I saw something recently where laser ultrasonics was used to measure
wet paint thickness. Perhaps it would also work here.

: Without touching the piece, it is of major interest to know the
: thickness of the enamle coating on cast iron. The maximum thickness
: is 3mm. The key is to know this thickness at the initial
: solidification temp of 1000f...if there is to little, then he can
: add (t), this will help reduce the heating cycles and improve
: the Quality control. This system can be assemply line driven if
: proven reliable. The problems are 1000f and no contact. Emat is
: out, contact required! Mag Lift off...no! UT..2 TO 3 mm at 1000f,
: I don't know? Could Infrared be of some help or other optical
: method? This one is giving me a hard time of it!!!!
