The House Reveals it's First Artifact

This bottle was found behind the kitchen counter as the plumbers were running the water line for the reefer. We have no clue as to what this bottle was used for or how old it is, so if anyone knows please leave a comment. We were thinking probably a medicine bottle of some sort. It has a cork stopper with a long metal pin attached. The bottle still has a white powdery substance in it (think BC powder) that is now clumped due to age and moisture.
