So sorry to spoil this tip but it's not sap in pine cones or in wood that causes creosote. I learned this many years ago when I had a wood stove to heat a home I was renting and that same year my mom's home caught on fire caused by her wood stove chimney.
Sap is actually fuel and it helps produce more heat and it is heat that helps slow down creosote build-up. The actual cause of creosote build-up is the surface temperature of the flue. If the surface temperature of the flue is cool, it will cause the carbon particles in the flue gas/smoke to solidify.
A hot fire using 'completely dried' materials means a hot flue, and a hot flue means a lot less creosote. The draft created by the hotter fire moves the air up the chimney faster. Because it is moving faster, the flue gas does not have as much time to turn into creosote inside the chimney. But even if your fires always do burn hot, be sure to have your chimney cleaned every single spring because some creosote is going to build-up no matter what. :-)
Interesting! I soaked mine in vinegar/water then dried them in a 200* oven for 2 hours. I wonder if this process helps to get rid of that residue. I used soy wax and dried twigs and stood the pine cone in it until it set. I gave them away as gifts so I hope it worked. The recipient loved them, but I will pass this along just in case.
Thanks for the safety tip - I've just shared that on 'twitter'as I thought more should know about it.
