Re: vaseline glass production in Japan

Welcome, it would be nice to hear about vaseline glass production in Japan.

I (Ritsuo) is a manager of the Japan Uranium Glass Collectors Club.

I am glad that you are interested in vaseline glass production in Japan.
Several years ago, the Vaseline glass Museum opened in Japan.
I guess this is the only one museum in the world, which exhibits vaseline glass only.
Its formal name is the Fairlywood Glass Museum.
(Uranium reminds the atomic bomb for most Japanese, and they do not use
the name of Uranium glass museum.)
They are not only showing vaseline glasses, but also they are producing new
vaseline glass using the uranium mine near the Museum.
You can buy them in the museum shop.

>>all the streetcar lights I have seen, it is the reflector along the back surface that is made from uranium glass

Recently, I knew that US street cars were using this type of head-light.

>>The lens in the middle works and in bright sunlight, you can concentrate the sun enough to start a fire

This is very interesting story.
Why did they need to use vasleine glass for lense? (clear one might be more effective?)
I could not find the article of CORNING MONEX on the web.

It clearly says MONEX.
The embossed rim says:
CORNING MONEX REG U.S. PAT. OFF  MADE IN U.S.A.   10" D X 2 F . I. D.  P A T 12 - 9 - 13

THE 10" D X 2 F I.D. most likely refers to 10 inch inside diameter.

I have never found any information on it either, but have never tried doing a patent search either.

I have no idea why it was made.  my speculation was is that it was a caution lens for alongside the railroad tracks, not necessarily a lens for a train or trolley.  The United States used lights on the side of the track to let the engineer know if it was safe to proceed.  However, this purpose is also a speculation.

  If you go to www.vaselineglass.com, the VGCI logo at the top of the page is a neon light our club made with corning uranium tubing.

 :o I think you meant www.vaselineglass.org, perhaps a moderator  :srn: can fix your post. .com is a site run by a different Dave  8)

you are absolutely right.  Heck, I am the WEBMASTER for that site!  I must have been pretty tired when I wrote that post.  
it is www.vaselineglass.org, not vaselineglass.com

>>it says CORNING MONEX

I (Ritsuo) am a manager of JUGCC(Japan Uranium Glass Collectors Club).
One of our club member owns a similar lense, and he says this is a part of a signal lamp (PL: Position Lamp) of US railways.
It can forcus the light to a long distance by its lense.
I could find similar explanation as follows:
>http://www.railroadsignals.us/signals/pl/pl.htm
>1915 - Dr. William Churchill of Corning Glass developed a pale yellow "fog-penetrating" glass, which the PRR then used in their PL signals.

Thank you!
I always figured my lens was for the railroad, but did not know if it was for a signal, or on the train itself.  I now have proof!
