This book addresses the contributions made by analytical chemistry to the characterisation of 18th and early 19th Century English and Welsh porcelains commencing with the earliest reports of Sir Arthur Church and of Herbert Eccles and Bernard Rackham using chemical digestion techniques and concluding with the most recent instrumental experiments, which together span more than a hundred years of study. From the earliest experiments which required necessarily the sacrifice of significant portions of each specimen, which may already have been damaged , to the latest experiments which needed only microsampling or the non-destructive interrogation of valuable perfect specimens a comprehensive survey is undertaken of more than twenty manufactories of quality porcelains. The correlation is made between the quantitative elemental oxide determinations of the scanning electron microscopic diffraction and Xray fluorescence data and the qualitative molecular spectroscopic Raman data to demonstrate their complementarity and use in the holistic forensic assessment of the origin of the fired procelains ; this will form the groundwork for the adoption of analytical techniques for the attribution of unknown or questionable procelains to their potential source factories . The book will also examine the perception of what constitutes a porcelain and its definitions and examines the assignment of porcelains to types which currently employs the definitions of hard paste , soft paste , hybrid , magnesian and bone china from the conclusions derived from the analytical data and a consideration of the raw materials employed in their manufacturing processes. During the discussion of this analytical evidence several themes and protocols have been established for its utilisation in the potential identification of porcelains and several case studies undertaken for this purpose are cited. The book will be of interest to analytical scientists , to museum ceramics curators and to ceramics historians.

The material for this book arose from the author’s research into porcelains over many years, as a collector in appreciation of their artistic beauty , as an analytical chemist in the scientific interrogation of their body paste, enamel pigments and glaze compositions, and as a ceramic historian in the assessment of their manufactory foundations and their correlation with available documentation relating to their recipes and formulations. A discussion of the role of analysis in the framework of a holistic assessment of artworks and specifically the composition of porcelain, namely hard paste, soft paste, phosphatic, bone china and magnesian, is followed by its growth from its beginnings in China to its importation into Europe in the 16th Century. A survey of European porcelain manufactories in the 17th and 18th Centuries is followed by a description of the raw materials, minerals and recipes for porcelain manufacture and details of the chemistry of the high temperature firing processes involved therein. The historical backgrounds to several important European factories are considered, highlighting the imperfections in the written record that have been perpetuated through the ages. The analytical chemical information derived from the interrogation of specimens, from fragments, shards or perfect finished items, is reviewed and operational protocols established for the identification of a factory output from the data presented. Several case studies are examined in detail across several porcelain manufactories to indicate the role adopted by modern analytical science, with information provided at the quantitative elemental oxide and qualitative molecular spectroscopic levels, where applicable. The attribution of a specimen to a particular factory is either supported thereby or in some cases a potential reassessment of an earlier attribution is indicated. Overall, the information provided by analytical chemical data is seen to be extremely useful for porcelain identification and for its potential attribution in the context of a holistic forensic evaluation of hitherto unknown porcelain exemplars of questionable factory origins.
