This is one of those questions where there is no real definitive
I tend to mix my ferric nitrate until it looks like very strong tea.
Per one quart of water, use 6 level tablespoons. Use only distilled
water and etch the same way I do with the ferric, which are the
little styrofoam pontoons and an aquarium pump taped outside on your
plastic container. This provides the necessary vibration which
keeps the etching process moving. You might see some crystal
buildup, ignore this and just keep etching.
It is important to make sure that what you are etching is very
clean. Grease, soap, etc., just keeps it from etching properly.
I’ll weigh out my ferric nitrate allotment and give you the oz.
