At Quari Handcrafted Ice, located in a West Fulton Market neighborhood industrial building, employees do all they can to stop shivering. They are, after all, spending much of their shift in or near a freezer.

"Our mission as a company is to not only bring ice that looks amazing, and is beautiful, crystal clear, perfect edges, but also that performs well," said Neil Sullivan, the co-owner of Quari Handcrafted Ice.

Ice performance? It's a thing. Because even though they use local water, they fill their expensive Clinebell machines with it, then apply a state-of-the-art filtration system, using reverse osmosis and ultraviolet light. The result? Perfectly clear cubes.
