Amber and Brown Sea Glass
Sea glass is found in various shades of amber and brown. Ok, before I go any further, the bulk of amber sea glass in Puerto Rico did not come from Budweiser bottles! The beer bottle sources are: Heineken, Beck's, India, Medalla, Tigre and some of the familiar US brands.
India and Medalla are Puerto Rican brands. Tigre is a Puerto Rican beer which is no longer made. Heineken and Beck's were bottled in amber glass in Puerto Rico up until about fifteen years ago! Malta India, a popular sugar cane soda, also has contributed to the abundance of amber sea glass there.
Clorox, Lysol, medicines and snuff use to come in amber bottles. Judging from all of the sea glass pieces I have with Clorox embossed on them I would say a lot comes from Clorox bottles. This helps to date sea glass as Clorox came in glass from the early 1900's to the 1960's. Imagine the mess from dropping a bottle!
I have a piece with a peanut embossed on it so peanut butter jars can be added to the list. The odd piece comes from old victorian windows as I have a few pieces with victorian era window patterns on them.
