For those who like tea hot, lava hot.
I'm a geology/physics major, and as such, I'm a big fan of rocks - both hot and cool. I tried to use the properties of the basic types of igneous rocks to inspire these teas. If I could play with rocks and drink tea all day, I'd be the happiest tea drinker around!
I'll be taking photos of these in thin section shortly to fill in the blank art!
