  ## History
  
  ### Founding
  
  An entrepreneur Jozef Schreiber founded the company in 1892 as the last and the biggest glassworks of Vienna’s company Schreiber und Neffen, who had the most modern equipment of the time. The company in Lednické Rovne is the most successful Slovak glassworks and the only one left (2017).
  
  It started by the manufacturing of flat glass, later pressed glass under Kaiserkristall brand that the company established as the first in Austria-Hungary. This was popular at the turn of the century for price and the fact that it imitated products of luxury cut lead glass. The goods were sold under the name ’’Imperial Crystal’’. Besides the pressed glass was manufactured hand blown glass under RONA Crystal brand focused on drinking glass and sets for hotels, medical institutions, cafes… as well as domestic glass for a household.
  
  Besides clear glass, the glassworks is known for its decoration techniques such as cutting, engraving, guilloche, painting, spraying, screen printing, tampoprint (an automatic calibration by laser), and pantograph technology. The company in Lednické Rovne established pantographs of English production as the first in Europe in 1896. In the 1940s, the company cooperated in the development of decors with professional designers Vincent Hložník and Martin Benka.
  
  Archived collections show products from the beginning that were decorated, full-colour pieces, along with functional designs of clear, plain glass. These lines were developed by patenting of a new handmade technology. Pulled stem, even more in 1956 than currently, is an indicator of glass products from Lednické Rovne.
  
  The history and production of the company was documented by many specialists in their publications; historians and publicists such as Jan Bárta, Ján Mondok, Eduard Toran, Igor Didov, Karol Hetteš, Jindra Bakošová, Agáta Žáčková, Jarmila Račeková and others. Likewise articles in special magazines such as Glasrevue, Sklář a keramik, Sklárske rozhledy, Umení a remesla, Arte Regalo(Spanish magazine), Tableware International, Offrir International, and Casastile (Italian magazine).

  | 1998 | The automatic line was put into operation for the production of vases and decanters by blow-blow technology. |
  | 2001 | The plant created the world's unique know-how by starting automatic line with so called pulled stem technology. This technology in combination with blow-blow process was for the first time in the world applied in the glassworks RONA. This success contributed significantly to the current achievements and reputation of the glassworks. |
