His new material conducts heat almost perfectly, in one direction.
One major downside, however, is that it doesn't conduct heat well.
The heavier the pan, the more evenly it will conduct heat.
Hydronic systems use either hot water or steam to conduct heat.
Copper was a good candidate because it is superior at conducting heat.
Compared to other metals, it does not conduct heat well.
Important to use small not large pieces of glass, plastic or wood, because those materials conduct heat quite slowly.
Some windows, it seems, are good at conducting heat or cold from inside to outside and vice versa.
The denser a material is, the better it will conduct heat.
Stainless steel does not do as well, but is better at conducting heat than glass.
