I thought I'd post a simple item on lamps but my, oh, my, there is a lot to say about lamps during the 19th century. So, as time goes by I'll be posting more on lamps. But for now, here's a taste into the world of lamps.
Encyclopedia Britannica ©1824 has this to say. The link brings you to Google books and should bring you to the page. The article starts on page 207.
At the beginning of the 19th century lamps were primarily oil lamps of some sort. Argand lamps were developed during the last quarter of the 18th century. The Argand lamp included a burner and a chimney. The reservoir was on the bottom then the wick was feed into the oil.
We have a variety of oil lamps developed with this simple system during the early part of the 19th century. As the Victorian era came into vogue the lamps became more fashionable. In other words, the more elaborate the lamp the more your wealth and good taste showed to those around you. That did not negate the need for practical lighting.
Below are two images from the 1890 Encyclopedia Britannica. The first is a reading lamp. Generally as writers we might have a tendency to think in only table top lamps. But these reading lamps could stand on the floor or be mounted to a wall. The second image is of an 1838 invention by M. Franchot called the moderator lamp. This helped to pull the oil up to the end of the wick for a brighter flame.
