Yes indeed, the emerald green ones are the Merchant Chemist bottles from Buffalo. Some American bottle glass colours are fantastic - a lot of variety. I found that one 3 hours north from the border - amazing how far products moved in the pioneer era - buggies with wooden treads running over corduroy roads for mile upon mile - makes my kidneys ache just thinking about it!
I'm fortunate that many of my best finds likely spent a good portion of their hibernation in clean sand, then were exposed, making them quite clean from the outset. For others, it's mostly good ol' fashion elbow grease, a wide assortment of brushes, copper bits for shaking,
I also use many of the tools (brushes. bent l shaped L wire ,copper bits , sand etc )And I sometimes allow them to sit with cleaning agents such as Simple Green or an orange citrus acid cleaning solution .But in the end it just takes a lot of time and generally a combination of methods to get them really clean Plus I also admit that depending on where you find them some are in a mostly clean condition from the start
