Protection against firestain on sterling silver


#1

Thanks Leonid,

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.

This saved me lots of troubles.

Thanks

Use a brush or wear disposable gloves long term exposure is not
good. It is a poison.

Let’s try to be a bit realistic. Kitchen salt is the other example
given in this article. Salt is lethal as well, do you wear
respiratory protection and rubber gloves when baking?

Taking the numbers from the article, the LD is 5 to 20 g/kg. That
means 350g (12oz.) to 1400g (50oz.) for me. I might be crazy at
times, but would you imagine someone eating so much boric acid?

Anything is lethal in a high enough dose.

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.
