Welcome to GlazeSimulator.com

GlazeSimulator.com has been designed to unite the strengths of surface and color observation with the analysis of glaze structure using glaze calculation software. GlazeSimulator.com offers three ways to work: Analyzing, Creating and Adjusting glaze recipes. GlazeSimulator.com offers a very powerful Analysis dashboard as well as Wizards to promote an interactive approach to Creating and Adjusting your glaze recipes. Each approach has a separate screen and Help document. There are many components that allow you to customize your experience, explore relationships between materials on either a global or regional basis and alter and experiment with your recipes. Please take some time and read through the Analysis Page overview below.

While we hope you find GlazeSimulator.com a powerful glaze development tool it is important to understand the limits of glaze calculation software. This system provides approximate information based solely on generalized and theoretical data. It is beyond the capability of glaze calculation software to incorporate variables unique to specific studio conditions. For example a mid fire glaze heated over a long firing cycle with an extensive soaking period could easily have similar oxide characteristics as a high fired glaze. A glaze with a moderate expansion value may still craze on certain clay bodies. There are many exceptions to the rule in glaze development and no substitute for doing your own research and development. We hope GlazeSimulator.com offers you a great place to explore glaze development.

Analysis Screen


Main Analysis Page - Tabs

Help with Making Pottery Glaze Recipes

These Tabs are found on the Analysis Screen and give you access to the Create and Adjustment Wizard screens.

Main Analysis Page - Left Section

Glaze Calculation for the Studio Potter The left column of the GlazeSimulator Analysis page groups together access to Materials. You can choose to limit the listings to your region in the world or leave the default Global setting. The Select Material Category box offers a list of material categories. Click on this control and select a category. The Materials box below will fill with all the available materials from that category. When you find the material you want to add to your glaze recipe click on the name and it will appear in the first available empty field of your recipe.

GlazeSimulator.com provides local data storage on newer versions of most browsers. The first Saving Pottery Glaze Recipes for the Studio Potter icon Saves your recipe. The second icon beside the Materials Category selection opens a screen for building your own My_Materials list. You can use this list for quick reference to the materials you use most. The firstDeleting Pottery Glaze Recipes for the Studio Potter icon will Delete the current loaded Recipe. The second Delete icon will open a window making it possible to Delete all your recipes.

If you save sensitive data in this browser, on this computer, make sure only trusted users have access. If you do not want to leave your recipes on this browser, on this computer, click on the delete (red X) beside the Recipe List when you are finished your session.

If you wish to skip scrolling through lists of materials you can use the Find Material search box. Enter the name or part of the name you are looking for and click the Find Material Button button. If any materials matching all or part of your search are found they will be displayed and available for selection.

In the event you want to select a material based on its constituent oxides or search for similar materials click on the Materials Query link.

The following controls are used to select Color definitions to be applied to your recipe. The Firing Atmosphere has three to choose from. These settings are important when selecting and predicting color properties for your glaze recipe. Oxidation is usually associated with electric kiln firing. Reduction is usually associated with gas firing and OxRed refers to colors that will work in both Oxidation and Reduction firings.

If you want GlazeSimulator to help you formulate a specific color follow these steps:

Select a general color from the Choose a Color Category. This control will allow you to choose a general color from a list. Once you have chosen a general color, the screen will refresh and a Specific Color list will appear directly below this control. You can now choose the color description you want from this list.

Once you have choosen a Specific Color the Show Color Definition and the Change Recipe Color buttons will appear. If necessary use the Show Color Definition to display what the selected Color Definition. This will tell you what colourants will be added to your recipe and any Base Oxide restrictions you should be aware of before changing your recipe. Once you are satisfied with the Color Definition click the Change Recipe Color button and GlazeSimulator will modify your recipe to include the necessary colorants. Colorants will be added to your glaze recipe but the base materials and amounts will not be altered.

Note: when you choose a new color for your glaze recipe all existing colorants in your recipe will be removed before the new colorants are added. When your submitted Color Definition does not appear in the Possible Colors list this indicates that either the Atmosphere or Melt properties of your recipe and this Color Definition are not similar.

Main Analysis Page - Middle Section

Glaze Calculation Software for Making Pottery Glazes

There are three main controls in this section of the Analysis Page. You can display a graphical analysis of your glaze recipe for either Percent Analysis or Melt Analysis. The Percent Analysis shows a color coded graph of your glaze recipe divided into three categories of oxides: Glassformers (blue), Alumina (light orange), and Fluxes (green). The Melt Analysis graph shows the probability of success across several cone ranges. The cone range with the highest probability is the cone range where your glaze will most likely melt. In cases where the Melt Analysis cannot predict a cone range a single bar extending across the graph will be shown.

Under the left side of the graph(s) is the Analyze Button and below that a list of text boxes. Once you have selected your recipe materials and entered positive numbers for each material, clicking on the Analyze Button will refresh the Main Analysis Page with updated information about your glaze recipe. The red (crossed lines) icons to the left of the material text boxes provide a way to clear a field if you decide not to use a specific material. Once a material text box has been cleared it will be automatically filled the next time you select another material or process the page again, by clicking on the Analyze Button. The graph icon to the right of the amount boxes displays a graph of its corresponding material when clicked.

Directly under the graph is a general information window. The links under Display, Properties and Possible Colors will display information in this window. Please refer to the Main Analysis Page - Right Section (below) for more details.

Main Analysis Page - Right Section

Help with Making Pottery Glaze Recipes This section of the Main Analysis Page consists of rollovers that display all the information made available by GlazeSimulator about your glaze recipe.

This section displays glaze recipe information in three categories. The first category is Analysis. Under Analysis you can select Percent, Seger or Flux Unity graphs. When you rollover any of these selections the a graph will be displayed. An brief summary of each is also displayed in the information section beside your recipe. The second category is called Recipe Properties. The properties you can display are as follows: Expansion (Coefficient of Expansion), Ratio, Cone Range and Adjustment Notes. Each of these properties are summarized with a description in the information section when selected. Cone Range provides a quick display of the predicted Melting range. Adjustment Notes displays the change in the above properties after an adjustment has been made to your glaze recipe.

The last section is called Color Range and will list one or more Color Definitions, if applicable. Each color definition represents one possible color based on the selection of firing atmosphere and the colorant(s) included in your recipe. When you move your mouse over each definition you will see information about each color in the information section. Base oxides that are Recommended, Necessary or that should be Excluded in the recipe in order to achieve this color will also be listed. The Color Range list shows all the colors possible based on the Firing Atmosphere and Colorants included in your recipe. In some cases a sub list --Out of Range-- will display more Color Definitions. These colors fall within some but not all current glaze conditions.
