Jerry, oooh. That is why one should use smoker fuel that exudes a cool, blue smoke, not dark and hot. When I smoke the colonies, I ALWAYS test the heat coming out of the nozzle (is that what it is called) with my hand infront of it. If I find it really hot, I pump the bellows until the smoke is smoking good and the smoke is not HOT. Sometimes when it first fires up there is flames that come out, I just wait a little bit longer.
You will be surprised. If you pump the bellows lightly, there is not alot of heat that comes out. Test this and practice with this, you will be able to tell what temperature the smoke is.
That is why burlap is so commonly used. It provides a cool, blue smoke. I bought burlap from the hardware store, it was food grade, clean, no additives. But it burned up really, really fast. When I purchased burlap from the Honeybee Centre in a neighbouring town (a very reputable honey operation), he gave me the burlap that he sells there (well, of course). It is treated with coconut oil to keep it burning a little bit longer I would suppose. It does burn longer and does not have the toxins that gunny sacks can have. They are treated with motor oil and are toxic, would never use them. It is cautioned about the use of burlap, that it is not treated with motor oil. The palm oil is much more safe, and yes it does burn longer.
I was outside by the chicken yard yesterday and noticed a tree that had been put into a pile when we had some land clearing done. There were three trees in this pile. One of them I think was birch, it had the white bark. I remember in an old post saying that I didn't think I had any birch on my property, well, I guess that I did have one. Anyways, all along this fallen birch tree were hundreds of polypores growing along it. I have to look into the internet to see if they are shelf polypores or timber polypores or what they are exactly. But I remember in that post that got so long, think it was called "let's flame about the smokers" or something like that, the title of the thread made an impact on my mind and I remember it, that these (Finsky really liked the species that grows in Finland and lights his, once they are dried, with the cigarette lighter in the vehicle) make wonderful smoker fuels and burn for a long time. But, I think what I remember is that they are hard to light. Of course I think they would have to be dried first.
I have used the dried staghorn sumac flowers, they are awesome and provide that cool, blue smoke. Well, Jerry, I have rambled, I don't know if anything I have said has helped you out, I hope it may, if it doesn't, I think that you will still hear lots of great information from our forum friends. Have the best of a wonderful day, heading off to get kids ready for that thing called "school". Cindi
