How is it that - because plastic is air permeable - we're to use glass containers for developer, but Kodak ships its liquid developers like HC-110 in plastic bottles and they have a rather long useful shelf life? Is the plastic they are using of a variety that does not have this problem? i.e., Should I keep my old HC-110 bottles and reuse them to hold developers? -- ---------------------------------------------------------------------------- Tim Daneliuk tundra@xxxxxxxxxxxxxx PGP Key: http://www.tundraware.com/PGP/ ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
