Historical glass - replicas of historical glass. Handmade for us in the Czech Republic, in a historical centre of medieval glass production. The green glass, forest glass is crafted using traditional methods that have been handed down from one generation to the next in Bohemia (Czech Republic) since the 14th century. Of course, this means that it is hand blown on furnaces demanding great skill. The presence of tiny bubbles in this glass, as well as its pleasant green coloration make it unique and characteristic. Also the presence of a Pontil mark or punt mark is a trade mark for hand made glass; the scar where the pontil, punty or punt was broken from a work of blown glass. The presence of such a scar indicates that a glass bottle or bowl was blown freehand, while the absence of a punt mark suggests either that the mark has been obliterated or that the work was mold-blown.
