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.
