I made this for myself and the server im running with a couple friends, it is reused code from https://news.kalataka.ru/show/mod/180 (If the author wants me to I will take this down, I just haven't seen a lot of updated mods that affected burn times of coal and wanted to share this.)
This basically just makes a variety of burning consumable last a lot longer for ease of use

If you want stacks of a certain rescource (like charcoal) to burn longer then I recommend this mod (Coal specific burn time) https://news.kalataka.ru/show/mod/22009

This is a SIMPLE Json patch mod so this should work even after the release the mod is said to work with, and maybe even releases before this one but test at your own risk!
This is my first Vintage story mod, I appreciate all of your support!

V0.0.4 Changelog:
            Made firewood burn 10x longer, download 0.0.3 if you do not want this feature

V0.0.3 Changelog:
            Allowed the ability for lava to be picked up with a bucket (May or may not work, I haven't tested yet)
