I've been interested in Asian style teapots for a long time. I'm thinking about Tokoname, Arita, Yixing, etc. Many of these have a built in strainer at the opening of the spout like these.
I've always admired the thinness of the clay and the uniformity and precision of the holes.
I've tried making a similar strainer in the past but I have run into problems.
It's hard to make holes this small. I suppose the best tool may be a tube shaped hole punch like the one I use to make colanders but I don't have one that small. I've used a small drill bit but that leaves a somewhat unrefined hole. What can I make a tiny (1/8 inch or smaller ) punch out of? (I need some old ink tubes from ball point pens. I've seen brass ones.)
It's also hard to keep glaze out of the holes if you are glazing. I suppose unglazed wares solve this issue.
How are they made?
Any tips, links, suggestions about making Asian style teapot strainers would be greatly appreciated.
