  1. Is there a material with such a low thermal conductivity that it would take hours for an ice cube to melt?

  2. Is there a correlation to the thermal conductivity of a material and it’s electrical conductivity? Or is it the exact same?

  3. The thickness of the plexiglass is larger, and the (steady state) thermal resistance is going to be linearly propotional to thickness, so not exactly a consistent comparison. Also, there are transient effects at play, so the specific heat and density of the materials is a factor (which can be lumped together with thermal conductivity in the form of the thermal diffusivity).
