Could you tell us the brand name of the emulsion you used, what sort 
of quantities are available, and its shelf life?

Do you have any indication as to how well the emulsion would stand up 
to other etchants, particularly CuCl? 

Did you have to do anything special to get a smooth coating of the 
emulsion onto the copper?


Regards, Bob
