wow, this is a dream
item of mine! It's stunning!
I collect Peloton glass & have 26 examples; a variety of vases, baskets, bowls, a preserve jar, a toothpick holder & a single epergne, but I have not been able to get a fairy lamp in Peloton. You are very lucky indeed!
Peloton glass is one of the rarer types of Victorian art glass. It was first patented on October 25, 1880, by Wilhelm Kralik in Bohemia. He was working for the Harrach glassworks at the time.
See this link for more details:http://www.glasscollector.net/Peloton/Harrach%20Peloton.html
Now, there are a number of variants of Peloton glass. As you can see from the above article, the Harrach type seems to mainly feature the single-colour threads on clear glass, sometimes with enamelled designs.
There are other types of Peloton feature multicoloured threads on opaque white or coloured cased glass (like your wonderful fairy lamp). There is also Peloton with satin finishes, overshot finishes, & the thread colours can vary from candy-coloured pastels to bright reds, oranges & blues. Sometimes the threads stand out proud from the surface, creating a distinctive texture, while on other pieces, they are totally marvered in & smooth.
There are (yet to be conclusively proved) theories that Peloton glass was copied by glassmakers in Stourbridge (eg. Thomas Webb, Stevens & Williams, Boulton & Mills) in England, & the Mt. Washington Glassworks in the U.S.
These pieces are believed to be the some of the ones with coloured threads on opaque white or coloured glass. However, this is still only hearsay. Until a catalogue of the time comes to light that feature Peloton glass by any of these fims, these theories about English & American Peloton glass will remain just that-theories.
Harrach was apparently not the only Bohemian maker of Peloton glass, either. Other firms (as yet un-named) copied it, & this probably accounts for the many variations in the technique, finish, & colour of Peloton items. My opinion is that most Peloton glass has a Bohemian origin, but I do believe that it is possible some of the great Stourbridge glassworks produced it too. There are a few Peloton items I have obtained from English sellers that do have a Stourbridge "look", in terms of their very fancy designs which are to be seen on other products of the same era from these glasshouses.
Sorry if this has not been much help! Peloton glass is very little documented & just as rare. My love for it seems only increased by these factors, however!
Congratulations on obtaining this wonderful piece, & if you ever tire of it, you know who to get in touch with!
