Re: ferric oxalate

Oh, lord no. Not for a minute would I attempt to make anything from scratch-- except maybe a pound cake.
No,  I'm just trying to mix up the ferric oxalate powder with distilled water and would like to know the amounts to use-- water to powder, and can you ever heat the water too much?  Just having a hard time here, so wonder if I'm doing something wrong (as usual).

Thanks, Neal.

You are trying to make Ferric Oxalate from scratch?  I've always been told this was a difficult process because of the compound's instability.  There are detailed instructions at http://e.neilsen.home.att.net/FerricOxalate.html   I've read again and again that this was something to buy rather make because of the time it takes and that the relative cost savings is neglible.
Did I misunderstand your question?
