Current Community Glaze Recipes Here is the list of glazes currently available in the Community Glaze Recipes section.
Potters are given the option to include their glaze recipes in the Community Glaze Recipes section when they first enter their recipe and whenever they update a recipe. When a ceramic glaze recipe is included in the Community Glaze Recipes section, only the glaze name and description are shown. The actual recipe is not revealed. Other potters are allowed to purchase the glaze without knowing the actual recipe.
Every time a glaze recipe sells in the Community Glaze Recipes section, the potter that placed the glaze recipe receives 10% of the price cash back.
The Community section is a great way for ceramic artists to share their glaze recipes. The list currently contains many high-fire glaze recipes, low-fire glaze recipes, raku glaze recipes and mid-range Cone 6 glaze recipes. New recipes are added every day!

Current High-Fire Ceramic Glaze Recipes |
What is a High-Fire Glaze?High-fire ceramic glaze recipes are typically fired in the range of Cone 8 to Cone 11 (2280 degrees Fahrenheit to 2361 degrees Fahrenheit). High-fire glaze recipes are sometimes referred to as Cone 10 glaze recipes or feldspatic glaze recipes. High-fire glazes are sometimes called feldspatic glaze recipes because feldspar is usually the primary flux or melting agent. High-fire glazes in general are very hard and durable and have softer muted colors.
For the most part, high-fire ceramic glaze recipes are created to be used in a pottery studio setting. Historically, the pottery studio has contained a high-fire gas kiln. These types of gas kilns have dampers and blowers that can control the amount of oxygen entering the kiln. At certain points in the firing, the oxygen can be limited, creating an oxygen starved or reduction atmosphere. High-fire glaze recipes are often fired in this oxygen reduced atmosphere. |

Current Low-Fire Ceramic Glaze Recipes |
What is a Low-Fire Glaze?Low fire glazes are usually fired in the range of Cone 06 to Cone 04 (1828 degrees Fahrenheit to 1945 degrees Fahrenheit). Because of their low firing temperature, low-fire glazes are able to hold much brighter colors than high-fire glazes. They also have a wide range of finishes including glossy, matte and specialty surfaces like crackle and crystal. The low firing temperature of low-fire glazes has a down side. Low-fire glazes are much less durable that higher fired glazes and it is difficult to have a low-fire glaze that is safe for food.
Low-fire glaze recipes are usually developed for use in electric kilns. Electric kilns are much easier to control that gas kilns and they provide a much more even source of heat. This allows potters to control low-fire glazes much better than high-fire glazes.
Electric kilns normally do not have dampers to control the oxygen levels inside. There is usually a constant stream of oxygen being pulled into the kiln. As a result, when pieces are fired in electric kilns they are often referenced as being fired in an oxidized atmosphere. |

Current Mid-Range Cone 6 Ceramic Glaze Recipes |
What is a Mid-Range Cone 6 Glaze?A mid-range glaze is usually fired in a range from Cone 4 to Cone 7 (2124 degrees Fahrenheit to 2262 degrees Fahrenheit). A Cone 6 glaze is a mid-range glaze that should be fired to Cone 6. Mid-range glaze are normally created to be fired in an electric kiln. Mid-range glazes often mimic effects achieved in high-fire gas kilns. Although Cone 6 glazes are fired at temperatures lower than high-fire glazes, the melting points are still considered to be high. As a result, the glazes are much more durable than low-fire glazes. Often, high-fire glazes can be adjusted to have their melting points lowered to mid-range temperatures. As energy costs rise, mid-range Cone 6 glazes become more popular. It is very expensive to push a kiln from Cone 6 to Cone 10. So, if the desired effects can be achieved at Cone 6, costs can be cut for the potter. |

