Subject: [Homebrew_PCBs] FeCl3 storage


> Hi all,

> I had a minor disaster recently when a glass jar I'd been using for 15

> 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

> My question is, how best to store it? My last stock is in a sealed plastic
