could an pile of powder of some substance (such as silver or some kind of powedered poison the wizard has seen and used before) be considered a single object for the purposes of minor conjuration, or could i at most summon in 1 grain of such material? can minor conjuration be used to create a vial with liquid in it, or a pouch containing some powder, or would the magic only be capable of creating empty container? becuase if we can indeed then what is to stop me from ether using this feature to get infinite dosages of essence of ether to assist in abducting random people or using it to create the powdered silver nessesary to make an infinite supply of holy water using the ceremony spell?

Whatever you create with minor image is only an illusion, it has no substance and cannot be used for anything else of the sort that you want to do. That being said, a pile of something, although not in itself an object, would not for me be beyond the spell, because you are not creating or manipulating anything real, just an image.

 dude i am not talking about the spell minor illusion, i am talking about the class feature for conjuration wizards known as "minor conjuration" gained at 2nd level, this does not help whatsoever
