SEAGLASS CONTEST WINNER - SHARON HIRSCH 

     These are pottery shards from Hudson Bay and the local shore. I am not versed in pottery - but they are quite old.

     The bottle neck looks to be over 100 years old.

Sharon tells me that it has a lavendar color. This is clue #1 for aging the piece. Between 1880 - 1915 manganese was used in the manufacture of clear glass bottles. They used it to mask out the aqua and green from iron and other impurities. Over time and sun exposure the manganese turns lavendar.The shape of bottle neck also gives us a clue. According to Richard LaMotte's Pure Seaglass - the shape of the neck verifies that it was made between 1850 - 1920.  Fun Stuff Huh?!
