what started out as a topic of a chinese term has lead to use of artificial glues or plastics "plastic balls", i have had these teas and have had pearl/ball teas which are shaped by compressing before tea has completely dried. i think if glues or plastics were used they would be visible/cloudy and also have a taste or odor....
-icetea some other terms are flowering tea, Rosette Tea or wheel tea flowering tea seems to get the most hits (29,500), guess its the most used translation
