i think its beautiful. exceptional natsu chawan.
wow. nice shape !
what i've learned from using some chawan is that porcelain clay bodies tend to conduct heat very well. too good in fact, my hands sometimes get burned.
also, the chawan is grasped with two hands while enjoying the matcha. its nice to have more thickness/balance in the body as 'insulation' if u will. there is a fine balance in thickness versus lightness (balance). at the moment i'm preferring a little thicker so my hands don't get burned. an important factor in the functionality of the matcha chawan.
i'm experimenting w/a double walled thrown and carved forms that would allow for translucency of the clay and safety in handling the chawan.
here is a prototype.
an interesting note about chawan koudai. while looking and learning many years through many museums and handling pieces in friends collections, i've noticed a commonality of a sort of ratio/formula in the design whether the chawan was created intentionally like that or not. the koudai diameter was usually 1/2 the size of the width of the chawan. of course there are variations on this. but many follow this. when i make the koudai, i don't usually measure it, it just comes out like that. if the koudai is too narrow, the profile view looks odd.
in your case, it does have a song dynasty profile and is stunning. it looks translucent too ! very difficult to analyze a photograph without handling the chawan.
is it procelain ?
aloha !
