Our core production facilities and technologies include kiln casting, fusing and thermoforming. We are also working with our partners hot shops to produce blown glass and special custom made colored glass in form of blocks and rods used for our castings. We cooperate with top quality coldworking, sandblasting, acid polishing and metal workshops. Our technologies are based on more than 600 years of tradition in Bohemian glass as well as on contemporary technologies as 3D printing, CNC, water jet and laser cutting.
TECHNOLOGIES

Kiln Casting, Fusing & Thermoforming
Mold melted glass or kiln cast glass is a technology known by the ancient egyptians and similar technologies are also known as Patte de Verre or sand casting etc. In Czech Republic it was developed and became world wide known in his own form, especialy through the exceptional work of the world famous artists couple Libenský–Brychtová.
In cooperation with renowned artists and designers we manufacture, produce and assembly state-of-art architectural glass objects such as: glass walls, artefacts for facades, wall coverings, glass columns, windows, reliefs, fountains etc.

HOT SHOP – CUSTOM GLASS COLORS
In cooperation with our partners hotshops we develop special glass colors for our casting projects and also produce a wide range of blown decorative objects, chandeliers and bespoke drinking collections, using various forms of hot shaping and mold blowing.
