overfired

At this point overfiring begins, as is shown particularly by the volume curve, which indicates decided bloating, so that at 1450°C the clay has about the same volume it had at 1050°C before vitrification took place. At 1450°C it is, therefore, decidedly overfired. However, its excellent burning behavior is apparent from the long temperature range.

Overfired grills, or salamanders, can, in addition, be used for making toast and salamandering. They have the heat source above the food …. This may comprise sets of burners firing below refractory or metal frets, or surface combustion plaques.
