1. Do not use Mason Jars for chemical storage unless you are using plastic lids or caps. Besides glass jars are too easy to break and crack.
2. I have toyed with the problem of chemical storage for some time. I have used any and all types of containers and I have learned the hard way that uniform storage containers is the way to go.

I purchase all my storage containers for my chemicals from USPC, they are inexpensive; plus they provide outstanding service to you when needed.

I use the following storage containers for all my chemicals and reordering extras is a snap.

#66737 32oz/950cc packer jar with 53/400 wide mouth opening @ $00.84 ea.
#66735 16.9oz/500cc packer jar with 53/400 wide mouth opening @ $00.46 ea.
#66339 53/400 caps with liners, for jars listed above @ $00.14 ea.
#66734 8.5oz/250cc packer jar with 45/400 wide mouth opening @ $00.30 ea.
#66156 45/400 caps with liners, for jars listed above @ $00.11 ea.

You can start with a small order and add to it, replacing all your odd and end containers with uniform jars and bottles designed for chemical storage.

Also, USPC have a huge line of plastic labware at very low cost.

I also purchase the following for storing my stock and working solutions.
#66150 32oz round poly-e jugs/ with white cap @ $00.64 ea.

I was able to completely uniform and clean up my chemical storage area for as low as $60.00; over a two month period.
