Excellent Folky-Modernist Ceramic Trivet

The colorful glazing on the sides of this handmade ceramic trivet is really cool, but makes it a bit challenging to photograph as the color casts a glow under light--trust that it is sharper and crisper looking in person, while yet also feeling very homemade; modernist and folky at the same time, and also reminding one a bit of a kindergarten cut paper snowflake. Hand-drawn sgraffito for the white lines with glossy gray-blue and black glaze and a coiled ring on the underside to nicely ground it. Super, and feels as much deserving to be hung on the wall as set on the table.

7 1/2" x 5 3/16" x 1 1/16" and in very good vintage condition, late 20th/early 21st c I believe.
