The Paint Detective

Patrick Baty

Sampling

Small samples are taken from each of the elements

The best of the samples are selected and placed in moulds with

a label to identify them

The paint flakes are placed in half-filled moulds. Quick-setting resin is poured

over them, and they are left to harden.
