Flat axes to socketed axes, palstaves, and founder's hoards.
Bronze Age tools follow a famous sequence: flat axes, then flanged axes and palstaves (with a stop-ridge and side flanges), then socketed axes with a loop — each stage a casting innovation. Spearheads go from tanged to socketed with graceful leaf blades; rapiers and leaf-shaped swords follow; and personal items include pins, razors, and gold ornaments.
Casting tells: look for seam lines from two-part moulds, casting jets and flashing on unfinished pieces, and the glassy dark or green patina of long burial. Founder's hoards — buried scrap, ingot fragments ('cake'), and broken tools together — mean deliberate deposition, not casual loss.
Hoards and precious-metal finds trigger treasure law in many places; report before cleaning. Record type and stage (flat, flanged, palstave, socketed), dimensions and weight, and mould seams; the typology is well published and a confident stage assignment is usually possible.
