Mercury mirror with Mylar film overlay

On one web page automobile motor oil was suggested in lieu of mercury. I
have not been able to find the overlay liquid used by the Canadian
University Laval in Quebec; it is quite possible that none is used, since
they discuss skimming the surface to remove debris, at least on their
gallium-indium amalgam mirror. I would suggest emailing the project for
details.

Hi Gordon and mirror folk,
I just thought that someone might know the oil they use to cover the
mercury with so that it could be experimented with in the ceiling
sundial situation in order to have a safer flat, level mirror.
