+1.  this is handled with the material

OK, I think you're right, Tom. We can get users to enter data from a carton;
beyond that, we'd need much more information than is easily available (in
addition to the added complexities of the model).  As far as cotyping
"material" goes, I'm torn -- it has one of the phylogeny patterns we want
already, and I suppose that all ingredients are technically materials, but
the material type seems largely intended for engineering materials (hull
material, etc.), which doesn't seem to be quite the same thing.
