On the second floor the visitor will find himself in the laboratoty of the 1950'-ies. We can see the table of famous chemistGéza Zemplén, a gas-jet heated drying wardrobe and a number of other original objects.

One of the most interesting objects of the exhibition is the GIER computer mostly used for the supervision of chemical processes. The Danish device was used by the Pét Nitrogen Works for the evaluation of the parameters of its Ammonia department. The computer was produced in 1966.

It is proven that chemical activities were carried out in the Carpathian Basin even before the Hungarian conquest. The gold-mining of the Roman Empire was continued by the descendants of the Hungarians. There was metallurgy, expoerts were experimenting with alloys and the control of refineries and the mints.

The exhibition demonstrates the history of our chemical industry between the two world wars. The first part introduces those local and foreign scientists, whose work fundamentally determined the development of chemistry and chemical industry. It delineates the new conditions made after the disunion of the Austrian-Hungarian Monarchy and the plans of Hungary made for the chemical industry development.
