A rural oil factory. About one and a half kilograms of liquid fat could be obtained from ten kilograms of flax seeds. Four oilmen worked here, each of them setting in motion one of the four powerful pestles (on the right), which crushed the grain until it turned to pulp. The pulp was mixed with a small amount of warm water and roasted in a cauldron. After the water had evaporated, the oilmen wrapped the still hot pulp in sheets woven from wool and hair. They worked quickly because the warmer the pulp the greater the amount of oil you can press out of it. The readied parcel was put into a press pushed by wedges driven in from the side (this was done by large rams mounted on two sides). Oil leaked through channels carved in the wood into a waiting vessel. The dregs taken out of the press were usually processed again. Nothing was wasted: the leftovers were dipped in warm water and added to the feed of hens, cows and pigs (and were also used for medicinal purposes) The entire oil mill on view was transported from Ochotnica Dolna and rebuilt in the Museum by Stanisław Giblak and Andrzej Plewa, inhabitants of that village.
