Quick Summary

Waldglas, meaning "forest glass," is a type of green glass historically produced in Germany. This glass was made using potash derived from burning forest vegetation, a tradition that likely dates back to Roman times.1

Waldglas was often characterized by its beautiful color and was used to create distinctive German glass shapes. Notable examples include cylindrical beer glasses called Krautstrunk (cabbage stalk) and wineglasses known as Römer, which featured a cup-shaped bowl on a prunted hollow stem. This style of wineglass remained popular for centuries.1
