The term Forest glass or the German name Waldglas is given to late Medieval glass produced in North-Western Europe from about 1000-1700 AD using wood ash and sand as the main raw materials and made in factories known as glass-houses in forest areas. It is characterised by a variety of greenish-yellow colours, the earlier products being often of crude design and poor quality, and was used mainly for everyday vessels and increasingly for ecclesiastical stained glass windows. Its composition and manufacture contrast sharply with Roman and pre-Roman glass making centred around the Mediterranean and contemporaneous Islamic glass making to the east.

Famous quotes containing the words forest and/or glass:
“The partridge and the rabbit are still sure to thrive, like true natives of the soil, whatever revolutions occur. If the forest is cut off, the sprouts and bushes which spring up afford them concealment, and they become more numerous than ever. That must be a poor country indeed that does not support a hare. Our woods teem with them both.”
—Henry David Thoreau (1817–1862)
“Shall we with pains erect a heaven of blue glass over ourselves, though when it is done we shall be sure to gaze still at the true ethereal heaven far above, as if the former were not?”
—Henry David Thoreau (1817–1862)
