Can you reverse compound warmth with pewter?

In chapter 73 it said  that wax burned one of his metals to keep himself warm. This metal is presumably pewter. this would mean you could burn pewter to keep yourself warm while storing warmth, right?

Pewter makes you more resistant to temperature extremes, but burning metals in general give a feeling of warmth
