Alumina Oxide Calcined 1 Kg Crank wax-resisting

wax-resisting

It fires 1120°C-1280°C and gives toasted buff in oxidation and warm speckled orange buff under reduction

In the presence of zinc oxide

Suitable for oxidisation and reduction firing (due to the large particle size of the grog some ‘spit out’ may be observed)

Great for creative artists when cutting Art Rollers into smaller segments

Alumina Oxide Calcined 1 Kg Crank wax-resistingAlumina Oxide Calcined Alumina Oxide is an intermediate oxide, and is used to stabilize fluxes and glass formers that compose glazes. It is calcined and ground to 325 mesh. Melting point 2040C The use of too much alumina can cause a dry appearance in glazes, too little will allow the glaze to be overly runny. Lack of alumina in glazes can also result in glazes being soft and venerable to degradation from culinary acids. Its use in small amounts also
