Re: Burning

There are various options, but if you cannot avoid the problem by better control of the kiln feed chemistry or burning conditions in the kiln then there are two possibilites: (i) install the equipment to fire Cardox charges in the region where you have persistent problems, and (ii) by an industrial gun and shoot the rings out.
