I'm a mild mannered T&A man, myself and PC or not, I admit to observing any well shaped bottom that occasionally chances by. However I don't obsess or lust in my heart about bowl bottoms and I see no point in pinching one or making much ado about them in general. Your views may vary. :)
I consider a salad bowl's bottom to be a necessary, but unseen part that the rest of the bowl sits on firmly. It should be slightly concave and nicely smooth or it's OK for it to continue the wall's curve and sport one simple decorative incised circle, but no fussy beads. It should know its place and keep it.
IMHO, when a salad bowl's bottom exceeds its outer walls, rim and cavity in elegant appearance and takes more time and care to turn and finish with no evidence of how it was held, the tail is wagging the dog (pun intended). That salad bowl has become a wooden cozy or a cake dome. It's not a bowl anymore and has nothing better to do than to sit upside down on its rim and show off its former bottom.
As I sweat and muse about finely turned and finished bowl bottoms I wonder about adding a tall graceful finial to adorn the ornate top that was once a bottom. I best be sure to carefully turn the old top though. Somebody is sure to turn the cozy over to carefully study and offer a learned critique of its bottom, or is it the top?
How hot was it in Tallahassee today? It was so hot even after I downed a cold one I must have hit the send button instead of the delete. Oh well, Bottoms Up! :)
