Burnt jogre bones are the bones of jogres that have been used with a furnace or a tinderbox. This item is used in the Tai Bwo Wannai Trio quest. Jogre bones are obtained by killing jogres. Burying burnt jogre bones gives 16 experience in Prayer, or 64 experience when offered at the Ectofuntus.
Attempting to burn the bones on a fire or range will generate the message "You heat the bones over the fire, but they don't look any different." If you use burnt jogre bones on a fire you will receive the same message. If you have multiple bones in your inventory, the normal cooking window will still appear asking you how many you would like to cook.
When making burnt jogre bones, if a player selects the "light" option when right-clicking on jogre bones without level 30 Firemaking the player will receive the message "You need a firemaking level of 30 to burn Jogre bones. You could find some other way of burning them."
These bones do not give prayer points with the twisted bird skull necklace.
