Data is Stored for each Raw Material in a Database

Matrix provides for the following data to be stored for each raw material record in it's databases:

  • Name of Material This must be a unique name (no longer than 30 characters) which identifies the material.

  • Oxide % Analysis Manufacturers usually provide raw material data in this form.

  • Seger Formula Sometimes the data you enter for a new raw material file may be in this form.

  • Matrix Calculation Formula When entering a new raw material you may decide that some of the oxide values are too small to be significant and may choose to have Matrix ignore these trace oxide values.

  • Molecular Weight If you originally entered Oxide % Analysis data when placing the material into a raw material database then the Molecular weight of that material will be calculated automatically by Matrix.
    If instead you originally entered a Seger formula then you will be required to supply it's Molecular Weight.

  • Loss on Ignition (L.O.I.) This refers to that part of a raw material which burns out or is lost during the firing. This value is usually supplied by the manufacturer or supplier with the material's Oxide % Analysis and is only entered when this type of data is entered for the material.

  • Cost per Kilo If the current cost to you of the raw material is available then you may enter it when you place the raw material into the database. If all of the material costs are available when the recipe is entered or displayed in Matrix then the cost of that recipe can be calculated by Matrix. More...

  • First Fill Oxide (Fill1) When material databases lists are displayed for the purpose of creating a recipe from a formula Matrix looks for any material with the target oxide represented. An asterisk is placed by some of those materials to indicate that they are primary sources of the oxide. Matrix uses the Fill1 record to locate primary source materials. When entering a material you must indicate which oxide this material would primarily be used to place in the glaze.

  • Second Fill Oxide (Fill2) A raw material may sometimes be a primary source for more than one oxide. e.g. Dolomite could be a primary source of both MgO and CaO. This record gives you the opportunity to indicate a second primary source oxide.

  • Abbreviation This should be a shortened version of the name (no longer than 6 characters).

  • Source of Data The source of the data originally entered into the database together with the date of entry is important information particularly when Matrix is used in a group situation such as a school.

  • Category This description of a raw material enables matrix to sort and filter a long list of raw materials when the user needs to quickly locate a particular material.The categories used are Feldspars, Fritts, Clays & Others.

  • Input Data Type When the material is first entered Matrix needs to know what kind of data is being entered i.e. % Analysis or Seger Formula.

  • Date of entry (or when last changed)

  • Comment limited to 256 characters

Maximum Size of Material Databases

A raw material database created by Matrix will hold a maximum of 100 materials. You may create as many databases for materials as you wish.
