Description: | Incomplete Medieval steelyard balance, cast in copper alloy. The steelyard would have originally been comprised of a pivited bar with two unequal arms. Only the longer arm of the balance survives. The rectangular arm is oval in cross section, with a worn break at one end and a pointed conial terminal knob at the other. Along the narrow edges of the bar are a series of notched lines. The notches would have been used to position a counter balance, used to measure the weight of an object/powder suspended from the now missing shorter arm. One edge has 17 notches spaced at approximately 3.5mm to 4mm intervals, with the opposite narrow edge having two notches, one approximately 27mm from the terminal, the other a further 27mm along the length of the bar. The notch closest to the terminal partially extends around the bar on one side. On the opposite side (the wider surface) there are three diagonal incised lines with a fourth line across them, resembling a tally. The bar has an even green patina, with a small amount of iron corrosion adhering to the surface. The bar is 73.25mm long, 11.17mm wide and 10.05mm thick. The terminal knob has a maximum width of 22.54mm. It weighs 22.54 grams. | Format: | text/html | License: | http://creativecommons.org/licenses/by-sa/3.0/ | Publisher: | The Portable Antiquities Scheme | Rights holder: | The Portable Antiquities Scheme | Subjects: | archaeology | Temporal: | 1300
