Most of the world doesn't even know what blown glass is. If they do, it's because they once went on a class trip to the aquarium and spotted a glass replica of a jellyfish in the museum store. But does the world care who supplies it with these glass jellyfish? Nope.
There's the one fairly famous glassblower. Dale Chihuly (or just Chihuly, because real artists only need one name) is a modern-day glass-blowing artist who makes inconceivably massive and intricate glass sculptures and designs. The only problem? As we said, there's only one and he's already famous. Will there be room for two famous glass artists? You let us know.
