From then on you need to grow the light into a proper flame by blowing oxygen onto it and catching your material on fire.
Transfer it to a bed of lightly piled sticks for airflow, then put a handful of similar sticks on top until those catch too.
Add bigger sticks for bigger flame until you are putting on logs.
tip on firemaking; sticks the size of your thumb are good for a quick fire enough to boil water. Logs the size of your arm will provide about 1 hour of fire for heat, good for camp. Anything bigger/more of the same will be a bonfire and that is good for big camps and scaring away wildlife.
