The technique of "fluo engraving" was developed and perfected between 1905 and 1908 by the Muller brothers.
This technique consists of attacking the glass with hydrofluoric acid.
On a very opaque white background, two other layers of glass - duck blue and midnight blue are superimposed.
The decoration is acid-etched and finished with a grinder.
