Hello all, I just joined up and love the fourm, I have been around old bottles for some 45 years, having dug with my dad, and caught the bug in the 1970's, I like the sun tinted bottles, and have many in my collection, many people say its wrong to tint a bottle, that it distracts from it being true. My Dad had a tree he would put clear bottles on and in a few years they would turn, he also placed tin foil on roof and placed bottles there. My question to the fourm is my Dad built this box out of cardboard and lined it with tin foil, he had a light inside that I dont remember what kind it was? not sure what he used for a bulb?, it tinted clear bottles very fast. My Dad has passed away and I would like to try this again, to honor his memory, I would place a few at his grave site, Do any of you know anything of this method? I have searched the net with no luck. I also always wondered just how old the bottle has to be to tint, it seems that I have some as late as the 1930's that have tinted?. sorry for the long winded ramble, and many thanks for letting me join fourm.
