I let me uncle know what everyone said it probably is and he said he's surprised he's not dead. This being he said that the rubber seal had been disintegrating over the years that's why you can see flakes floating around in the picture, that the rubber seal that had been disintegrating into the bottle and he had just been re-sealing the sides with glue. He said he moved it into another location not near his house and will call some officials tomorrow on what to do with it. He's not too concerned in the meantime as he has had it on his shelf in his bedroom for the last 50 some years and nothing's happened yet.
Thank you all for the responses he was actually planning on opening it and switching the contents to a more secure container, that's why he actually showed it to me to see what his next "project" was. You all probably saved a life so I really appreciate it!Well, that would have been bad. Glad it worked out all right.
