This beautiful old stein was mouth-blown of crystal glass into a very elegant shape around 1870. It was colored in bright ruby using "flash" method very common in 1850 - 1870. It was then cut to clear with a stone wheel to create beautiful optical effects. This very simple but quite interesting technique was done by a skilfull craftsman with exterme precision so the effect is quite astonishing! The lid is pewter with clear glass inlay.
