Abstract
A method for measuring the melt temperature in a melt vessel, where the vessel wall, at least partially, is made of a material transparent for infrared light; said material, at the interior of the vessel, is coated with a material having a high and stable emission factor (e>0.5; de/dT<0.001); the temperature of the inside of the vessel wall is used as a measure of the melt temperature close to the wall; and said temperature at the inside of the vessel wall is measured by use of optical pyrometry applied from the outside of the melt vessel.
