Hello everyone

I had purchased a 1906 Edison standard phonograph a few months ago, along with 9 cylinders, 3 of which are black wax Gold Mould cylinders

Just this afternoon, when I took out one of the black wax cylinders to play, I noticed a hairline crack starting at the lip and running 1/3-1/2 of the way through. Any advice for repairing/stabilizing the crack? (Photo for reference, and fingers to better show length)
