This is an old milk bottle with B.C.CO in a circle we picked up at the antique store today. The glass has a purple tint to it and is reactive to UV light. It looks to have been hand blown into a mold as it has a couple bubbles in the glass.
I have tried to clean this up but it has a cloudy film on the inside of it, that I cannot get clean. Anyone know a way to get rid of a film like this?
The 'cloudy film' is a part of the glass itself, as it was likely dug up, left outside, or in the water (probably the first/second) for a long time (it seems to, here, take 20+ years to be noticeable).
Glass with Manganese turns purple when exposed to the Sun's radiation. This can happen in the ground or after a long time in a window. I'm not sure if the radiation penetrates wooden walls, though. Put it in a sunny window. It might get darker in 10 years.
My best guess is [a city name starting with B, or a last name] Creamery Company.
Bubbles happen in fully machine-done processes too. I think I see an 'Owens' type 'suction scar' on the base. There may be words on the base too?
If American, your bottle is likely pre-1920. Do the seams go up to the top? That can help put a manufacturer on it sometimes. I think I see a horizontal seam along the mouth.
What all does it say?
Thanks for the information. I went back and looked at the bottom of the bottle and yes it did say something but it is all worn down. I can almost make out Buffalo USA on part of the bottom but the rest is unreadable.
The seam on the side of the bottle goes to the bottom of the lip. Then there is a seam that goes around the lip of the bottle.
Baby Oil will temporarily hide some of the cloudy, white staining, but it has draw-backs.
