manganese dioxide toxicity

Chronic Manganese poisoning may result from prolonged inhalation of dust and fume. The central nervous system is the chief site of damage from the disease, which may result in permanent disability. Symptoms include languor, sleepiness, weakness, emotional disturbances, spastic gait, recurring leg cramps, and paralysis. A high incidence of pneumonia and other upper respiratory infections has been found in workers exposed to dust or fume of Manganese compounds. Manganese compounds are experimental equivocal tumorigenic agents

Manganese is not toxic

CWilliams - I don't know where you got the idea that manganese is toxic, but it is not. Neither manganese metal nor manganese dioxide are toxic. Look at the MSDSs, for instance. Manganese dioxide - Manganese -

Not food safe!

Manganese is extremely toxic. Never use this glaze on functional ware, and do not let your skin come into contact with the wet gaze - use rubber gloves.

Low Fire Gold is a Low-Fire Ceramic Glaze Recipe.

What is a Low-Fire Glaze?
Low fire glazes are usually fired in the range of Cone 06 to Cone 04 (1828 degrees Fahrenheit to 1945 degrees Fahrenheit). Because of their low firing temperature, low-fire glazes are able to hold much brighter colors than high-fire glazes. They also have a wide range of finishes including glossy, matte and specialty surfaces like crackle and crystal. The low firing temperature of low-fire glazes has a down side. Low-fire glazes are much less durable that higher fired glazes and it is difficult to have a low-fire glaze that is safe for food.

Low-fire glaze recipes are usually developed for use in electric kilns. Electric kilns are much easier to control that gas kilns and they provide a much more even source of heat. This allows potters to control low-fire glazes much better than high-fire glazes.

Electric kilns normally do not have dampers to control the oxygen levels inside. There is usually a constant stream of oxygen being pulled into the kiln. As a result, when pieces are fired in electric kilns they are often referenced as being fired in an oxidized atmosphere.
