[QUOTE="J E Custom, post: 1980454, member: 2736"] The plastic bottles are the best containers for powder storage as long as the lids are one tight and sealed. All powders are hygroscopic if left open to the air. If the seal is not good they will degrade and become acidic. Powders have a controlled moisture content and it should be protected as much as possible by proper storage at a constant temperature if possible. the plastic containers don't wick moisture so even when using, keep them closed as much as possible. Over time powders will degrade because of the existing moisture content but with minimum exposure to air and good storage, it will last many years. J E CUSTOM [/QUOTE]
