ZIG-ZAG PLATES - SAW BOWLS?

Don't know what to call them - they were an exercise in 3-D Phi geometry - the Golden Section & all that...

You've got 18th Century Walnut, 19th Century Olive wood & most importantly, 20 Century oxidised stoneware fired to 1250°C!

Got my hair cut today by Zaki th'Iraqi. Good chap!
