Derek,
Thank you, the honey colour of the wood and the wide growth rings make me thing it's cherry, or one of the cherries anyway.
John,
Thank you, I'm getting better at these forms (slowly), but it is the ceramic/glass effect I have really mastered and want to portray in these pieces.
You had me there for a moment, I had not noticed any demarcation line, certainly not when colouring it and not when looking at it. but yes, you can see it in the photos. I know the effect but it took some work digging through my strange collection of books to find out it's called a 'cylindrical anamorphosis effect'. What you can see is the round edge of the table the form was sat on, it follows the curve but if you look again, it curls up and over itself at the extremes of each side.
