indonesian traditional stove

Indonesian society since antiquity cooking using wood with stove from clay or brick. until now there are still many people who still use wood stove to cook food daily needs, although they already have a gas stove that is more modern, clean and easy. especially the villagers who still use it. one factor is the abundance of waste wood materials / tree twigs.
my grandmother who lives in the countryside is still faithful to use this wood stove.
