Wood? Plastics?
Do you have a specific purpose in mind?

diamonds pretty durable
it'd help if you gave more details, if you're worried about you're oven and freezer I'd reccomend oven gloves or woolly mitts.
If you're worried about volcanoes and the arctic you'd need something a bit more heavy duty

Sorry Booms, diamonds have a very high thermal conductivity, terrible insulators.
over all OP does not give enough conditions to warrant a logical answer. |

| Ok like lets say I make a box outta something to protect an object on the inside, what would insulate it from something as hot as fire, or as cold as dry ice, liquid nitrogen, etc. hope that might help out more. thanks |

I have a few suggestions. However, I must ask, what is the duration that you intend to submit this box to? The object contained within must stay at a constant temp? or will it allow slight variations? Also, is there a weight requirement on this container? or any specific dimensions that you wish to see for the insulation?

double walled vacuum insulated stainless steel jacket
..
or go buy a fire proof safe and put a styrofoam cooler inside for the LN2 part of the program.
Jeez ,why do people want specific answers to vague quetions? |

As others have mentioned, there is no answer to this because you haven't specified the requirements in sufficient detail. If you place an object, any object, inside a box and place the box in a fire and leave it there, and there is no connection between the object and the outside, eventually it will come to the same temperature as the fire. And incidentally, the temperature of the fire itself depends on a number of variables. |
