Transferred FV into bottling bucket with 1 pint of wort with 3 leaves of galantine melted in it, check bottles after a 10 days conditioning and looks like yeast or something is clinging to side of bottles, picked up by the neck and span between my fingers and in seamed to lose its grip and fall like very fine dust to the bottom?
Should I do this to all 40 bottles

or will this settle as time goes by, never seen this before and this is first time I’ve used galantine, apart from that its much clearer than its been before at this early stage.
