1. Support for an optical coating liquid composition to deposit by evaporation treatment on an optical article, comprising a crucible (35; 135) and an optical coating liquid composition (34; 134) which is introduced into said crucible (35; 135); wherein said support (30; 130) further comprises a frame (36, 37; 136, 137) forming an envelope in which said crucible (35; 135) and said optical coating liquid composition (34; 134) are wrapped; said frame (36, 37; 136, 137) having an internal space (45, 51; 145, 151) and being configured to hermetically seal said crucible (35; 135) and said optical coating liquid composition (34; 134) when said internal space (45, 51; 145, 151) has an internal pressure (P) lower than a predetermined pressure threshold (Pth) and being configured to let out vapour of said optical coating liquid composition (34; 134) when said internal pressure (P) of said internal space (45, 51; 145, 151) is greater than said predetermined pressure threshold (Pth); by virtue of which said support (30; 130) constitutes a cartridge of optical coating liquid composition (34; 134). |
