If you are easily offended don't look!

The really hard part is dealing with your first serious caustic burn and the skin grafts you’ll need.

I still have a 1/2” deep hole in my leg after the repair work

Be very careful.

Very true! I was fortunate to be a trained chemist and had been handling dangerous acids and much worse for years before I took on home bluing. So safety glasses, rubber gloves, overalls and a nearby source of water are a must.

I just got a droplet inside a boot, at 140 degrees the temperature burns the skin and nerves away so the caustic element can burn away for in my case hours with no pain at all....

Later I found a 1/2” deep black hole in my leg

The burns unit apparently amputate a couple of feet a year from concrete inside people’s boots which does the same.

Full PPE and neutralising solution handy every time....

Oooh, Richard that sounds very nasty. At least acids let you know when they are on your skin. I certainly wouldn't like to take on commercial scale hot alkali bluing, and anyone who does deserves every penny they can get.
