Glass finishers in Lübeck's studio - masterful cutters
A decorative glass tumbler consists of two layers of glass: the inner clear layer is coated with a coloured layer of glass when still in a molten state. As the blanks are blown, the glass thickness varies. Unevenness, such as small blebs, streaks and colour deviations may also occur. The design is created by grinding the coloured layer of glass at the desired position. Carl Rotter's spherical-drilling technique has been permanently improved. Therefore, many other grinding techniques were developed, and with them more and more Rotter designs.Engraving, grinding and polishing - completing one single glass item can take up to 15 hours
Our glass finishers are the studio’s real unicums; they are irreplaceable, unmistakable and incredibly good.

“For me, glass finishing is the most beautiful way to creatively realise my ideas and to create objects for eternity. Even with my long-standing experience, I am constantly improving my technique. I immensely enjoy the opportunity to make the apparently impossible - possible.”

“The work is meditative on the one hand, yet on the other hand it varies, because every glass has different properties that I have to recognise and deal with accordingly. The colour blue, for example, is the most difficult when grinding, because it is less transparent and, when holding the glass to the grinding wheel, one has to find the exact spot - without seeing it”

“The blanks vary in thickness, the grinding techniques are different, and every colour has to be cut differently. You get a feel for it. We, the glass cutters, recognise each other's work. We all have our unique touch and 'signature'.”
