Silica Gel - a filmwasters best friends
« on: November 09, 2011, 04:29:55 AM »
I want to share a story with everyone abou the wonders of sillica gel, those little saches you get in clothes, computer equipment and most packaged goods....


A while ago i purchased 3 tins of Expired Kodak Tri-X 400 film. They were $20aud and the seller sold them as is, becsue he claimed 'they were in my freezer for years and the boxes were rusted'...


A few days ago i decided to test one canister out and see if the film was ok! I defrosted it over night at room temperature and the next day proceeded to open the black tape surrounding the tin. I immediately found heaps of liquid within the seal, and when i opened the tin the black back was soaking in black smelly liquid. I though 'dang the film is gona be soaked and useless...' SO i puled out the roll but to my surprise it was dry! it was tacky to the touch though and i found that winding it onto a canister was impossible as the film seemed to be stuck to itself! Then i pulled out my box of Silica gel(collected over the years from different things). I opened the bulk loader and put it inside a dark bag and filled the bag with about 2 cups of Silica Gel drops. 24 hours later i sealed up the loader and tried again! MAGIC! the film was no longer tacky and rolled out normaly!

developed 2 rolls, perfect! Hope this helps anyone who has flooded their film stock or is silly like me and buys rusty film tins from ebay :)

Fun thing is you can "recharge" the silica gel by putting it in a very low temperature oven for a few hours !

Be careful to check the bag / container as, if it ruptures and the (powder / granular version) contents spill into your camera bag (as has happened to me twice in 35 years - so not a major risk) it is a bugger to clean out and remove from all the nooks and crannies of your camera / lenses.

Or just take a ton of packets and put them in a cloth bag before dumping it in the camera bag...

That is a terrific story, and it's something I'd not thought of before, using it for film.  I have one in my camera bag, and have a few saved up in a gadget drawer from various sources.

Also, if you don't have silica gel and need to desiccate something, I've found that a small beaker with a bit of sodium hydroxide in it, when put in a large zip bag with the item you want to dry will work
