Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below Earthâs surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles and other minerals.This mineral composition usually gives granite a red, pink, gray or white color with dark mineral grains visible throughout the rock.Granite is the best-known igneous rock.ranite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles and other minerals.

This is dry, air, almost absent of humidity. Each year we know that egg production will drastically decline and that a heat induced molt is coming. The molt is not really from the heat but from the stress it places on our flock, so technically it is a stress induced molt.
Cos if you throw them in a fire they will burn, of course the wooden part usually lights up at the same time so that's a chicken and egg type example. It would depend on the specific matches composition and structure as to what amount of friction energy will ignite it. And if you meant how hot is the flame on a match; that'll depend on the composition of the match head and the material used for the stick. So 'a high temperature' is the answer.
