Botz Pro Combos on the G&S930 stoneware by Kristina Büchner

Botz Pro tumblers by Kristina Büchner

Botz Pro tumblers by Kristina Büchner highlight the rich surface possibilities of Goerg and Schneider 930 stoneware, combining earthy material with fluid, expressive glaze work. These handmade tumblers feature layered applications of Botz Pro glazes that melt and interact during firing, creating soft transitions between purple, caramel, and deep blue tones. The natural warmth of the stoneware body subtly contrasts with the glossy glaze movement, enhancing depth and visual texture.

Crafted by Kristina Büchner, each tumbler is finished with attention to both form and glaze behavior, then fired to 1200°C with a controlled hold to develop the signature flowing effects. The combination of Botz Pro Amethyst, Carnelian Yellow, and Malachite produces dynamic overlaps and organic variation, ensuring that every piece is unique. These tumblers demonstrate how stoneware can be elevated through thoughtful glaze layering into functional yet artistic ceramic work.
