Thank you so much for these answers! I'm sorry I was unable for some reason to reply to anyone. Of course, these things make sense. Now what I'm wondering is... here's the result I want to have happen. Can any of you think of a way that it might work? Picture a smooth stone block. A person lays on it. When they get up to leave, the stone is warmer than their body was, leaving a distinct thermal field another body can enter. When another body lays on the stone, that person can feel the imprint of the person before them shift into their own imprint. The stone never grows cold. Thoughts? Infrared mapping of the body to direct external heating (could this be done by warm water flowing under the stone?) If so, could the stone suddenly go very cold as well, almost frosty? Thanks for chatting me about this! PS. Exchemist - I love a warm seat. I taught skiing in Japan for many years.

I'm an installation artist who works with social interactive concepts which point at how we affect each other, even if we never directly encounter each other. I'm working on a new piece and I have some questions about heat. I am looking for a material which a person might lie on. If they were to lie still, the warmth of their body would be imprinted for a time onto this material, and if someone else were to touch the material, even, say, ten minutes after they left, the new person would be able to feel the warmth of the other's departed body with their hand. Perhaps sharply so. Were that new person to lay on this material, they would feel warm for a time, until the material had normalized to the new body. I was originally thinking of basalt stone in the sun, and how it holds and ratiates heat for hours after the sun has passed. Anyone have any ideas? Grateful for all input.
