My original point was allowing the purchase of raw material by outside entities could lead to potential of utilizing the various properties in things you couldnt even imagine. we'll call this 2 heads are better then one. How about public toilet seats? However understand it at the level I do and you've opened up a can of worms here on potential.
Base material doesn't matter on the embodiment sometimes. Ceramic on Ceramic is fine if that's easier and doesn't require a freaking plasma reactor or sintering equipment. Path of least resistance. It's probably such a tightly nit community you would be banned. The word would get out to not answer the phone or contract the job works. However it seems like biofilms would be a concern on issues such as public toilet seats..Social ramifications indicate a low priority in concern of biofilms of certain embodiments. Thus a perceived low demand and low sales.
