Basic instrument each company should have to control the temperatures during the lamination. It is very difficult to grant the reading of the temperature on the glass surface. For some simple laminations the reading of the kiln temperature is enough, however there are some interlayers requiring a more specific process with the achievement of the precise temperature and curing time. The datalogger in combination of the flat thermocouple positioned on the glass surface, can control the raise of the temperature giving the possibility to adjust it during the recipe to prevent to wait for the end of the lamination to verify whether the cooking is complete or if cooking anew is necessary.
