Is it hazardous to move oil and water color paintings in an unheated
trailer in below freezing weather?

<Moving paintings in freezing temperature.

Paintings are easily damaged if not maintained at the correct
temperature. The frame, canvas, paint and varnish expand and contract
at different rates when the temperature and humidity is varied. This
can cause cracks in the paint or varnish.
Acceptable temperature and humidity levels are as follows:
Winter ? Temperature 65-70 degrees F. Relative Humidity 40%-45%
Summer ? Temperature 70-75 degrees F. Relative Humidity 45-55%

Ideally a professional mover should be used who has climate controlled
vehicles. These services are offered by the following companies:

A tip to add to your oil painting knowledge
I took some lessons from a lady who used styrofoam plates as palettes
when painting and when she finished for the day she simply put another
plate, of the same size of course, over it and taped it on the sides
in a couple of places with masking tape and stuck it in the freezer.
This might work for you if you are not mixing an enormous amount at a
time. They work good as palettes since they do not absorb the oils in
the paint and they are easily and quickly disposed of when you are
finished with them and they are cheap!
