Polishing Compound

Polishing Compound

Usage conditions apply
This cylindrical glass jar with a leather stopper came from the shop of Henry Fitz (1808-1863), America’s first successful commercial telescope maker. The top of the discolored paper label has an image of a brick factory. The text reads: “SULPHATE OF QUINIA / POWERS & WIGHTMAN / Manufacturing Chemists / PHILADELPHIA.” Despite the label, the jar probably contains a polishing compound.
