I have been told that Tri-ess from whom I previously purchased
Ferric Nitrate crystals is no longer in business.
Can you suggest possible sources for the Ferric Nitrate Crystals?
Also, What proportion of crystals to water is best for etching? I
know about adding the crystals to the water,but don’t know how much
to use. For example how much crystal should I add to 16 oz. of water
to make a solution which will give me a good etch. on silver?
I have worked with Ferric Nitrate,but was using it in liquid form
(ready mixed). However, I prefer to get the crystals and mix up
batches when needed
Thanks for your help. Alma Rands
