I have a large oak stump in my shop. It was a living tree not two
years ago. It sat outside on its side for a little over a year
before I worked up the courage to roll it (using my car, a logging
chain, a johnson bar, etc.) to my shop 40 yards away and partly
uphill over rough terrain.
It now sits proudly in the center of my shop with a vise and various
other tools attached.
One of the things is a large cake of lead.
I’m now unbolting and removing everything from the top of it so I
can cover it with cowhide and when I lifted the cake of lead I
noticed a fine coating of white powder caked under my cake.
I’m wondering if any of you folks know what it might be. I’m
guessing lead oxide but that implies oxygen and one assumes more
oxygen would brush up against the exposed surfaces rather than the
underneath. And will cowhide make it stop forming?
