ageing clay

updated tue 30 sep 97

no particular set or organisms should be expected to be in any given clay; it
depends what it has been exposed to and which of the organisms take to the
environment the clay offers. I suppose clay could be sterilized (irradiated
clay?) and then innoculated with known organisms to find the ideal culture.
I have heard of Japanese potters aging clay for their offspring to use.
Wouldn't one be able to innoculate clay with a sample of a favorite clay, in
order to transmit the organisms from the desirable batch to the newly
innoculated batch? (sortof like a sourdough bread starter).

In a word, YES!

In several words: the batch to which the old clay is added must not have
any microbes that could strongly outcompete the added ones. If the
fresh batch were relatively free of bugs, then this should work VERY
WELL.
