Nitric acid question

[blunderbuss]

  A friend of mine brought me some nitric acid to make stain with I had a wide mouth glass jar so we put it in that, what can I use for a lid? We can rule out cork because it just ate one of those.

What type of stain are you making? Never heard of a stain using sulfuric acid. The only stains I know of use iron + nitric acid or vinegar.

Blunderbus, you probably already know this but I think you need to ad the acid to the water(if you will be using water) instead of the water to the acid. Some one will probably corect me if this is wrong but one sequence will create some trouble if I'm not mistaken. Be safe and best wishes     Smylee

acid into water,, just like you aught to..

water into acid, prepare to be blasted!!

At least that's the phrase our old PHD Chemist/Director always quoted!!!

Use very cold water or even water with a bit of ice in it.  Mixing the two releases heat.

I might add here that when you add (react) the iron in the diluted acid it helps if the container you are using is in a pan with ice and water.  Keeps the mixture from getting too hot.

I would react it in a STONEWARE jar or pitcher.
I like pitchers

If you add just a small amount of iron over time (several days or more) the reaction won't be too wild and it won't build up much heat at all.  This process seems to result in a good iron saturated solution without too much precipitation as well.

Thanks fellows a friend of mine and I did this years ago and he was the one doing it I helped by staying out of the way. We made enough for several weapons but atlas I ran out and have to do it on my own. I thought I knew how but wanted the back up

Thanks again

    I start with 95% acid and cut it to roughly 30%.  I use a l qt glass bottle outside and add steel wool.  I have to pause for a while to let the acid cool before adding more steel wool.  I would be hesitant to put the bottle in a pan of ice water because I suspect that the rapid heat build up in the acid might create enough stress to crack the bottle
