Hadeland Glassworks was founded in 1762 on land belonging to the Mo farm. Initially production consisted mainly of bottles, chemists’ jars, medicine bottles and items of household glass. In 1852 Ole Chr. Berg took charge of the glass works, and introduced production of lead crystal pieces, including wine glasses, bowls, dishes and vases. During the 1800s the glassworks mainly copied designs from other European countries, but in the 1920s it began developing its own designs.
