Nate Winter Studios | Handmade Pottery on Instagram: "Laurie just finished her first Raku workshop with me, and look at this wild iridescence! This dish was a standout with flame-like metallic colors dancing across the surface. That’s the magic of copper carbonate in reduction. When starved of oxygen and cooled quickly, copper shifts into those vibrant, oil-slick tones. Drop some love in the comments and let Laurie know how stunning this piece turned out! #rakufiring #pottersofinstagram #ceramic
