Matrix will plot a glaze or a number of glazes on it's % Mol. Parts Triaxial graph.

To display this graph select the % Analysis Triaxial Graph item on the View Menu.

  Fig.1 % Molecular Parts Triaxial Graph - Full Mode

The graph (Fig.1) opens by default in its full size. This is indicated by the symbol filled with red.

The graph can be reduced to show the top half of the graph by clicking the button.

Fig.2 % Molecular Parts Triaxial Graph - Half Mode

In half graph mode the symbol changes to and the scale on the graph changes to

  • 0 - 50 for Basic and Amphoteric oxides and
  • 50 - 100 for Acidic oxides.

Plotting Recipes on the Triaxial Graph
An individual recipe may be loaded from disk by clicking the button and selecting a glaze from the File dialog box. Matrix calculates the % analysis values for the recipe's formula and plots the recipe's position on the graph. See Fig.2

A glaze may also be sourced from a recipe database by clicking on the button.

If a recipe is displayed in either the Recipe to Formula or the Formula to Recipe environments then that glaze will automaticially be imported into the % Mol. Parts Triaxial Graph when the graph window is opened.

Plotting a Group of Recipes on the Triaxial Graph

Matrix will display all of the recipes in a recipe database. This facility is very useful for exploring patterns in glazes which have common qualities and can lead to the ability to predetermine to some extent a particular outcome for an untested glaze.

To display a recipe database on the triaxial graph click the Load Database button and select the database you wish to display from the file selector dialog.

The glazes which appear on the graph will be listed in the Selected Glaze combo box which is only visible when the graph is in Load Database mode.

If you have the triaxial graph in half-graph mode then some of the glazes in the database may not appear on the graph. If the flux, amphoteric or acid values for a recipe in the database lies outside of the graph parameters then a text box will appear listing the name of the glaze which has not appeared.

Switching to full graph mode will make all of the glazes in the database visible.

Identifying a Glaze on the Triaxial Graph

When you have displayed a database of glazes on the graph you may identify an individual glaze by:

  • click on its yellow rectangle.
  • selecting the name of the glaze in the Selected Glaze combo box.

The rectangle on the graph representing the selected glaze will turn green and the name of the glaze clicked will appear in the Selected Glaze combo box. Its 5 molecular parts values will appear to the left of the graph.

Including Colourants in the Analysis

In its default setting the % Analasys Triaxial Graph will not include colourants in its analysis of the displayed glazes.

If you wish to include colourants in the analysis then click the Include Colourants check box.

If the atmosphere setting is on reduction then any iron oxide in the glaze will be included in the flux group.
With an atmosphere setting on oxidation iron oxide will be treated as an amphoteric.

Getting More Information About the Selected Glaze

If the glaze selected on the graph was loaded from disk (i.e. an individual file or from a recipe database) then the full glaze recipe, Seger formula etc may be viewed by clicking the Display Glaze button.

This opens the Recipe Search window which can be expanded to show all available information on the glaze.

Clearing Data from the Graph

To clear all data and displays from the triaxial graph click the Clear Graph button.

When you exit from the graph or close the graph window all data will be cleared.
