Flashed glass

This type of specially produced mouth-blown sheet glass is given their tint not simply by adding colour to the batch. Their colouration is created by means of the flash technique: The clear or tinted carrier glass is over-laid with one or two layers of coloured glass thus opening almost unlimited possibilities of variation.

Unlimited Variations
Glass variety

Consequently, multicoloured „flashes”, even curves and slight shadings as well as cloudy and „torn“ open glasses can be produced.

White milk glasses of opaque or opal quality which allow light to shine through but prevent inquisitive eyes from invading people’s privacy offer another large field of applications.

Production

As a molten gather, the substance later to be called „flash” is first brought to the blowpipe. Here the shape is instrumental in bringing about the appearance of the flash. A round balloon produces a uniform flash, a pearshaped gather creates a shaded flash, and small notches a torn flash. The molten carrier glass is then applied over the small gather and blown into a cylinder shape. During the process of blowing, the appearance of the flash is kept under control.

After completion of the glass cylinder, the remaining stages of production are identical to those of the Clear and Coloured Glasses.

The shaping and colouring process of the flash requires deliberate control, experience and craftsmanship on the part of the glassblower.

Technique and colours

The size of a sheet is approx. 60x90 cm (24" x 36"), its thickness is approx. 3 mm (1/8"). All the sheets are supplied with their edges intact. Small variations in the dimensions occur due to the handmade production of the individual sheets. Due to the special annealing process, the Lamberts Flashed-Glasses are easily cut and processed.

The Flashed-Glasses vary greatly in shape and colour and are available in an almost unlimited variety of styles.

Their classification ranges from the uniform flash with minimal shading, cloudily shaded and torn flashes to multicoloured milk glasses and a special collection of striped Streaky-Glasses.

The illustrations are only intended to give a first general impression of the various possibilities of flashed glass. The size of the individual sheets is approx. 60x90 cm (24" x 36"), the thickness is approx. 3 mm. Unfortunately, the printing technology does not allow exact color representation.

Sample projects

Louis Vuitton | Paris

    Project: „Inside the horizon“
    Location: Fondation Louis Vuitton, Paris
    Artist: Olafur Eliasson
    Studio: Glaswerkstätten Hein Derix, Kevelaer
    Material: 43 stainless steel steles, aluminium, LED light system, mirrors; on one of the three sides a special overlay of LambertsGlas® lemon yellow was applied to variants of coal-amber base glass; rhombus shapes without a joint sealed with SilGel®
    Object size: 5,4 x 5,2 x 91 m

    Inside the horizon COLOR AND EMOTION

    Olafur Eliasson’s “Inside the Horizon”, which was developed especially for the new Fondation Louis Vuitton in Paris designed by Frank Gehry, adds 43 triangular columns to the colonnade opposite the museum building. Two sides of each column are clad with mirrors, while the third consists of yellow glass tiles and is illuminated from the inside.

    The work stretches along the whole length of the colonnade and offers a lively play of light, shadow and reflections, as well as constantly shifting perspectives.

    St. Nicolai Church | KALKAR

      Project: St. Nicolai Church
      Artist: Karl-Martin Hartmann
      Studio: Glasstudios Derix Taunusstein
      Location: Kalkar, Germany
      Scope: 22 elongated church windows

      Colored glazing - Art towards the sky

      Clear images, such as depictions of saints, are sought in vain when looking at the big windows of the Catholic St. Nicolai Church in Kalkar. After more than 22 years, this glazing project has now reached completion. The Wiesbaden biologist and artist Karl-Martin Hartmann redesigned the hitherto unadorned church windows.

      As motifs, apart from his own artistic forms, he used images and graphic representations from nuclear physics and astrophysics, including Feynman graphs, depictions of three-jet events and deep sky images captured by the Hubble telescope. The new contemporary windows enter into a tangibly harmonious dialog with the medieval features, including nine late Gothic altars. The 22 large church windows combine the historical form of representation with the latest insights into the genesis of the universe, forming a unique reformulation of the history of creation.

          Color in motion: „Sail“ by @mahbuba.maqsoodi

            Mouth-blown flashed glass for the Munich project by Mahbuba Maqsoodi!

            --

            The wall installation made of light and color takes the viewer with it in its dynamics and at the same time invites you to quiet contemplation on fundamental questions about your own being and the world.

            An empty room in the newly renovated Missio Munichhen office building inspired Mahbuba Maqsoodi to create her work entitled “Sail”.

            The artist with Afghan roots and a very eventful life story created a permanent wall installation made of glass, which now welcomes missio visitors in downtown Munich.
