      Stained glass windows were quite popular around the turn of the century. This looks pretty simple. I am no expert by any means, but I would value your piece at around $30.00 give or take. Probably made by a local craftsman, or as a hobby piece....

      If it were mine, I'd take it into the oldest stained glass repair firm in your area and ask them.

      Hi, me again. Just wanted to say 3 things. First, I saw your window before I saw the other one of its type, so I didn't have the info I needed for you when I posted my "Love It" verdict on your window. The other window like yours is 39 0f 39, and I've copied the response to that Collector's query below my chatter - just in case the popularity of this site has proved too much for your internet browser, as it has for mine, and you've not yet found 39/39. Secondly, your window could be rather valuable. I am only a small collector, but I know someone who collects boldly, and in his establishment, he has a window similar to yours. He liked to show me what he had, and I questioned him on that window, and the price he mentioned shocked me. I think $30 is far too low for your window at least because that kind of pressed glass is uncommon. Your glass is not the 'pebble glass' type that one sometimes finds in old arts and crafts windows at a flea market; your glass features a representational pattern excuted in bas-relief, and it is uncommon. Third, if I had this window, I'd want to move everything else out of the room, and watch the play of light on it for hours - it's that beautiful. Congratulations on your find and good taste. Now, for the informed opinions of those who responded to 39/39:

      Absolutely gorgeous antique glass tiles! Architectural art glass. Called Prism Glass Tiles.

      I think that they may be made by an art glass company, but when I researched antique glass tiles, I didn't find an exact match. Maybe someone who specializes in a certain glass company will know more.

      Here's what I did find out -- hope it helps.

      Possibly made by LUXFER -- this is what I found so far:

      From this neat glass website --

      They say: The most familiar type of prism glass is "Luxfer tiles" (actually made by several companies, like this American 3-Way Prism Company signature tile). More correctly "prism tiles", they were introduced in 1897 by the Luxer Prism Company, using Pennycuick's 1885 patent. The idea was very successful and the tiles widely used. Plain tiles without a pattern on the front are common still, as are a few patterns, notably panel and raindrop, but some are very rare. Frank Lloyd Wright penned 41 designs for Luxfer, however only one was produced, a stylized flower; fortunately, it's also fairly common.

      Then I read: -- which says:

      The Luxfer Prism Company started in Chicago on October 1896 as the Radiating Light Company, founded by James G. Pennycuick to commerialize his patent of 1882 for "an improvement in window-glass". His improvement was the addition of horizontal prisms to the back side of square glass tiles, which redirected sunlight from windows w it was plentiful, back deep into rooms w light was scarce, reducing the need for artificial lighting and light wells. Luxfur prism glass advertised that it could double the amount of light that entered a room when compared to a normal glass window.

      In 1897, Frank Lloyd Wright patented a style of prismatic glass tile designed to refract and diffuse light into the building from the outside for maximum lighting efficiency. These tiles were generally used in store fronts as the transoms to the larger plate glass display windows. The combination of magnified natural light and a highly decorated ceiling made each storefront a dazzling place to visit.

      Luxfer Prism Company, named for the Latin words lux (light) and ferre (to carry), propelled itself to the forefront of the prismatic glass market. The small panes of glass were four inches square, smooth on one side, and formed with horizontal V-shaped ribs on the reverse. The ribs were angled to throw light at a specific angle. Each pane was numbered for its specific angle of refraction that allowed the installer to tailor the direction of the flood of light. Depending on the lighting needs, a combination of prismatic panes were selected much like an optical prescription. Prismatic glass was touted as a fireproof way to light a building and was soon specified for new construction. Luxfer promoted prismatic glass as the "Century's Triumph in Lighting".

      Penn Station in 1938 was a glorious example-- the glass roof lets in sunlight which then falls through the glass floor and illuminates the tunnels below.

      thank you soooo much!! I will look into it some more - The home was in my family and I'd like to lead each panel as gifts and include a history - can't thank you enough!!

      I've seen those sorts of figured glass tiles before, but not too often. They are not prismatic since there are no prisms on the back sides; they are purely decorative. I only specialize in the prismatic stuff, so they are outside my knowledge-- sorry, I can't shed any light on who made them. I don't think Luxfer or American 3-Way did as their focus was on prismatic daylighting, and I've never seen such tiles in any of their catalogs or ads.

      If no collectorsweekly readers come up with an answer, I suggest posting your query on, whose numerous and very informed readers know everything about decorative glass.

      These sort of tiles are also mentioned in Bob Alexander's so-called "book" on glass tiles that he touts on eBay sometimes. I don't know what he has to say about them as he is persona non grata and I'm certainly not buying his "book". Bob's eBay id is "guardfrog", but in insulator collecting circles he's known as "guardfraud". Be wary!

      Okay - thanks Ian!! This is great, all the info I am getting…

      Those glass tiles were made by the Addison Glass Co.
      They made a number of designs in a variety of colors.
      A number of them are pictured in my book "A collectors Guide to Glass Advertising Tiles"

      Available from me at
      Almost all know tiles are listed in this book.

      Ian Macky? you once again proved that you don't know much about these tiles

      6.imacky, 19 months, 7 days ago
      Lo, the frog croaketh! No, I don't know anything about the purely decorative tiles-- I just collect prism glass. Bob: best of luck with your "book" which you "scanned".

      Have you tried yet? If you get more information, please post it back here!

      I know these as Addison Pressed Glass -- and I need a pane! I have a window made of them (though the center egret is purple glass) and I need an amber side pane (when I bought my 1904 Wisconsin home and had a broken pane replaced the handyman actually chipped a different pane.)
