Clay Casa's kiln-centered pottery and glass workshops aim to liberate creativity lingering within hands, teaching students how to forge vibrant and functional glass sculptures. During, two-hour Ladies' Night classes, gals use the studio's materials to create a fused-glass project, which the staff fires on-site once it's completed. A complimentary array of light snacks and desserts, coupled with student-brought beverages, fuels burgeoning glass mavens of any age as they learn the art of safely cutting and arranging jewel-toned shards into handcrafted home accouterments, such as a sleek sushi dish or decorative taco shell. Otherwise, duos can tap into their inner Mondrians during a 90-minute Beginning class. They'll choose a blank, preshaped template before culling the colored-glass scraps that will bring their designs to shimmery fruition. Then the atelier's fiery kiln liquefies glass creations to fuse the different pieces together tighter than sailor-tied shoelaces, yielding a cohesive final product, which may include a coaster, jewelry piece, or ornament.
