What temperature is cone?
Cones should be calcined to about 850°F (455°C) in an air atmosphere. If a cone is soaked at a temperature near its equivalent temperature, it will continue to mature, form glass and bend.
What cone is bisque fire?
Generally, bisque firing is done between cone 08 and cone 04, no matter what the maturation temperature of the clay and of the glazes that will be used later. By cone 08, the ware is sintered and has become a ceramic material. At the same time, the clay body still is quite porous and absorbent enough for easy glazing.
How hot does a kiln have to be to fire clay?
1,800 F to 2,400 F.
In modern societies pottery and brick is fired in kilns to temperatures ranging from 1,800 F to 2,400 F.
Is cone 5 or 6 hotter?
That is not to be ignored! Cone 6 is about 400 degrees hotter than cone 06! As you can see from the pyrometric chart (above), the “0” serves as a negative sign. Therefore cone 05 is cooler than cone 04 whereas cone 5 is hotter than cone 4. For the most reliable results, it is best to match your clay with your glazes.

What temp is bisque firing?
The most common temperature to bisque fire pottery is cone 06 – 04. This equates to around 1830 – 1940F, (999-1060C). However, potters do bisque fire at other temperatures. The right temperature to bisque fire depends partially on the clay you are using.
Can you bisque to 06?
What Cone do you fire Terracotta?
Terra cotta bodies need to be bisque fired fairly low (e.g. cone 06) to have enough porosity to work well with dipping glazes.
Why did my clay melt in the kiln?
If the clay body is intended for low fire, but it was actually fired to cone 6, then the clay itself was overfired, thus melting in the kiln. Your kiln sitter may still be working properly.
What cone is low fire clay?
Low-Fire clay, also known as EARTHENWARE clay fires in the cone range of cone 06 to cone 1. Most commercial low fire glazes fire cone 06/05/04. Firing higher than this can cause serious warping of clay pieces, or even worse, complete melting of a project at high fire.
What cone is low fire glaze?
The term low-fire in pottery refers to firing processes that are done at a relatively low temperature, typically cone 04 to cone 06. The term also describes clay bodies and glazes that are suitable for low-fire firing.

What Temperature Should a Bisque Firing Go To? Generally, bisque firing is done between cone 08 and cone 04, no matter what the maturation temperature of the clay and of the glazes that will be used later.

What is cone 1 temperature in kiln firing?
Kiln firing at cone 01 temps is considered a “low-mid” firing range. Cone 01 temperature is typically where low-fire clays become durable or structural vessels. For instance, terracotta clay turns from red to brown and becomes nonporous at cone 1 temps. The cone 1 temperature range does not typically result in a glass or gloss-like finish.
What is the firing range of a firing cone?
The following cones (010 to 02) are in a “low” firing range. The temperature range is 1636° – 2138°. This range is most commonly used in bisque firing (one of the stages of clay) and firing some glazes. Kiln firing at cone 010 temps is considered a “low” firing range.
What are pyrometric cones used for?
A range of pyrometric cones are used since different ceramics bodies require different heat treatments. This resource includes a kiln firing chart in Fahrenheit and Celsius. This is a table describing cone temperatures in Fahrenheit. This is a table describing cone temperatures in Celsius.
