I believe it will read the target. I was doing the same with the roast in our oven, was able to measure the temp difference between the meat and metalwork inside the oven through the glass door. Think of it like a light meter, if you point it at a bright light source inside a glass, or inside a lesser "glow", it will measure the most intense light. -Roman -- http://www.piclist.com hint: The PICList is archived three different ways.
