Frog art tile was sculpted by Rick. Crafted from porcelain and Rick's specially formulated glaze. Using Rick's time tested recipes, we make small batches of glaze. Working small like we do, allows for variations in the glazes, creating one of a kind pieces. All of our tiles are designed and fabricated in our Michigan studio. The tile measures 2.75 x 2.75" (aka a 3x3" 'nominal' size) with raised relief of .5" or less. There is a notch on back for hanging. We recommend using a simple drywall screw. Can be used for installations in bathrooms and showers. If used outdoors in freezing temperatures, just make sure to keep it vertical. How’s it made? Sculpt the original design, make plaster mold, press in clay, wait to dry, fire in kiln, glaze, fire again to about 2230 degrees. Cool. Ship to your doorstep. Yay!
