In the field of ceramic tableware lead has traditionally been used in glazes and low melting fluxes (combined with pigments to form colours).
Cadmium has largely been used in the form of cadmium sulphoselenide pigments, to generate red, orange and yellow colours.
Cadmium can also feature in fluxes for these colours.
The paper will largely concentrate on glazes, reviewing unleaded formulations researched and giving an indication of the extent to which the UK tableware industry is converting to unleaded glaze formulations.
An initiative by Middlesex and Galway Universities, Galway Crystal and Royal Brierley Crystal will also be reviewed.
This aims to address the questions, « How safe are the elements we propose to replace lead with ? » through a programme of factory dust/volatiles monitoring and metal release testing.
Finally, the dfficulties of finding replacements for cadmium pigments will be discussed, options for retaining cadmium pigment but in a non-toxic encapsulated form will be described.
