I just discovered cold wax medium and would like to use it to seal some of my artwork, mostly alcohol ink and mixed media. However, I participate in outdoor art fairs, and of course, the air temperature can get really warm, even under the shade of a canopy. Could the wax get soft or melt?

Hi Nanci,

I suppose it is possible if it got really hot or in direct sunlight.  The only complaint I ever had was once someone was transporting a large painting in New Mexico in a truck that got very very hot.  It damaged the painting.  We are talking like over 120 degrees F.  It isn't really supposed to melt until 140, but I think it can soften especially to take finger prints or impressions.  It is something to consider.  

I would say the vast majority of people that worry about this have had no problem and no need for worry, but I think it is a good idea to be careful with these paintings just as you would with a traditional encaustic painting.  Use common sense and avoid extreme temps.
