Subject: [Homebrew_PCBs] FeCl3 storage
> Hi all,
>
> I had a minor disaster recently when a glass jar I'd been using for 15
> years to store some of my precious dwindling stock of anhydrous FeCl3
> developed a crack. It went unnoticed and as the deliquescent crystals
> absorbed water from the air the etchant liquified and ran all over the
> place causing great domestic disharmony (to put it mildly). Fortunately
> there was not much in the jar at the time.

> I'm down to my last half kilo of the stuff, which I've been using for the
> last 40 years. Ferric chloride is now impossible to obtain down here in
> solid form and yes, I know I'll eventually have to go to another system.
> I've already run some experiments with HCl/H2O2 but that's not what this
> post is about.

> My question is, how best to store it? My last stock is in a sealed plastic
> bag but I don't really trust it. Does FeCl3 attach glass slowly?? The old
> jar looked rather corroded where it broke but had always looked fine up to
> now. Big glass jars are getting hard to find now too. I'm tempted to scour
> the supermarket for anything in a suitable jar with a plastic lid.

> Oh, and if anyone knows where I can get a kilo or two of solid FeCl3
