This melt fluidity tester compares two different tin oxides in a cone 6 transparent glaze (G2926B). Opacifiers affect not just opacity in glazes, but also liquid properties of the melt. The length, surface character, opacity and color of these flows provide an excellent indication of how similar the two materials are. This is the GLFL test.

Zircopax
Zirconium silicate, its principle use in ceramics is as an opacifier in glazes. It is an expensive material, but less so than tin oxide. |

Materials |
Tin Oxide
Its principle use in ceramics is as an opacifier in glazes. It is very expensive. |
Glossary |
Material Substitution
Material substitutions in ceramic glaze and body recipes must consider their chemistry, mineralogy and physical properties |
Glossary |
Melt Fluidity
Ceramic glazes melt and flow according to their chemistry, particle size and mineralogy. Observing and measuring the nature and amount of flow is important in understanding them. |

A Low Cost Tester of Glaze Melt Fluidity
Use this novel device to compare the melt fluidity of glazes and materials. Simple physical observations of the results provide a better understanding of the fired properties of your glaze (and problems you did not see before). |
