I have asthma and react badly to mold. I notice that clay mold doesn’t seem to affect me though except in one weird way.
Recently I found mold in a bag I was reluctant to throw away, and did not want to rework it all with bleach or vinegar. I decided to wedge it up and use it anyway. I found that my hands itched as soon as I start wedging it! Gloves solved the problem and as I was making a large slab built piece, that was fine. The interesting bit is that I instantly know when a bit of that clay is amongst other reclaim - my palms itch.
It must be a different strain because I have never reacted to any mold in my clay before. I do try to be careful due to asthma but perhaps have become more complacent over the years.
