On the third of April I acquired a vintage yellow/orange Carlisle from a vintage shop in my town (see my photos)-- now I can say officially that I have a collection of lamps!
My 25 watt that came with my first lamp, a new Lava brand from Target, wasn't hot enough, and the wax half-way melted into these weird positions and I was worried that it had semi-petrified. But I bought a 40 watt bulb and all is right with the world. It chugs away happily all day (it just sent up its first plume of the morning).
I do wonder though, before I had turned it on for the first time, the wax was rather flaky and in pieces. When melted, it has lots of little bubbles. Do you think the previous owner had manhandled it and the wax chipped? What are the signs of an effort to replace cloudy liquid? The liquid is as clear as day but the cap will not come off at all.
