My uncle was in town to visit recently. He's a woodworker and I was asking him some questions about what I'd need to turn out pots to begin making my own. I showed him some examples of what I was trying to do, and as a surprise, he went home and turned me out some pots. He even sent me a piece of slate that came off my great grandmother's roof. It's not the greatest sounding, but for sentimental reasons that's going to be my first piece of slate used. It makes pretty good purr and tree yelp sounds. I found a site that sells slates and aluminum, but they also have cork for sale.
So my questions are what is the cork used for, is it a requirement, and how's the best way to seal the slate piece to the pot? Any other suggestions for finishing the pot would be most welcome! I'll try to get some pictures posted later.
