Composition of Crystal Glass Made in the Middle of the 19th Century at the Gus-Khrustalnyi Factory

Аннотация

This is the first study of a crystal glass composition, as well as its thermal and spectral (Raman spectra and fluorescence) characteristics, produced at the Gus-Khrustalnyi factory in the middle of the 19th century. The sample studied is a potassium-calcium glass with a low lead content. The formula for such a composition was first developed in Central Europe in the second half of the 17th century and then improved at the beginning of the 18th century. The possibility to use a portable XRF spectrometer to analyze historical glass is demonstrated.
