The Art of Firing
Z-Ring Advantages
- Eliminates cold zones on firing tray
- Completely even heat across the tray surface
- Eliminates dull glaze finishes (fire scale) caused by uneven temperature in firing zone
- Optimizes depth of shade vitality of all layered ceramic applications
- Adjustable ring accommodates larger cases
