The 2 best ways I can recommend for your expensive mud is:
Use it to "paint" or coat a twig, or leaf. Coat thin layers of
the pmc to the underneath ONLY of a well veined leaf. Let it dry
between coats. When it has a build up of 5 or so thin layers. Fire
it. It can then be used as an element or by itself. The twig coating
is much the same, except that you may coat all round the surface.
The second idea is to coat a hollow form. The directions that
Barbara Simon offers on the Lapidary Journal website are quite good.
