Gloss transparent light brown/honey. Ready to use, lead free brush on earthenware glaze.
Firng range 1060°c to 1100°c
Do not shake container stir thoroughly before use
Store glazes out of direct sunlight at temperatures below 30°c and above 5°c
Do not add water to glaze. Adding water will increase the number of coats required for correct thickness.
Apply glaze using a soft brush. Apply 3-4 even coats to ensure adequate thickness.
Always fire glaze to recommended temperature.
Keep container lid clean and tightly sealed to avoid glaze dehydration.
Northcote Pottery recommends testing of all products to ensure suitability for your requirements as glaze application, clay type, firing atmosphere and glaze flow can vary greatly.
Clear low fire gloss powder suitable for raku firing. Firing range 980°c to 1080°c
Lower firing glazes have a tendancy to craze.

May be used as a source of alumina in glazes where it will have the effect of raising the firing temperature and increasing viscosity. Overloading with alumina has a matting effect. The tendency of glazes with high clay content to crawl may be reduced by the introduction of alumina as part replacement of clay. Alumina is also a useful addition to underglaze colours if there is a tendency to crawl.
The high melting point of 2050°C makes alumina useful as a bat wash.
The 100 mesh grade is recommended for use as a bat wash and in refractory bodies. The 300 mesh should be used in glazes and may also be used in bodies.

Occasionally the preferred source of alumina in a glaze because it remains in suspension for a longer time.
A ball clay with good plasticity. Fires to a light cream colour. Used in bodies to increase plasticity and in glazes to introduce alumina and silica and as a suspending agent.
Useful in bodies up to 2 1/2% to prevent scumming due to soluble salts. As a flux in high temperature glazes, barium carbonate will produce matt and semi-matt surfaces at earthenware temperatures.
WARNING: Insoluable in water. A poisonous material.
FIRST AID: If poisoning occurs, contact a doctor or Information centre.
