You are a treasure hunter. I love the variety in your findings. The pipe bowls are very similar (identical) to the pipes I have found on the Thames, London. They are dated, roughly, by the size of the stem. Yours have thin stems so they may be from the 17th century. Fatter stems are later...
I love the outcome. I have cleaned bottles the old timey way with fine sand and water just shaken by hand. It is not close to your results, though. Exactly what grit and supplier do you use? Thanks, Kathy
