Update for 'Metal Release from Ceramic, Glass and Enamel Ware in Contact with Food' Guide

Lucideon has pulled together information from across the globe for the latest version of its cross-industry reference guide, which sets out details on the safe use of ceramic, glass and enamel ware in contact with food

'Metal Release from Ceramic, Glass and Enamel Ware in Contact with Food' has been updated for 2022, indexing the rules relating to worldwide regulations and standards across more than 90 countries and/or economic areas - listing the relevant test methods and toxic metal migration limits in a simple and concise table.


The guide has provided a single point of reference for testing facilities and ceramic, glass and enamel ware manufacturers since its launch in 1972. It is also an invaluable resource to exporters, importers, retailers and glaze or colour producers looking to ensure their products conform to relevant international requirements.

Authored by Lucideon's Environmental Scientist, Joanne Dawson, this latest version replaces the 2018 publication and features amended entries including those required by Colombia, Ecuador, Indonesia and UAE.

Joanne Dawson said: "The book explains how coloured glazes applied to ceramic, glass and enamel ware could contain heavy metals such as lead or cadmium that may be released to varying degrees.

"The amount of migration from the ware to food is dependent on the composition of the glaze, temperature at which the ceramic was fired, type of food and duration of product contact.

"Compliance testing of decorated ceramic and glass ware must be carried out for toxic metals that are used in some colours and glazes.

"This is done to establish not only safety, but conformity with the legally allowed maximum levels of migration and to ensure continued consumer protection."

The new version of the guide is available in electronic and hard copy formats, priced at £695. To purchase a copy or for further information, please complete the form below or contact Joanne Dawson, +44 (0)1782 764245 or
