Adding Weight to Oud with External Materials: How Do You Detect Artificial Heft?

Because oud is often sold by weight, raising the weight becomes a tempting goal for adulteration. We saw oil-soaking, and here we take up the more general form: adding weight with external materials, such as inserting heavy materials into the cavities of the piece or soaking it in mineral solutions. In this article we show these methods and how you detect artificial heft.

The forms of adding weight

Alongside oil-soaking, there are other methods for raising the weight artificially:

• Internal filling: inserting heavy materials (like metal, lead, or clay) into the cavities or cracks of the piece, then hiding them at the surface.
• Soaking in mineral solutions: immersing the piece in solutions in which metals deposit that raise the weight.
• Deliberate moisture: selling wood not well dried so it stays heavy with water, and its weight drops after drying.

All these methods target the scale, in the hope that the buyer will be content with the absolute weight without reading the rest of the indicators. But artificial weight, like oil, does not come from real resin, so it contradicts the scent and the appearance.

How do you detect artificial heft?

Read the weight in the context of the rest of the indicators, not alone:

• A heft that contradicts the scent: an apparent heft with a weak scent under gentle heating is a strong signal; a natural heft is accompanied by a depth of scent.
• Inspecting the cavities and cracks: examine the piece for a material inserted into its openings or holes plugged with a foreign material.
• The internal cross-section: at breaking or seeing the cross-section, a foreign material may appear that does not belong to the wood.
• Weight change with drying: if the heft is from deliberate moisture, the piece's weight drops after storing it in a dry place.

The same rule we have repeated: weight is a strong indicator but is misled, so it is only read with the scent, the cross-section, and the feel. Natural heft from resin is testified to by its scent, and the artificial is exposed by the rest of the indicators.

What do you do if you are in doubt?

Never rely on the absolute weight in gauging quality; rather read it relative to the size and with the scent. If you doubt a heft that does not match the scent or the appearance, ask to see the cross-section and inspect the cavities, and do not pay the price of a dense oud for a heft whose source is filling or metal. And it is better to buy oud from a source that shows its indicators transparently. And in the following articles we move from physical intervention to deception in the description, the first of which is grade-mixing.
