Oil Paint in the Freezer

I like to use a lot of paint and I hate to waste it. The paint I use is quite expensive and for creativity it is best to keep a lot of it available on your palette. I attempt to get the most out of my palette by storing it in the freezer between sessions. The freezing point of linseed oil employed in the paint that I use is -20°C (-4°F). Our freezer is set at -17.8°C (0°F) , so the oil paint does not actually freeze. The cold temperature slows the rate of oxidation and evaporation thus preserving the paint. Now if I could just convince the bride that it is "OK" to get a little bit of paint on the frozen foods....
