haroldshipThese and the tagine are non-porous so unless they are not dried, or there is moisture somewhere else in your cabinet you should not be seeing mold. Mold is pretty serious stuff so it might be best to pull everything out of your cabinet and check for the source of the moisture.
haroldshipin between uses you might want to try treating these like you would a cooler....i.e. putting some crumpled "clean" newspaper in them...that should keep mold and funky smells from forming....like the buying mgr below said ...if you have mold its probably from somewhere else...or it might not actually be mold.
haroldshipI had the same problem with my dutch oven, and the solution that I've found – is to leave a gap between the lid and the bottom, so that the air could circulate.
username02We've found a solution. Thanks for everyone's help. What we do is, we let them dry really well, then we store them with a tiny bit of dry rice. Seems to work.