Current Raku Glaze Recipes |
What is a Raku Glaze?A raku glaze is a glaze that is fired in the raku process (but sometimes potters fire raku glazes in traditional kilns and sometimes potters fire traditional glazes in raku kilns). The normal raku glaze has a melting point between cone 07 and cone 06 (about 1800 degrees Fahrenheit).
The raku firing process usually takes place outdoors in a special raku kiln. The piece is fired up to temperature in the raku kiln. The raku pottery piece is then removed from the kiln while the glaze is flowing (red hot) with raku tongs. The raku pottery piece is then immediately placed inside a metal can full of combustible materials (usually paper, leaves or sawdust). The metal can is sealed with a lid. The pot is nearly 1800 degrees Fahrenheit, so the heat emitted from the raku pottery piece causes the combustible materials to catch on fire. Because the can is sealed, oxygen is permitted from feeding the fire. As a result, a reduction atmosphere is created and oxygen is drawn out of the raku piece. This reduction in oxygen gives some raku glazes a metallic luster and other raku glazes dark crackled lines.
After the raku pottery piece has been reduced for 10 to 15 minutes, it is removed and submerged in a can of water. This stops the reduction and freezes the patterns in the raku glazes.
Because the raku process can crack the glaze and clay body and because the firing temperatures are so low, raku glazes are not food safe. |

Current Salt Glaze Recipes |
What is a Salt Glaze?A salt-glaze is a glaze that is meant to be fired at high temperatures normally between cone 9 to cone 11 (2300 degrees Fahrenheit to 2361 degrees Fahrenheit). During the firing, salt (sodium chloride) is added to the kiln chamber through peepholes. A salt-glaze does not get its name by containing salt in the actual salt-glaze recipes, but because it is a glaze that is meant to be fired in a salt kiln, with salt added during the firing. Often, pottery that is salt fired is glazed with salt-glazes or salt-slips that increase the effect of the salt that is added during the firing.
A form of hydrochloric acid is given off during a salt firing, so protective respirators are required. Salt fumes give the pottery a blush of color and a glassy finish. Normal salt-glazes have a glossy orange-peel finish.
Sodium acts as a flux or melting agent, creating a glass all by itself as it combines with the silica in the clay body. As a result, pottery being fired in a salt kiln must be set on wads of resistant clay or other materials that are resistant to high temperatures. Without the wadding, salt fired pots would be fused to the kiln shelves.
Because salt-glazed ceramics are fired at high-fire temperatures, they are very durable and are normally safe for food. |

Current Wood-Fire Glaze Recipes |
What is a Wood-Fire Glaze?A wood-fire glaze is a glaze that is meant to be fired in a wood kiln or anagama. Wood-fire glazes are normally fired to very high temperatures from cone 9 to cone 11 and sometimes higher (2300 degrees Fahrenheit to 2361 degrees Fahrenheit).
A wood-fire kiln is fueled by wood. So, a pottery firing an anagama has to continually supply or stoke the kiln with wood during the entire firing. The firing can often take days to finish. Throughout the firing, ash from the wood builds up on the pots and acts as a flux or melting agent to encourage glass to form. Often, wood-fired pottery is fired unglazed. When wood-fire glazes or wood-fire slips are applied on pottery, is helps enhance the finish.
It is much harder for a potter to control the direction and force of heat temperature in a wood-fire kiln. As a result, the finish of wood-fired pottery contains many variations in color and texture. |

Current Ash Glaze Recipes |
What is an Ash Glaze?An ash-glaze is a high temperature glaze that contains wood or volcanic ash. Ash-glazes are normally high-fired between cone 9 and cone 11 (2300 degrees Fahrenheit to 2361 degrees Fahrenheit). Ash acts as a flux or melting agent that causes glaze to form. Normal ash glazes have ash runs or a streaky texture on the surface of the pot. |

Current Crystalline Glaze Recipes |
What is a Crystalline Glaze?A Crystallin Glaze is a glaze that contains crystal shapes in the finish. Crytalline Glazes are normally fired in electric kilns where the current temperature and rates of termperature climb can be controlled by the potter. For crystals to form in the glaze, particals in the crytalline glaze must be free to move around and join up together. As a result, the glaze must be very molten. Because of this, the glazes flow very easily and run off of crystalline glazed pottery. Often, crystalline glazed pottery is fired with a dish underneath to catch the excess flow of glaze. |

Current Kazegama Flashing Slip Recipes |
What is a Kazegama Flashing Slip?Kazegama flashing slips and glazes are for use in the Kazegama kiln developed by Steve Davis. The Kazegama achieves wood-fire results in about 6 hours compared to the several days that are required to do a wood-firing in a traditional anagama.
After being fired to maturity with propane, screened wood ash is introduced into the Kazegama through blower burners. The ash is distributed on the ware in the kiln and subtle flashings, heavy ash flows, carbon trapping, and dry, crusty, melon surfaces are achieved.
