A Polish glass manufacturing transcription, from a German technikal journal Dingler's polytechnisches Journal 89 (1843) Band was presented. For the first time The Journal published the description and the drawings - Beschreibung des Verfahren der reticulirten venetianischen Glaser, von Franz Pohl - that is the description of the process used for the replication of the Venetian network filigree glass (in German: reticulirten Glaser) by Franz Pohl. Franz Pohl (1813-1884), of Czech origin (Neu Welt), was connected with Lower Silesia throughout his life. A master glass blower, a practitioner and an inventor of glass making techniques in the area of an industrial production of glass tableware. In the years 1841-42, a designer and a builder of the Josephine Glassworks (Josephinenhutte) at Szklarska Poręba (Schreiberhau), Jelenia Góra Valley (Hirschberger Tal), Lower Silesia. A technology manager of many years , at the Director's post of the Glassworks. Franz Pohl started to work for Preussler again in the years 1837-1841, at the Orle-Carlsthal. Cooperating with a German chemist, Dr. W.E. Fuss, he worked out a method of making the old Venetian mosaic glass - millefiori. There, he also began experiments in creating aventurine (copper) glass. It was at the Carlsthal Glassworks, in the years 1839-1841 that, for the first time, Franz Pohl made network filigree glass (vetro filigrana a'reticelli) according to his own idea. He was accompanied by German glass blower, A. Seidel. Franz Pohl, the inventor of an original method of reproducing the historical Venetian network filigree glass (vetro filigrana a'reticelli), was to the 1849 year the only glass practitioner in the whole Europe who had thoroughly published and documented, with descriptions and drawings, his own technological process of production.
