This is not a chemistry project, it is about an organized program of physical testing and record keeping to develop body recipes for various common cones.
Project Name Making Our Own Pyrometric Cones Project Codenumber UnAssigned Notes This page is about developing the recipes for making cones. First, I want to develop a mix that bends correctly at cone 6. Then develop rules on how much to increase and decrease the frit to adjust for bending at cones 7-10 and 2-5. Or, it might be better to develop a recipe that works for cone 10 and then make the intermediate cones by mixes of the 6 and 10. |
Pyrometric cone pressing body #2
Total:113.00
Notes *This is version 2 of the series, it doubles the initial frit percentage and adds VeeGum as a plasticizer (and removes CMC gum). It is possible to press this into the 3D printed molds when it is very stiff. However drying is an issue, the top thinner section is drying first and sometimes cracking away partway down. Pictures L4532A at cone 7 An orton cone on the left, this trial on the right. This is almost bending enough at cone 7.

Cone pressing body #3
Total:103.50
Notes *The recipe has been retotalled to 100 (plus the Veegum) and the frit has been increased at the expense of silica. This should be plenty to bend it too much at cone 6. Then a blend of this and L4532A will produce the desired recipe.

Cone pressing body #5
Total:107.25
Notes *In comparing this with L4532B, which bent correctly at cone 5, this has 3.5% less frit, and is bending correctly (like the Orton) at cone 6.
