One common method to test if something is made of lead is using an X-ray fluorescence (XRF) analyzer. This portable device can quickly determine the elemental composition of an object, including the presence of lead. Another method involves using a lead testing kit, which typically involves swabbing the object with a testing solution that changes color in the presence of lead. Alternatively, you can consult a professional laboratory for more accurate and precise testing.
