Small molded glass roses oil lamp.

This little oil lamp is 6.5" high with a 3.5" diameter font and 3.75" diameter base. It weighs 1 lb and 2.4 ounces. It holds 150 ml, or 2/3 cup, of lamp oil, about 5.3 ounces or 10 hours worth of oil. The font is decorated with molded roses and reminds me of goofus glass that has had the paint removed. A burner would screw into a collar mounted to the glass threads on a ring that extends out of the top of the font, and would be held in place with plaster, so this is an older oil lamp. This lamp is unusual in that the font and base are one continuous piece of glass and not glued together. It was made using a two piece mold and the mold lines extend from the bottom of the base up into the font.

This is a pretty nicely made and sturdy little lamp which I found in a thrift shop years ago and have kept in hopes of finding a replacement collar, burner and globe, but no luck, so far. I did find a similar complete lamp in an auction for which the seller was asking a stupid amount of money. The construction of that lamp and mine proves it to be an older lamp. Older lamps have a long ring coming out of the font for mounting the collar which can accommodate a lot of plaster to hold it in place. Chances are not good that I will ever find a collar and burner for this lamp, but it is still a nice piece of glass. It does have quite a few bubbles and straw marks.

It would make a nice little lamp for walking from room to room or for providing just a little bit of light in a room that does not have to be kept lit for long periods of time. I am pretty sure that it is American made. No idea of who made it, though. The example I found, shown in image #2, has a fancy burner and shade which appear to date it as a late 19th or early 20th century lamp.
