processhead That would probably work extremely well.
The situation I found myself in as this was happening was in the packaging of 20-40 5# bags of cure #1 on a Friday night and by Monday they had gained several ounces. The plant could have switched to plastic bags instead of paper, but once it was determined that it was just humidity the QC and R & D folks were happy. A few oz of water in a 2,500# batch apparently didn’t change the final product.
Right. If the cure was in prepackaged, factory-weighed containers, then absorbed moisture would be no problem.
Only when trying to weigh out the cure in small quantities, like for small batches, would you run the risk of not adding enough cure.
