Line blends are
used when you may want to explore
- changes involving
a single material in a recipe e.g. if in the Cone 10 Glaze recipe
we wanted to explore the effects resulting from changes to just
- the variations
in colour from the addition of a single colourant.
- the results
of blending two different recipes. e.g the B recipe in the blend
may be designed to have less Al2O3 an SiO2 than the A recipe such
that the Al:Si ratio is kept constant
We will use
the last case above as an example. We have already designed this
the Corner Recipes for the Line Blend
need to have three recipes for the corners of the triaxial
A - will be the original Cone 10 Glaze recipe
Corner B - will be the Cone 10 Glaze altered
to reduce Al2O3 and SiO2 levels maintaining the Al:Si ratio
recipes were prepared in the Recipe to Formula environment. After
making the reductions indicated above the recipes were converted
to total 100. Note that the recipe names include the letter which
indicates in which corner the recipe will be place.
All three recipes
were saved to the following location: C:/Prgram Files/Matrix/Blends/Cone
