Jul 21, 2006· In ceramics, the addition of a flux lowers the melting point of the body or glaze. In particular they affect the melting point of silica (SiO 2), which melts to form a glassy phase during firing/sintering which bonds the ceramic body or forms the basis of a glaze.The addition of a flux also promotes fusion or vitrification (formation of a glassy phase) at lower temperatures than would ...

_____ Notes on Zinc Oxide _____ ZINC OXIDE (metal) Oxide Formula: ZnO Molecular Weight: 81.4 * Melting Range: With the relatively high melting point of 1800 C.,zinc is not an active flux at lower temperatures and is seldom used to encourage melting below cone 01. Zinc is not used as an active flux, but in smaller quantities it can be used as a ...
Potassium feldspar is commonly used as a flux in glassmaking and ceramics. Flux is a material that's added to a solid to lower the solid's melting point. The flux is a vital component of most glass and ceramic production because it helps control the viscosity of the glass and helps create a glassy phase in ceramics at low temperatures.
Dec 22, 2009· The presence of potash feldspar in a glaze or clay body has a more refractory effect on the ceramic surface compared to equivalent amounts of soda feldspar. Although potash feldspar actually begins its melt at a lower temperature than soda feldspar, once the melt begins, the formation of leucite crystals causes a slower and more viscous flow.
Because of its extremely low melting point and High Alumina Content, Nepheline Syenite is used as a Glass Phase Promoter, a Ceramic Flux and also as a functional filler in Paint, Plastics etc. Like Feldspar, Nepheline Syenite is used as a Flux in Tile, Sanitary Ware, .

Not really sure why you want to experiment with anything if you are that new, but feldspar is a flux used to lower the melting temperature of clay/glazes. So, depending on how much you mixed into the clay you may over fire them.
Fluxes lower the melting point of the glass formers in glazes, clay bodies, and other ceramic materials. ... content, which acts as the flux in the glaze, is caustic, so some people wash the ashes before use. Washed ash does not flux as well as unwashed ash, and will require more ash content in the glaze. ... A high soda feldspar that included ...

In ceramics, the alkalis in feldspar (calcium oxide, potassium oxide, and sodium oxide) act as a flux, lowering the melting temperature of a mixture. Fluxes melt at an early stage in the firing process, forming a glassy matrix that bonds the other components of the system together. In the US, about 66% of feldspar is consumed in glassmaking ...
