Sorry,
Here how to do it.
You must mix a solution of sodium citrate with a solution of ferric chloride. Though adding these chemicals under their solid form into water would probably work as well.
To give you more accurate concentrations I miss the final concentration you want and what raw solution concentration you'll start with. Ferric chloride is used by electronics amateurs, sodium citrate is easily found at the pharmacist, at least here.
Once you'll tell me what you have (solution or solid, concentrations) and what final concentration you need, I'll be able to help.
We can discuss it on- or off-list.
Cheers,
Philippe
