- CIMTUFF® 9107 is also used to produce low expansion ceramics, for example thermal shock resistant stoneware bodies.
- In these, it acts as a low expansion flux that reduces body expansion by converting available quartz mineral, mainly in kaolin, to silicates of magnesia.
- Cordierite bodies used in kiln furniture and flameware (and a host of other applications e.g. catalytic converters) employ a high percentage of Cimbar talc and extend this concept so that all free quartz is used up.
- CIMTUFF® 9107 is itself a refractory powder; yet in amounts of only 1-3% in stoneware or porcelain bodies it can drastically improve vitrification!
- Yet adding these same low percentages to some zero-porosity highly vitreous bodies does cause them to warp, blister or over fire.
- Cone 06-04 ceramic slips containing up to 60% talc can be fired to cone 6 without melting or even deforming (50:50 mixes can even go to cone 10).
- CIMTUFF® 9107 is a curious glaze material also.
- At middle temperature raw talc is refractory, its presence tends to create opaque and matte surfaces, yet if supplied in a frit it can create wonderfully transparent glossy glazes.
- At cone 10 it is a powerful flux but also can be used in combination with calcium carbonate to create very tactile magnesia matte glazes (the MgO forms magnesium silicate crystals on cooling to give both opacity and a matte silky surface).
- This being said, where transparency is needed it is generally best to source MgO from a frit (since talc loses its water of hydration quite late in the firing, after melt of most glazes has begun).
