These came from Carol at: www.carolbroadleypottery.etsy.com
Carol explains her process: "I always use maple leaves because they have such a pretty shape with all the points and great veins. I press the actual maple leaf into the clay, fire it with the leaves still on the clay (it just burns away). Then I color it with an oxide wash over the fired leaf, and fire it again to make the color permanent."
Stop by her shop and have a look at many other wonderful items that Carol makes! She's such a great talent and a great person to boot!
