Re: your email It is easy to support a good idea.
I'm interested in what you come up with on additive A. Some time ago I posted a message on the board asking if anyone had tried it. Of course, nobody had but many posted irrelevant comments.
I too like to solve the problems, but more from the mechanical end than the chemical end. That is a reason that I call myself the gizmo guy. Also being a welder helps me make strange gizmos to make pottery easier.
