| Abstract Scope |
Many early European porcelain bodies were highly fluxed bodies that often were deficient in alumina, producing unique microstructures that are distinct of commercial and ancient Chinese porcelains. The microstructures of wares from the early history of Bow porcelain manufactory (1747–1776) possess a characteristic double corona structure, i.e., two distinct rings surrounding relict glass frit grains. The early recipe is described, albeit vaguely, in a 1744 patent. Prior recreations of the recipe, fired to high temperatures with a short dwell time, have not displayed this double corona structure. In this work, the surrogate porcelain was batched using commercially available raw materials comparable to the historical patented recipe and the double corona structures were obtained in samples fired at lower temperatures for a longer time. SEM-EDS mapping and color-based cathodoluminescence mapping reveal this fascinating microstructural feature in the surrogate. |
