Is it safe to use Pigma® Microns on tableware or glassware?
• It is not advisable to use any product on tableware that may come in direct contact with food that has not been tested and cleared specifically for that use. • Pigma Microns are not permanent on glass. You would have to test the effect of putting glaze over them on a practice piece to see if that seals them satisfactorily for non-tableware; • Our inks have not been tested for use on tableware that comes into contact with food. We do not recommend that they be used in that manner.
