Újmassa Blast Furnace

More information

The Újmassa blast furnace is one of Hungary's most important industrial monuments and is considered a rarity even in Europe. Interesting fact: The charcoal-fired furnace stands on four corner pillars, with a base size of 9.5×8.5 metres. It is built from rubble stone and has a squat, two-tier truncated pyramid shape. On the three sides open to the hillside, there are basket-arched vaults. Air was blown in through the openings on the eastern and western sides, while tapping occurred at the northern opening. The corner pillars were reinforced with steel tie rods. The furnace was 11.4 metres high and had a volume of 22 cubic metres. Its average daily production was 1,300 kilograms, with a batch weight of 5,600 kilograms. The waterwheel operating the four-part bellows had a diameter of 7 metres, and the bellows worked at 16 strokes per minute. The blast furnace was rebuilt in 1832. Next to the blast furnace, on the banks of the Garadna stream, stands the building of the Massa Museum, where visitors can explore the most significant events and documents of the ironworks' history, as well as the period tools and products used and made there.
