How much mineral oil do I use in a rain lamp? I have one that is about 30 inches high. Though the pump runs, no rain falls. I put in about 1 pint of mineral oil. Suggestions?

I have a large rain lamp and it didn't start working until I put in 1 1/2 pints of mineral oil.

I just started a web page of miscellaneous info about rain lamps, since I just got one myself from eBay, and such information is hard to find. Here's the link:

http://www.simnia.com/rain_lamps/

There are several things I haven't found out yet myself, like: (1) Why is glycerine often said to work in rain lamps when I can find no documentation to support that, and how is glycerine different than mineral oil? (2) Are there schematic diagrams anywhere of rain lamps, of how they're constructed, and how they work? (3) Are replacement parts available, and if so, where are they obtained? (4) How does one unclog the channels when individual fibers stop dripping? (5) What is the history of rain lamps, who invented them, are they patented, etc.?

Anyway, thanks for the info, everybody. I just came across this forum today and learned a lot already.
