These two items are the most important to have.
Having the proper setup and burning practices will only be as good as your wood! Too wet or too dry of wood will create smoke. 15-20% moisture is the sweet spot.
This is what I use to break wood down into kindling and 3” width pieces for really clean burns.
Gloves help when you’re handling/breaking down wood and tools for tending the fire.
Hearth screens help to keep any pieces of coal that fly away from the wood on the hearth. You want to get something light weight.
Fat wood, Duraflame starters and other wax covered wood works perfectly. You’ll also want a lighter or matches to get them started.
