Liver of Sulphur question

[Toni Lutman]

Hi,

I want to get an electroforming setup and will want Liver of Sulphur. I've seen that it comes in liquid form and in chunks that can be dissolved. Is it dissolved in water? Which is better, liquid or the chunks? How long does it last?

Thanks

I use the chunks. For the size work that I do, the chunk size (that comes from Rio) is too big and I am wasting it. Yes, the chunks disolve in water and the solution keeps it's ability to work for about a week. A solution that is warm/hot works better and faster.

The chunks come in little plastic bags and you MUST keep them tightly sealed while in storage. I have the chunks sealed in the bags and the bags are sealed in a glass jar with a screw top, but still a whole bag full of chunks went bad and no longer work.

Anyone have any experience with the liquid form? Does it go bad quickly?
