From the artist:
The key bowl has sky blue underglaze and green meadow on the inside, with arctic splash detail all over. I used screenprinting for the keys, a stencil for the letters, and an etching technique for the butterflies. The words say "yarn" in French. I love vintage keys so I was inspired to cover a bowl with them.
Non-toxic and food safe glazes are used on each bowl. It takes three layers of glaze for each color (more when I use underglaze too) and three layers of the clear glaze on top of those. The top glaze is what makes them smooth, food safe, and shiny.
