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.

Used to lower the melting point of the glaze. Minspar 250 Feldspar. Flux, Soda Feldspar, lowers the fusion point of bodies or glazes slightly. Frit 3134. frit that has been used for many years as a general purpose melter across all temperatures, frits are processed to make soluble materials insoluble.
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, .
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 ...
A density controlling material. Lowers melting point of ceramic material, Acts like another ingredient to fuse the body together at a given temperature, the more flux the lower it will be. Example Feldspar, nepheline syenite, kspar, Talc
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 addition of a flux also promotes fusion or vitrification (formation of a glassy phase) at lower temperatures than would ...
Since low fire glazes require more melting, they generally contain a higher percentage of FLUXES relative to SILICA than do the high fire glazes used on stoneware and porcelain. Simply stated, the more FLUX added to a glaze, the lower the melting point will be.
Kona F4 feldspar is a sodium based 1st choice main flux for glazes. Soda spars are very similar to postash feldspars except: § Have a slightly lower melting point. § May produce smaller, finer craze lines. § Have a slightly higher expansion and contraction rate. § .

_____ Notes on Zinc Oxide _____ ZINC OXIDE (metal) Oxide Formula: ZnO Molecular Weight: * 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 ...
Nepheline Syenite A very white feldspar having an unusually high proportion of sodium and potassium in relation to silica. Its lower melting point makes it useful as a body and glaze flux where a lower maturing temperature and purity are required. Materials, 1930 RAW MATERIALS .
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.
Fluxes are substances, usually oxides, used in glasses, glazes and ceramic bodies to lower the high melting point of the main glass forming constituents, usually silica and alumina. A ceramic flux functions by promoting partial or complete liquefaction.
Fluxes are substances, usually oxides, used in glasses, glazes and ceramic bodies to lower the high melting point of the main glass forming constituents, usually silica and ceramic flux functions by promoting partial or complete liquefaction. The most commonly used fluxing oxides in a ceramic glaze contain lead, sodium, potassium, lithium, calcium, magnesium, barium, zinc, strontium ...
FLUX to lower the melting point of the higher temperature ingredients . REFRACTORY INGREDIENTS are those with high melting points, such as the SILICAS and ALUMINAS. SILICA SOURCES IN GLAZE FORMULATION. SILICA is added to glazes by the addition of compounds such as: SILICA, BALL CLAY, KAOLIN, and FELDSPAR. BALL CLAY is a commonly used clay in ...
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.
