A device () for extracting an ingredient in a cartridge () by supplying an extraction liquid such as heated water into such cartridge, includes upstream and downstream cartridge enclosing parts () relatively movable between an open position for inserting and/or removing such cartridge and a closed position for forming an extraction chamber () enclosing such cartridge during extraction; and a cartridge handling arrangement including a cartridge holder (), in particular a holder fixed to or integral with the upstream part or the downstream part, for receiving and holding such cartridge against gravity when inserted and descending under gravity between the enclosing parts in the open position prior to forming the extraction chamber (). The handling arrangement further includes at least one cartridge positioning element (), in particular a pair of positioning elements, that horizontally guides such cartridge () upon reception by the holder () in a cartridge extraction alignment () between the upstream and downstream parts (), optionally the positioning element (s) () being fixed to or integral with the downstream part () and/or having an arched portion () for contacting such cartridge.

The invention proposes a method of locally colouring a part made of ceramic material of the metallic oxide type mainly including the following steps of taking a support for the part and a laser, able to move relative to each other in an XY plane, performing a plasma treatment of the part using a gas containing one element selected from among nitrogen an carbon, so as to convert a surface layer of metallic oxide, into a substantially stoichiometric ceramic chosen from among metal nitrides and carloides, locally illuminating the part with the laser beam so as to provide sufficient energy to cause a local change in colour by altering the stoichiometry of the surface layer, and scanning the surface of the part using the laser beam so as to form a determined pattern.
