At about 1 minute into this video from the Schreiber clarinet factory, several huge pressure tanks can be seen, where large baskets full of angular but drilled out pieces of wood for later machining into clarinet body parts are sunk: https://www.youtube.com/watch?v=fZQprUXwFs8&ab_channel=OmegaMusicUK
At least to me, those tanks looks as pressure tanks, not vacuum tanks. Thus no vapour, but the pressurization of the fluid inside must be to accelerate its absorbtion into the pieces of wood.
The first attached picture (in my next post below) is from a new Schreiber German system clarinet I had for trial for just a couple of weeks, "bleeding" bore oil from the surface (that happened after some time of continuous playing, when the instrument got warmed up).
The other attached picture is from my own Wurlitzer clarinet, also "bleeding" bore oil from the surface. That happens whenever I have oiled it to full saturation (the bore staying wet, not absorbing further oil), and also after some time of playing when the instrument gets warm.
In the third picture that same area is wiped clean. Interestingly it's a particularly "nongrainy" area of the body, while one could expect a "leakage" to appear at a seemingly less solid place.
I've never oiled the outside of this clarinet, only the bore. Thus, at least to me, this is proof beyond doubt that also simple post-factory oiling of just the bore not only gets the oil absorbed into the wood, but also (with fully saturated wood) gets the oil to "travel" all the way through the body wall to the outside surface (and yes, this joint is airtight as a bottle, so no cracks or similar for neither air or oil to escape such a way).
When posting these pictures a few years ago in another thread here, someone commented on them as remarkable. However, with at least German or Austrian made clarinets I think this is just perfectly normal (bear in mind also that some Buffet models are/has been made by Schreiber, with probably the same factory oiling process as for Schreiber's own clarinets).
