But for now these glazes are very satisfactory to me and their visual quality seems long-lived. Just so smitten with your work. I want all of those. Look forward to seeing your work again someday. Hey Phil, we had a batch of American Shino that I was told needed to be remixed. I gave it a go anyways and I really liked the results. Rather than coming out so orange, it was mostly a creamy white with slight orange breaks on the edges, pinholes, and it crazed.

On some of the pieces, it carbon trapped quite nicely. Do you know what would have caused this so I can use it to my advantage again? Too thick, substituting ingredients? Hey Chris! I am glad you like American Shino! It sounds like you applied the glaze quite thick, which would give it that creamy white color. As for the carbon trapping, generally that is helped along with soda ash.

Thanks for sharing your recipes! My experience since I started throwing pottery a bit over a year ago has been mainly cone 6 stoneware, but I was recently offered the opportunity to help with an anagama firing and include some pieces.

I came across your American Shino recipe in my search for cone 10 glazes and mixed up a batch to try on a few porcelain pieces. Hello Jay, Thanks for saying hi! I am glad you happened upon the American Shino recipe! I hope the results are as favorable as they have been for me! I would love to see the results when they are finished, so please respond back if you have time!

My apologies for not responding back much sooner. They were all porcelain and I dipped it on relatively thick.Share from Insight-live. See Also: Zero3 Ulexite-based glaze, engobe and firing schedule. If you are doing low temperature earthen ware, especially for functional pottery, then start with a good transparent base clear recipe.

Read about all of these and choose. A good base clear for low temperature ceramics is vital for success. It can become the base of all of your coloured glazes. And a kiln firing situation where you can do lots of testing is important. After all, if you can do a firing in 3 hours, it is much more practical to do testing.

High Fire Glazes

At low fire, boron is the king of fluxes. And frits are the key sources not a single commercial glaze manufacturer uses Gerstley Borate to source boron, yet many potters still do. What is the perfect combination of Ferro frits to create a super clear glossy glaze for low fire?

There are an infinite number. But that number is drastically reduced when we eliminate those of too-high and too-low thermal-expansion-adjustable. And those that are not durable and resistant to leaching.

And those that are not compatible with stains we need. And those that do not heal blisters and pinholes well.

Raw glazing for once firing, cone 10 tips, thoughts - June 27 with Simon Leach

Potters coming to low fire from higher temperatures expect fired strength, that is just not there at cone But terra cotta bodies fired at cone are dramatically better. GK is intended for exactly this at cone 04 and lower it loses clarity and the surface is not as smooth.

G, on the other hand, melts well at lower temperatures. Good low fire glaze can be applied in a much thinner layer than at higher temperatures and yet still look full bodied. A thinner layer will also produce a more crystal-clear product.All Glossary.

Do not get addicted to the trafficking in online glaze recipes. Learn how they work. Understand them. Details We have included this page to warn you about recipes that you find online. Be careful about wasting your time. And money. Do not think you will find a magic solution to all your dreams! What you will more likely find is alot of frustration and a stock of useless materials. Better to have a few recipes you understand and can control than 50 renegades that put you through hell to use and keep consistent or just work sometimes.

Recipes are trafficked, often just taking space on pages. People pass them around without a thought. Or any knowledge of them.

Having no documentation. The actual recipe is only one part of the puzzle to create functional and aesthetic ware. Recipes have advantages and disadvantages. Specific visual effects often come glazes that are very difficult to use and teeter on the edge of all sorts of precipices e.

Procedures are often specific to recipes. Recipes often have mechanisms e. People fail to document these! But published recipes are often, very often, simply wrong. They are nonsensical, have wildly crazy chemistries, use dangerous or difficult materials, fire to leach-prone surfaces, craze badly on any body, cutlery mark or stain easily. Understanding glazes is better.By tanviMarch 22, in Clay and Glaze Chemistry.

I am looking for a pink glaze recipe that fires at cone and stays bright. So far everything ive seen on the market fades at that cone temperature. And the recipes I found online are not quite bright. I know using chrome tin makes a glaze pink. Anyone has a recipe to achieve the attached color at high fire?

Base has to have a high amount of calcium to develop the pink colour. Mason stains and Crimson and Alpine Rose both hold up at cone 6.

Unless you're firing in reduction? High fire seems to have different meanings each side of the pond. You can post now and register later.

When mixed together, the recipe's materials form a new type of material- a clay suitable for throwing, a beautiful, shiny glaze, or a colorful underglaze.

The recipe below is a classic recipe called "Leach ". Leach is often used as an example because its recipe is very simple and it works well:.

It's important to realize that this is the same recipe as listed abovejust multiplied by and specifying a unit of measurement. Potters often write down recipes in batch sizes that they work with to make mixing glazes easier. A batch size of 10,g like the one above is often used when making up a large bucket of glaze or clay. Because recipes list proportions of ingredients, no units of measurement are used.

To make this recipe, you can measure in ounces or grams, even kilograms or tons! For convenience ceramicists usually stick to the Metric System. Batches of recipes are measured in grams and kilograms. Small test batches are usually only or grams, while batches for daily studio use can be 10 or 20 kilograms. More information about mixing up batches: Mixing Test Recipes. Underneath each recipe listing is a Calculate Batch input box.

After entering a number into this box, Glazy will calculate the total amount for each ingredient. Recipes are often divided into two sections: the base recipe and additional ingredients. Imagine a recipe for pizza. The base recipe would include the ingredients for making the dough and sauce, while toppings like mushrooms and sausage would be listed as additional ingredients.

For glaze recipes, the base recipe is usually a plain glaze without any color. Additional ingredients like colorants and opacifiers can be added to change the look and character of the original base recipe. Notice that the name of this recipe has changed.
