Carmo, Vapo-Cresoline was like modern day Vicks Vapo rub. There was a small oil lamp with a metal dish on top that you put the vapo- cresoline in and lit the lamp. The heat from the lamp apparently filled the air with the vapors from the product which I think relieved congestion. I have a Vapo-cresoline lamp in the box that came out of anold house in my town. I wish I could send a picture but I'm not that computer literate. If I can I'll get my son to post a picture.
would it make a big difference in value with a pat date of july 94/ or different size? I was wondering if these bottles were considered as a poison with the bumps on them. I have 2 smaller ones, one with the 1894 date and one with 1895, the bigger one is also a 1894 pat. do you know if they are all aqua? I think i have lower part of the lamp out in one of my several unsorted boxes from a different find. I'll keep busy all winter researching the boxes of stuff i havent gone over yet!
As I remember the only cresolene bottles I ever dug or saw were clear. It's a long time ago so maybe I'm wrong. I never kept any of them because they weren't valuable.
