Benicia Iridescence and Patina on Bottles – Not a Sick Bottle
09 February 2012 (R•041614)
I wanted to start a collection of pictures of bottles with Benicia iridescence and/or patina. Please send me examples of bottles you have or pictures in your archives.
I asked prominent West coast collector Mike Dolcini for some pictures of sick bottles from his extensive background of material that he has collected, found or dug and his response was “DUDE, that isn’t sick, it’s that beautiful “Benicia” iridescence. You never remove that. Some collectors pay a premium for it”.
This made me smile. Of course I know that the bottles are not sick but I suppose in my email haste I used the term ‘sick’ thinking it sufficed for the tough to spell words “Benicia”, iridescence and patina.
You know, when I woke up as a child and was green or purple, and my runny nose was crusted up, my mom thought I was sick?

Photos of pieces of sea glass which has this “benicia iridescence” even though they have been worn by the sea. Perhaps they obtained this patina after, and not during active tumbling in the ocean…Clyde Smith, Canada

Ive always been under the impression that Benicia glass is a certain form of mineral decomposition in the glass creating an abalone type iridescence and build up to the glass. Not just the typical sick or rainbow decomposition we are all familiar with with the majority of dug bottles? Ive seen what I thought to just be “sick” glass called Benicia while now and then there’s been a bottle called Benicia that really popped, took on a whole character of its own. Not having ever held anything that was surely benicia glass I wonder if Ive been misled, by myself?
There was also a large tannery in Benicia and the acidic effluent from the tanbark oak used in the process were allowed to run freely into the bay. That really colored ’em up. Not much left to find, but occasionally a real gem pops up. It was drilled heavily in the late ’60s and ’70s. I stopped going several years back. Too darned filthy. Give me a dirty, crap infested outhouse any day. Guess I’ll dig one tomorrow.
