Four whites: clay body, interior shiny glaze, exterior matte glase and the Namibian rock that tells us that Earth was glaciated about 600 MYA. What I wonder (and search for topics on this including National Geographic's article, is whether it Earth would have appeared as a white marble from NASA's images, like the blue marble we've now come to know. Was it slushy or icey and was it covered with dust? Aqua seaglass thumbwell.
BTW -- fussy clay, unpredictable flow off glaze -- I spend days making 13 and only had 6 usable after I needed to chisel them off the kiln shelves. Therefore the price.
