This series consists of transparent glasses without opal glass content. Most of the colorescent glasses of the factory Wissmach consist of one or two colours plus clear. The different colour parts are mixed and folded with colourless glass mixture and then rolled out to a sheet. This is how the unique design gradient is created in each sheet. With a product so demanding in terms of craftsmanship, it is to be expected that not every sheet will look the same - the colour distribution varies just as much as the colour intensity. This characteristic is not a defect, but is precisely what gives this glass its natural character.
