I bought these bottles at an antique shop. Both said "Circa 1830, Found of the coast of Barbados". Anyways, I just want a second opinion of the age and any info on these heavy black glass bottles.
"Here's what it says about it, Bottles aren’t often found just lying on the ocean floor — divers need sharp eyes and a instinct for discovery. This early 1800s wine bottle was found by veteran diver “Ram” Edghill when he noticed an odd coral formation. Thinking it might be a conch, because of its humped shape, he dove down to investigate and turned the “conch” over to reveal the bottle embedded in the coral. Photograph by Eric Young"
I'd say they are close to that age, Look up types of pontils on bottles that will help you, the pontil is the bottom and bottles were made differently through the ages, and the applied top tells that it was before 1880's Nice and they are black glass "very old". lots of good early bottles have been picked up in that place at stores.
