Cone 10 Reduction Glaze
Unique Every Time
No two pieces are identical in pottery, especially when working with gas kilns and various glazes. Even if two pots are glazed and fired the same way, the fluctuating conditions inside an unregulated gas kiln—such as temperature, atmosphere, time of reduction, proximity to inlet or other ceramics—make it impossible to replicate results. These factors lead to unique variations in color, texture, and finish. Rather than expecting perfect control, it is important to embrace the individuality and character given to every fired piece.
Fired Fragments
At this scale, glaze really turns into its own little world — rough edges, shiny pools, and mineral spots all hanging in a kind of balance. Every piece is fired to Cone 10, and that means heat, oxygen, and glaze all mix together in ways that never happen exactly the same twice. Sometimes you get iron spots, other times oxidation marks, or just random traces left behind by how the kiln heated each spot. When you look this close with macro photography, you see things most people miss — tiny cracks, bubbles, subtle color shifts. Even the smallest change in how thick the glaze is or where the pot sits in the kiln can make a big difference in the final surface. These shots aren’t just pictures — they’re a way to really slow down and study the unpredictable effects of firing, the little details that make each piece truly unique. Glossary of Terms: Crazing: Fine cracks in the glaze surface caused by differences in shrinkage between the glaze and clay body during cooling. Oxidation: A firing atmosphere where oxygen is plentiful, affecting the glaze colors and surface effects. Iron Spots: Small dark or rusty-colored spots caused by iron oxide in the glaze or clay reacting during firing. Cone 10: A high-temperature firing range (about 2345°F or 1285°C) used for stoneware and porcelain. Kiln Hotspot: Areas inside the kiln that get hotter than others, causing variation in glaze effects. Macro Photography: Extreme close-up photography used to capture very fine details not visible to the naked eye.
