I found this in the surf on the island Ixtapa Gerrero mex can anyone I identify the glass age and use ?
(Dublin Tx usa)
Brown glass from the pacific
These tiny brown bottles are a mystery to me. There are remnants of identical brown bottles on the back side of this rock. There coral and seashell fragments inbedded in this rock. I hope someone can tell me the approximate age of these corked bottles and the purpose of them. Also possibly the origin of this brown glass.
