My Maple Leaf mugs are handmade on my potters wheel, they are made similar to my Mystery Mugs, the clay has a mind of its own, so the mugs will be One-of-Kind shapes. The Maple Leaf is hand stamped and attached. The base of the mug are trimmed by hand. After their first firing , The Maple Leaf mugs are then highlighted with a colored under-glaze. The Maple Leaf color will match the mug color. All my pieces are hand dipped in 100% Lead free high fire glazes. All my pieces are microwave, oven, and dishwasher safe.
