Hydrochloric acid (33%) and NH4NO3.

Could that work in any way?

I could get some conc. H2SO4 without too much trouble, but it's expensive and i've got heaps of HCl here.

Thanks.

This may be of help.

Of all places you didn't search, the nitric acid section! Your question would have been answered!

I *had a look* in the Nitric Acid section, going back 1 year. Didn't see it.

Didn't bother with Chemistry Related either. My Very Bad.

Thanks for the help, and forgiving me....
