7 Some terms will need explanation: with the chisels, the cutting edge will expand out from the shaft in a ‘flare’, and may itself be ‘straight’ or curved. With the double-axes, the ‘wedging-grooves’ are a pair of grooves, one each side of the shaft-hole and on the main axis: they are assumed to have held cross-pins that were driven into the handle. ‘Rsh’ and ‘Osh’ denote a round and oval shaft-hole respectively.

12 In an ideal bronze, frozen in equilibrium conditions, the maximum solid solubility is 15% tin, which shows how far from ideal normal solidification is.
13 As a rule of thumb, the full effects of annealing can be achieved by heating up the metal to some 30% (if pure) or 50% (if an alloy) of the appropriate melting point.
14 Hardness testing is measured in Vickers units (HV). The process consists of impressing the sample with a diamond tip of known size and under known pressure (the variables within the system are appended to the HV: thus HV1, HV2.5, and so on), and measuring the size of the resultant indentation. The resistance put up by the hardness of the metal sample will affect the size of the indentation, and a value is obtained by reading off this against a table.
