The collection documents the level of the artistic iron casting from the early 19th century till the 1930s. The collection features fireplace ledgers and stove work, reliefs, plaques, sculptures, lights, ornamental containers, frames, inkpots, highly valued cast-iron jewellery from the latter half of the nineteenth century, funeral and building cast-iron works, kitchen wear (baking moulds, irons, mortars) and objects related to production technology (moulds, models). The oldest cast-iron exhibit object that represents the period of the first artistically rendered cast-iron works is part of a prismatic stove – a side panel of a stove from the second half of the 16th century with a depiction of the parable of the rich man and poor Lazarus based on the stove panel by Hessian carver Phillip Soldan. Among the most valuable and technically most advanced in the collection are castings of the Komárov ironworks from the first half of the 19th century coming from the time in which the ironworks were owned by the business-active Vrbna family from Hořovice.
