All Beer Steins are made of Stoneware, all glazes are lead free and food safe.
Beer Steins come in three weights:
Light weight: can be used as tall, extra large, heavy coffee mugs or light weight steins.
Medium weight: these are slightly lighter than the heavy steins, but still have at least a 1/4 to 3/8 inch thick wall.
Heavy weight: 3/8 to 1/2 inch thick walls, heavy, averaging 3 to 5 or more, pounds apiece.
