So your initial proposal is something like this:

  Clay Products
  |-Ceramic Technology
     |
     |-Pottery
     |-Space Age Ceramics
  |-Ceramic Art
     |
     |-Hand Built
     |-Wheel Thrown

Other areas I've been concerned about:
 industrial clay/ceramics products
 clay/ceramic techniques and methods
 cultural clay/ceramic history
 technical clay/ceramic history
 clay related tools and ingredients
 well known clay artisens

And I'm sure there are plenty more.  A list of all the existing clay related articles would be a good beginning.  Comments welcome.   02:29, 24 Jun 2005 (UTC)
