For what it is worth...There is another active thread on the forum about dry skin caused by clay, glaze, etc. Biglou made an interesting observation. There are M.D.s on the forum, yet none have given their advise about ecczema, psoriasis, or contact dermatitis therapies as they relate to ceramics.
I am a praticing M.D. who treats these condition on a regular basis. Before I could diagnose I would need to gather a better history, view the lesions and review med usage, etc. The forum may not be the best place to do this.
BUT, It is a great place to take a history of ceramic problems, view pictures of the problem areas, review glaze usage and application, and diagnose/discuss remedies to the problems.
I appeciate and thank the "Clay Doctors" of this forum for sharing wthout restraint.
And your comment about "Before I could diagnose I would need to gather a better history, view the lesions and review med usage, etc. The forum may not be the best place to do this" is precidely why I start so many responses with the "It depends" business that is my trademark in my college classes and also here.
So there is some 'restraint' there.
And just like in the area of medical practice...... a forum like this has severe limitations in "diagnosis and treatment" of ceramic issues. For the "glaze and kiln doctors" you also typically don't get the full history, you can't get a "hands-on" viewpoint on the material or equipment in question, you can't order accurate lab tests yourself, you have no idea of the level of 'technical' understanding of the person with whom you are working, many of the terms we use are 'subjective' in meaning (such as "put the kiln in reduction" versus the numbers you'd get on a crit) and so on. Not much different from the MD's problem with medical related stuff from 'afar', really.
Hence... somtimes.... 'bad' advice on things.
It is also why when it comes to all the health and safetty discussions that crop up... I routinely tend to refer folks to the published "primary source" references in the field...... and tell them 'talk to your doctor'. And for the "is it food safe" stuff......... constantly tend to say 'get it tested and then compare to published standards'.
And why I said earlier in this thread.... "Vet your sources."
I've seen so much stuff published on forums, in magazines, and in books that, at the least, goes 100% contrrary to basic science it is amazing. But it is often politically incorrect to point out that "The Emperor has no clothes".
FYI........ here's the bottom line disclaimer included on the college level class texts on ceramic toxiclocgy I've written:
