A note on a simple device for measuring wooden artefact volume

The study deals with the development of an air displacement volume-measuring device for the estimation of the volume and calculation of the density of fragile wooden archaeological artefacts. Using a heat-sealed plastic bag as sample holder, an air pump, a flow meter, a pressure gauge and a timer, a number of steps are completed to measure the time required to fill up the bag with air of pre-set pressure with and without the archaeological object. The volume of the subject is then calculated using the empty and loaded bag filling time difference and the standardized air flow rate. The advantages of the device include its acceptable accuracy and low cost.
