonable, based on these values, to suppose that between the =3D
flat surfaces of two crystals there will be water equal to twice the =3D
thickness of either crystal. So if I continue my argument to its =3D
ultimate logical absurdity, clay which is aligned with its crystals face =
to face should shrink in length by sixty to seventy percent of the =3D
compression axis as it dries.

Best regard,
