However, this and other problems often settle after two weeks of feeding. Stress or anxiety can cause difficulties with breastfeeding.

Refractory initial bake-out of a new refractory lining on site can be a very expensive and time-consuming component of a refractory repair project.

If an entire repair is made with a prefired system, then normal furnace start up schedules can be used, without the fear of steam spalls or other damage during the initial heating. Bake-out of multi-component linings, which may include a combination of precast shapes and other materials placed in the field, can often be reduced by the
