Taxidermist friend of mine is having a huge Mold problem in his shop and can not figure it out. You can take a freshly tanned cape and mount it and with in two days it starts to mold (the mount is under a bag to dry slower). The Mold is black and takes the mount over fast but nothing else in the shop shows signs of Mold. I have had my comp mounts under a bag for weeks with out getting even a musty smell but he can't go 48-72 hours before Mold starts to grow. He just moved into this building earlier this summer and didn't have this issue at the other location. The shop is clean and not damp or wet and shows no signs of mold anywhere. Any idea's as to what to tell him to change, look for or check???
