Vendor for Flint Glass Block or Prism

[Dan LaSota]

Hi,

I'm trying to put together materials to demonstrate the Faraday Effect. I need to locate the supplier of some flint glass (glass with lead oxide or similar materials increasing the Verdet constant), that I could use in my lab. I had found this from Mansion Schools: http://www.mansionschools.com/prisms-science-laboratory-flint-glass-block-for-faraday-effect-br-u8474060-light-and-optics.html

but they are not shipping until May 8 for some reason. Does anyone have another source?

Thanks.

I will give them a call tomorrow, but I don't think they have what I need. The page you linked to has a series of achromatic lenses, some made with flint glass, but they are not the correct shape. I'm looking for either a block or rod of glass at least 25mm in length.

If you know what you're doing, you can try here:

You could also try contacting Schott directly, although they may not want to deal with small orders.
