Over the next ten years, Frederick VI visited the Carlshütte again and again. As in 1829 for example, when Holler was able to report on the first tapping of the smelting furnace. In 1831, Frederick VI visited the blast furnace construction site, and he was back in Rendsburg again in 1835. The king's fifth and last visit took place in 1839: the Carlshütte was in full swing, and Holler was able to present the king with a steam engine that was built there. The founder did not forget that the economic upswing was due in no small part to a number of privileges granted by the monarch. These included the duty-free import of raw materials, the duty-free export of iron goods, and protective tariffs against foreign products.
