Can a metal detector detect porcelain?

I can't.

Working principle of cermet detector;

Based on the principle of electromagnetic induction, the rapidly changing magnetic field is generated by the coil through which alternating current passes. This magnetic field can induce eddy currents in metal objects. The eddy current will produce a magnetic field, which will affect the original magnetic field and cause the detector to sing.

Porcelain can't produce magnetic field, so it can't be detected.
