Thanks Hans for the on Edinburgh etch. I use it allthe
time with Ferric Chloride. Once when I was out of citric acid, I
just squeezed the juice of a lemon in the mix and to my delight it
worked just fine. Since then I just use the lemon juice as I always
have lemons on hand. Alma

I am always unsure of this part in instructions. When you say 4
parts Ferricchloride, to one part citric acid, do you mean volume or
weight?One is a liquid and one is a dry powder. I always wonder
about this. Cooking, mixing paint. Maybe it’s me.

Hi Gerald, I use weight and that seems to work for me.

It’s four parts to one by volume of each of the finished solutions.

I have been told by someone whose work I admire a lot that my
comments to Thuy Nguyen have cause the recent lull in Orchid
discussions. If that is true, I am horrified. I will apologize once
again to Thuy for my mean and intentional comments. My only real
issue was Thuy’s definition of quality, but I probably elaborated
more than necessary. As a retired teacher, the last thing that I want
to do is to stymie someone’s ambition. Please let’s put this fashion
jewelry discussion to bed and get on with the lively and open
exchange of questions and answers for which Orchid is known. I have
a lot to learn, in many ways, and not a lot of time in which to do
it. Thuy, I wish you well. Thanks. Rob

In my experience, both are powders.
