Hi! I recently purchased two salts, description was English Art glass salts w/sterling rims Sheffield England 1885. These look very similar to a salt in the Ooen Salt Compendium identified as Webb; I see no markings on the glass, wondering what the experts here think? The gold paint on the base is worn, one is worse than the other, but I think they are gorgeous. Thanks for any advice. And can anyone recommend any books on English Art glass? Thank you!!
