Explore the purpose of inspection, weighing and material testing.

Assessment begins with the item: its form, visible marks, construction and condition. Accurate weighing helps establish a starting point.

A suitable testing approach depends on the object and the question being answered. Non-metal parts, plating, solder and mixed materials can affect interpretation.

Online photographs can support initial guidance, but final conclusions require physical inspection and verification.
