As a manufacturer of ceramics, you must issue a declaration of conformity to your end customers upon request, with which you certify that your ceramics are intended to come into contact with food.

 

First of all, it is important that you know whether the glaze you use contains lead and cadmium compounds (regardless of whether it is a label-free or a label-obligatory compound). If this is the case, you will find the desired information for each of our listed glazes. Even if you choose a glaze that does not contain any of these compounds, it cannot be ruled out that lead and cadmium can get into your ceramics in other ways (e.g. through fumes from the kiln lining). In other words, you have to measure the possible migration of lead and cadmium on the basis of the ceramics you have manufactured. This testing has to be carried out in an accredited laboratory using instrumental analysis ! A simple derivation based on our information regarding lead and cadmium content is unfortunately not legally permitted  !

 

If you have received a positive result from your laboratory regarding lead and cadmium solubility (according to 84/500 /EEC), then you are entitled to issue a declaration of conformity according to EC 1935/2004.

 

This declaration of conformity has the following structure:

Of course, the laboratory reports must be kept for traceability. In addition, you should make sure that your glazes are acid-resistant and that there is no optical wear and tear with long-term use. In principle, a declaration of conformity would also be possible for glazes that are not acid-resistant, but customer complaints are inevitable!
