Holds: 17 fluid ounces (500 ml) Height: 4.75 inches (12 cm) Width: 3.75 inches (8 cm) Material: High-fired Porcelain Microwave: Yes Dishwasher: Yes The continuous wave pattern that runs from base to rim highlights the flowing glazes where colors settle into the valleys and break across the peaks differently on every piece, so no two come out of the kiln the same. Every Hammerly Ceramics piece is made by Curt and his team in his home studio near Denver, Colorado. Each design begins in 3D modeling software, is printed as a physical prototype, and used to create a custom plaster mold system. The HC logo is cast into the bottom of every mug alongside the year in which it was crafted. The cast pieces are then hand-cleaned, fired, glazed, and fired a final time in a computer-controlled gas kiln where the glazes come alive. The result is high-fired, glazed porcelain: strong, non-porous, and built to last.
