Ceramic Resin Storage

Hi All,

After resting for awhile, the ceramic resin starts to phase separate - this is normal and we just need to re-stir as directed by the printer. However, I have noticed that the (yellow?) liquid starts to creep under the film of the Tank and makes a bubble. I can squeeze this liquid back out using the spatula, but is now orange. I have ordered a new Tank but wondering if this is a regular thing? If I leave the resin stand am I degrading the tank? How should I store the ceramic resin if this is the case? Furthermore, storage of this resin in the Tank ended up drying/shattering the black tank cover and degraded the cardboard box the Tank came in.
