There are only two things that can cause Cactus Juice to cure, heat and contamination. In a container like that, CJ can cure as low as 85° F. Even if the temp of the shop is not that hot, having a vacuum pump or oven close to the chamber can cause it. Contamination can come from oils in certain species of wood and reactions can occur due to sealed glass containers.
I see a glass container in the picture and even though it was not technically sealed, having it under vacuum for many days is the same as having it sealed. My guess is the glass container started to cure. As Cactus Juice cures, it generates heat which can cause the others to cure as well.
Please send me an e-mail. Even though I know for sure there is nothing wrong with the Cactus Juice, I always take better care of my customers than expected and will help you out on the cost of replacement.
Thanks, I appreciate the offer, but I'm not looking for -or expecting replacement. I just want to understand what caused it. I understand now the the CJ needs to "breath". I find it odd however that the heat from the cured glass jar did not trigger the other glass jar behind it, but triggered the Plastic one which is further away. (that one has the CJ yellow dye by the way) Also the Paper towel at the bottom is soaked with CJ, like it "boiled over". Interesting stuff.
Anyways, Thanks for your reply as I am still learning all the ins and outs. So like you, I am sure the CJ is not the problem but I can't avoid issues I am causing my self if I don't ask the questions.
If, is it OK to use the glass jars while the pump is running, just don't leave it sealed up while not running the vac? Should I avoid the glass all together?
I haven't had any issues to this point with it, but I was away for a few days, and didn't think leaving it under vacuum while away for a long time would be an issue.
Thanks
