Beschreibung
Zusammenfassung:	The invention provides a support for an optical coating liquid composition to deposit by evaporation treatment on an optical article, comprising a crucible in which said optical coating liquid composition is introduced; wherein said support (30) further comprises a frame (36, 37) forming an envelope in which said crucible and said optical coating liquid composition are wrapped; said frame (36, 37) having an internal space and being configured to hermetically seal said crucible and said optical coating liquid composition when said internal space has an internal pressure lower than a predetermined pressure threshold and being configured to let out vapour of said optical coating liquid composition when said internal pressure of said internal space is greater than said predetermined pressure threshold; by virtue of which said support (30) constitutes a cartridge of optical coating liquid composition.
