When you have a closed casing i see no reason why to use amber glass. Can't i just use clear labglass, with airtight seals, when the box is closed there will be absolutely no light.
Amberglass is only vital if you have your stuff exposed to a lightsource, i suppose.
Because i somehow dislike the inability to see the contents color (white, tan, yellow, brown) with amber and want to stick with 1-3ml clear labglass miniflasks within a sealed box.
I was using largemouth amber glass jars with dessicants and oxygenabsorbers where i put all baggies in before but i wanna move away from that. Once open you have to renew the absorbers and you expose 90% of the material to oxygen all the time while you dont need it.
For testing purposes i have been storing freebases in plastic, glass and amber for 3 years now. the contents of both glass vials look completely identical, the contents of the plastic bag turned brown on the lid of the baggy due to oxidation.
also stability of most commonly available material is overall good even in plastic bags. 3 year old mxe did not loose anything. the only thing that shows signs of decomposition after 3 years is 5-meo-dmt freebase. i also have a small amount of 5-meo-dmt freebase frozen in double sealed amber vials in the freezer. but i wount check its condition after another 5-7 years. might report back then how this little experiment went
about oxygen:
if you store substance as powder in an airtight glass vial, how much does it matter that the vial is not filled up until the lid?
i mean, once the oxygen in there is gone through oxidation it should not matter any further, right? opposed to a plastic baggy that lets oxygen through all the time.
I could not put them in my fridge saddenly but they are placed in the dark in amber glass vials !
Now He doesn't leave it in direct sunlight (duh) but inside a cigarette box in the console or in the glove box and its fine. He has been feeding plants this material since before the 2004 busts. This stuff is pretty stable.
