Cone 08 Ceramics

Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials.

Cone 08 ceramics.

Stoneware glaze some decals fire to cone 10. The cones often used in sets of three are positioned in a kiln with the wares to be fired and provide a visual indication of when the wares have reached a required state of maturity a combination of time and temperature. Generally speaking the temperatures in the 108 f hour column are used when discussing ceramics porcelain and china. 1798 1828 1855 1776 1816 1828 1823.

Cone art glass fusing kilns. Cone temperature conversion chart. As discussed above the equivalent cone temperature depends upon how fast one gets to it. 1692 1728 1753 1695 1735 1755 1728 1749 1733 1751 1801 07.

In general the following cones are used in the pottery studio. We recommend always buying a kiln that is specified for a higher temperature than you plan to fire. Bisque fire cone 08 05 low fire cone 06 04 mid range cone 4 7 and high fire cone 8 10. 1764 1789 1809 1747 1780 1800 1783 1805 1778 1796 1846 06.

Because cones are made from carefully formulated ceramic compositions they bend reliably at specific temperature ranges. Thus pyrometric cones give a temperature equivalent. Please note that the cone chart gives 3 different temperatures for each cone number. For example cone 06 indicates a temperature range of approximately 1800 1850f.

Each cone type is assigned a number for example cone 06 and this number denotes a specific and fairly narrow temperature range. Cones are used in every firing. Ware and glaze types. If you plan to fire mostly to cone 6 or 8 a regular cone 10 kiln.
