When kilns are not candled long enough
This picture has its own page with more detail, click here to see it.
Candling of kilns is the final stage of drying. Driers cannot achieve the temperatures needed to remove all water, so almost all industries rely on early stages of firing to remove it fully. Failures like this are part of the learning curve of every company (because there is always pressure to fire as fast as possible).
Although much more common in heavy clay industries, porcelain insulators are one of the less likely products for this to happen with. This is because machine-forming methods make it possible to use aluminous porcelain bodies having very little clay. Thus, faster drying (with less shrinkage and fewer residual internal stresses) also makes it possible for early stages of firing to be quicker. But there are limits. These insulators are solid, thick and heavy. And they have extreme variations in thickness (thin skirts to solid spindle). So, for even these, early stages of firing must be conducted carefully. For such products, periodic firings of days is often needed.
