Hi Jim,
That huge glass dial looks really handsome and a fine successor to
the Spectra glass tradition. As it appears to have a horizontal VI/VI line I
assume that it is true south facing?? The half hours before and after VI/VI
puzzle me somewhat though.
Kind Regards,
Tony M.

Subject: Oklahoma State sundial
Hello All,
Occasionally I work on larger sundials, and a couple of years ago I designed a
large glass sundial for a new research center building at Oklahoma State
University. It was nearly 6’ x 9’ in size, a glass sundial to be mounted on the
curtain wall on the south façade of the building. I never visited the site
since it is quite far away, so I did the job remotely, including the initial
declination determination.
Up until now I have not had any good pictures of the dial in situ, but this
weekend a Spectra customer who recently visited the site sent me a link that
documents the dial quite nicely:

This was a unique project where the dial had to be mounted very high up on the
building, and the dial face and time shadow needed to be visible at a very low
incidence angle from street level, almost directly below. The dial also had to
be visible from blocks away and it is located very near their large football
stadium…and meeting these two requirements made the project quite challenging.
The dial plate is laminated glass with a special interlayer and the primary
surface is sandblasted to receive the shadow and overcome the reflection of the
sky when viewing from a low incidence angle.
I hope you will all enjoy having a look...
Best,
Jim Tallman
