This is sugar cane. Basically you just bite off a chunk. chew on it a bit until you get some juice out, then spit out the rest. After a cane this size I imagine your mouth would be very soar. This stuff can really do a number on your teeth.
This is a shot of one side of our glaze room equipped with sprayer and some of Andrea's frilly little girly pots (I actually really like her work. It is very well done.)
