Yesterday I tested Leonid recipe against firestain, a saturated
solution of equal parts of boric acid and borax in distilled water.
It worked great! However it did not solidified immediately on contact
as expected and I had to spread it out by hand. But perhaps it is a
matter of learning the technique.
If you actually read the article it says something about long term
exposure not just eating mouthfuls. Maybe instead of picking it apart
you should just R E A D and comprehend. I was a trained poison
management officer and I see no reason to risk health when simply a
brush will do. Also a retired chef from disney world so yes I did
wear appropriate protection when baking. Not from salt but from
flour as white lung is a serious problem.
I have better things to do than continue this discussion. Reality is
I am going to go eat dinner.
