    Mason jars to store dry chemicals?

    I have acquired a sizeable amount of metol, hydroquinone, and potassium bromide, shipped in bags. I would like to store them in airtight containers. Anyone care to comment on using mason jars for this purpose? I don't think the containers need to be dark, do they?

    Mason jars should be fine, but Kilner jars with a rubber seal and spring lock might be better.

    I've used them for this duty and used a vacuum sealer to draw the air out and seal the jars. Seemed to work very well.

    I use this for some chemicals - I fill them up to slightly overfull (yes a bit of spillage) and then put cling wrap/Saran wrap on the top and screw down the lid fully. Works for me and they stay on a bottom cabinet where it is nice and dark. If you really need it dark (and you might, since I mainly keep fixer in mine), spray paint them black.
    Once a photographer is convinced that the camera can lie and that, strictly speaking, the vast majority of photographs are "camera lies," inasmuch as they tell only part of a story or tell it in a distorted form, half the battle is won. Once he has conceded that photography is not a "naturalistic" medium of rendition and that striving for "naturalism" in a photograph is futile, he can turn his attention to using a camera to make more effective pictures.

    As I remember, wasn't The Mason Jar the college newspaper of George Mason University?

    I have used them for many years and as a chemist can say they work very well. No need for Saran wrap which could actually interfere with an air tight seal.

    I remeber reading that it is perferable to use a dark tinted glass containter to protect the contents from light and keep them in a cool dark place. Do they make dark colored Mason Jars?

    About the only photo-chemistry which might be light sensitive are developers, and some of their components, and sensitizers. keep these in a cabinet with a door on it and you don't need to worry about the color of the glass.

    PET plastic (juice, soda, Gatorade, etc) are extremely good and available at your closest trash can for nominal 'cost'. Just wash and dry thoroughly. If chemical is light sensitive, just keep in drawer or cabinet. - David Lyga

    One caution: Mason Jars are used to store food. If you are putting possibly dangerous substances in them, make sure they are clearly marked. I'm talking idiot proof squared. (As soon as you make something idiot proof, they come up with better idiots.) I'm talking labels on the jar and lid and cabinet, tape around the lid, lock on cabinet, etc.
