I have recently moved in some Ash slabs that were air drying for about a year. They were cut 3 inches thick and were doing well air drying. I brought them indoors into the garage to dry them a little quicker. They were around 21% MC when I brought them in. I’m notocing some cracks/splits starting to appear, below are some pictures. Is this a result of stress from drying too quickly? I’m curious what’s causing this and how to prevent it in the future.
