Beschreibung

This was to be used as a source for other lapidaries until at least the Renaissance. Theophrastus classified rocks and gems based on their behavior when heated, further grouping minerals by common properties, such as amber and magnetite, which both have the power of attraction.[50][51][52] He also comments on the effect of heat on minerals and their different hardnesses. He made the first known reference to pyroelectricity, noting that the mineral tourmaline becomes charged when heated. He also considers the practical uses of various stones, such as the minerals necessary for the manufacture of glass; for the production of various pigments of paint such as ochre; and for the manufacture of plaster. This work is noted for being systematic and is comparatively free from fable and magic. CONDITION 238 pages. Copy is bright and crisp with unworn DJ in protective sleeve. The only slight faults are occasional spot to edge and slight tape ghosting to rear ep where DJ cover has been taped to fit. Size: 8vo - over 7¾" - 9¾" tall. Bestandsnummer des Verkäufers 14592
