After the BB is made, and it sets out in the open air to cure. Can this curing be done inside an air tight container? Or should it sit out for a couple days before closing up? How much fragrance is lost due to sitting in the open air for curing?
For things with a heat and hold phase, I let containers cool completely before putting a top on so that there isn't condensation (water) added into the product... think lotions and such. That only takes a few hours though... I wouldn't leave them open for days for fear of dust or other contaminants.
