Solar Rainbow is a highly fluid, dark gloss glaze with iridescent rainbow crystals. Breaks translucent.

Supernova is a highly fluid creamy white translucent glaze with a crystalline surface like frost on a window. The gloss glaze surface is opalescent and breaks slightly more cream than white.

Solar Flare is a highly fluid light brown glaze with an iridescent crystalline surface. Opaque and glossy with a slight texture on the crystals.

Dark Star is a fluid, dark matte glaze with iridescent crystals like a beetle shell. Breaks translucent.

Large Pyrometric Cones allow users a practical method to monitor the heat work (the effect of temperature and time at temperature) inside their kiln.

Orton’s patented Self-Supporting Cones are the most accurate and easy to use witness cones available. Since the correct height and angle are built into the cone, reproducible firings can be achieved time after time.

Small Cones are commonly used in the Kiln-Sitter—they are not used as witness cones. The tapered shape allows some flexibility to adjust shut-off by placing the thinner or thicker portion of the cone under the sensing rod.
