Tag #138552 - Interview #78499 (Bernat Sauber)

5 kms from Lapos there was a mine. Some people used to mine some cellophane-like, totally thermotolerant material. They brought up the pieces from the mine, and those had to be cleaned, and there were some thick pieces that had to be cut into 20 or 50 pieces, in order to attain the half a mm thickness. And they exported them. There were only two of three such places in the country. This material was mainly used as isolation, or for 200 degree boilers or melting furnaces to close the observation-slit, because at that time thermoresistant glass did not exist yet. It was quite remarkable, and one of my cousins had such an activity, and I worked there, as well, because I had no other job.
