The Grünthal works specialised in the production of chandelier trimmings and glass jewellery rods. In 1878 Wilhelm Riedel switched the Maxdorf mill from processing flax to hemp. For seven years Josef Riedel had been travelling from Antoniwald to Polaun at least three times a week to oversee the rebuilding and later to run the glassworks.
