Last summer I stored my collodion in a chest freezer that I had converted to
a fridge. I stored the collodion in an ice chest which was then placed in the
freezer to keep down on any vapors. My freezer went out and now I'm
wondering where in the heck I should store any future mixes. My garage
tends to probably get too hot in the summer.
I use to keep the collodin at work in a dorm fridge, but all of the talk last
year about the dangers of keeping it in a small fridge made me change my
mind.

Any suggestions?

Mark,

Buy a large cooler from your local big box. When it gets real hot in the summer, throw some blue ice in it. Or better yet, buy one with a peltier cooling system.

Thanks Quinn, but I am curious about the peltier cooling system. I've looked
around on the net and all I can come up with on peltier cooling is for
computers.

Thanks,

Mark

These are under $40 and are the perfect size. They are awesome in the summer when you are mobile too. Makes for a "veil free" plate with every pour!

Peltier Coolers

Quinn,

When you say that they help with a "veil free" plate, are you saying that keeping the collodion cold is a real benefit...? Or is it the developer that should be kept cold ? (or both ?) I realise that hot weather is definitely a negative when it comes to getting "clean" plates, but I never really thought much about the collodion temp vs. plate veiling, and its always good to learn any new "tricks"...

Greg,

I believe keeping all of the chemistry in a cool, dry and dark place is the best. The life of the Collodion will be shorter in a hot, UV exposed environment. It's sensitive to both. Silver bath will also cause problems when it's hot. You are correct about the veiling issues, 90%+ is caused from overactive (hot) developer without proper formulation adjustments.

The bottom line is that if you could shoot in an ideal, climate controlled environment, you would find that 65 - 70 degrees F with 25 - 30% humidity is premium.
