I love hiking in California's Sierra Nevada mountains: the granite itself is beautiful, shiny, a sparkling kaleidoscope of color that merges to gray at the scale of a landscape photo. This cup reminds me of granite up close, sparkly with colorful inclusions and fine crystalline appearance, but unlike granite, it is softly rounded and feels wonderfully gentle in my hand. Today it was baptized with Den's Sencha Shin-ryoku and then helped with a tasting of Lao Ban Zhang this evening.
I did gain some new insight today into the value of handles, when I filled the green/white yunomi at the office with freshly infused Tie Guan Yin brewed at about 185 degrees. I had better results iwth the Lao Ban Zhang puerh this evening, despite infusing it hotter, by the simple expedient of not filling the cup. Easy to do with the small infusions of gong fu. No more burning fingers!

different side, different lighting, still beautiful

It is a bit larger than the other blue/green/white yunomi, probably large enough to serve as chawan for matcha, if and when I'm ready to try that again.
I will continue to enjoy some teas in my glass cups especially to enjoy the color of the tea, and the small matched cups for comparative tasting sessions, but expect these to be my best companions on many tea drinking adventures from now on.
