The hydrochloric acid I bought is a 36% strength mixture.

The volume of my etching chamber is 2.3 litres

So what I need to know is, what ratio of acid to water would I need to make 2.3 litres @ 15- 20 %

Many thanks.

Thanks for answering this Dennis.

Nailed it.

Not that I know anything about etching stainless.... but, why 18%. Wouldn't 36% etch perhaps twice as fast?

And... pardon me for the dumb question, why are you etching the stainless steel?

The steel is Markus Balach stainless Damascus and so I am going by their recommendations. Also I figured that the lower levels of strength are most likely safer.

Hence I am going for just over the smallest practical volume for my needs at the moment and also erring on the weaker side. Also with the smaller volume I can heat the vessel I am using as the thank (PVC soil pipe with blanking cap) out side in a larger vessel which I can heat.

Its also the first time I have attempted any of this so I might be doing thigs wrong?
