Water smithy – punching of a stamp

The sound of manual punching of a stamp on hot steel. The recording was realized in the historical water smithy in Gdańsk (Oliwa district) constituting the department of the Museum of Technology in Warsaw.

Stamp ornaments were used for decorating flat surfaces. Recorded sound refers to the strokes of piston in the form of a hammer embedded in a wooden handle. Pistons in the form of a steel bar (with the length of 10 – 15 cm) narrowing downwardly were also used. Pistons were finished with a stamp in the form of a curve, star, circle or other ornamental element.

The water smithy in Oliwa was in operation from at least 1597 to 1945. Not every type of steel was suitable for processing with the use of water power, that is why manual forging was also performed in the smithy. The facility is equipped with two stoves in which the hearths are located very low, as the processed pieces of steel weighed even up to 250-300 kg. Due to their weight, they were picked up with blacksmith tongs and transported to the forging post by 4 – 6 blacksmiths. Depending on the dimensions, the process of heating a piece of steel in the stove could last from several minutes to a dozen hours.
It is estimated that tools for manual forging used in the water smithy in Oliwa were manufactured in the late 19th or early 20th century.
