Ambrosia Maple peppermill. Worm holes filled with instant tea and ca glue. I was going to try coffee grounds and ran across the instant tea in the cabinet. I thought it would be a little finer grained for the small worm holes. It worked fair the instant tea had to be crushed a little between my fingers to make it a powder. Mill is about 2 1/2" dia x 10". Finish is ca glue. Crush Grind mill mechanism.
