95% of all the industrially produced flat glass today is made using the float glass process. In this process, molten glass is continuously fed into a bath of molten tin. Due to its lower specific weight the molten glass floats on the smooth tin surface, and on a long tin bath forms a uniformly thick and extremely smooth film. The glass side that faces the molten tin is slightly contaminated with tin, which has corresponding effects on subsequent float glass processing steps such as coating of the glass surface.
For the further processing of float glass it is therefore important that the surface that is contaminated by the tin bath can be distinguished from the so-called fire side (fire polishing, during float glass production the glass side facing away from the molten tin is heated)..

| INLINE Color Measurement of Paint Through a 15mm Thick Inspection Glass
Usually the color checking of color paint during production primarily is done in a laboratory. A paint sample is taken, and the color of this sample is then checked by way of a thin paint layer in dry condition. This process of course takes some time, time in which paint production might run out of the permissible tolerances and thus might require time-consuming and expensive follow-up treatment.
