Twilight Fireflies Mug An eye-catching mug that embodies the great outdoors and summer memories! Adorned with impressions of fireflies among the pines and a double glaze of evening blue and field green, this slab-built mug is a little work of art for your coffee or tea! Artist-made in Wisconsin, the mug features a comfy, sculpted handle, sturdy rectangular bottom, and a 12-ounce capacity. The solid, high-fired stoneware is plastic-free, lead-free, microwave safe and dishwasher safe. What does slab-built mean? Unlike mugs that are formed on a pottery wheel, this mug is built from a flat slab of clay. Each is uniquely folded and shaped in a multi-step process that also requires multiple days of kneading, glazing, and firing.
