Creating Your Own Limits Data
Go to contents

If you are involved in researching glazes or a particular type, firing range, quality etc you may wish to try and establish a set of limits data which encompasses the glaze sets you are researching.

Matrix provides a window in which the formula for all recipes in a recipe database can be plotted. Fig.1

To open the Recipe Database Limits Graph Window click the Recipe Database Limits Graph item on the View menu.

Fig 1 The Recipe Database Limits Graph window

In Fig.1 I have opened the window and loaded a recipe database called Cone 6 Test Set.rdb This is a randomly selected set of recipes gathered simple for the purposes of this example.

The graph is set for the temperature C.6 and the limits data used is the Matrix.lim data.

Establishing a New Set of Limits Data for these C.6 Recipes

In Fig.1 the values in the text boxes on the right represent the upper and lower values for each oxide in the set of Cone 6 Test Set.rdb recipes. The bars on the graph represent the upper and lower limits for C.6 in the Matrix.lim file.

If you click the Apply Database Range button the bars will change for each oxide to represent the loaded recipe database.

Fig 2 The Recipe Database Limits Graph window after Applying the Database Range

You can return to the Matrix.lim limits by clicking the Restore Default Limits button.

After Applying the Database Range you can edit the values to exclude non-typical recipes in the set.

Saving the Generated Limits Data for Cone 6 Test Set

When you have adjusted the values to your liking you may save the data as a unique limits file for future reference. This file may be used in Matrix when any Limits Graph window is open.

To save the data:

  • click the Save As button. The Windows File Selector in the open directly in the Limits folder.
  • type in a new name for the limits data you have entered and click the Save button.

When you are working in Matrix and wish to compare the formula for a displayed recipe with the limits you have just entered you can use the Load New Limits File item on the Action menu for whatever graph you are using. This menu item opens a file selector window and the name for the new limits data you have entered will appear in the list. More ...
