[TheForge] Re: food grade coating

Brownell's Oxpho-Blue also contains selenium (which makes it a pain to
get in Canada because Brwonell won't ship it here due to hazard regs
in the US).

I've fooled around with various  blues, used Oxpho-Blue quite a lot.
Never found anything that was resistant to getting wet.

Never tried the method using molten poatssium nitrate.  I've heard
long ago of someone using it for fancy spurs.

It may be too late to say this but Parkerizing or phosphating
(producing a black finish) might be more durable.  Parkerizing involves
manganese, possibly on the toxic list but far less worrisome than
selenium. 



FWIW,
