r8rfan121 Posted October 25, 2009 Share Posted October 25, 2009 Hey everyone, So I'm fairly new to hookah, and i heard something from a friend of mine that which side of the tin foil is facing down could make the shisha burn? anyone had any experience with this, or have noticed whether shisha smokes better with the dull side up or the dull side down? Or does it not matter at all. Link to comment Share on other sites More sharing options...
NIGHTS OF BAGHDAD Posted October 25, 2009 Share Posted October 25, 2009 honestly ive never tempted faith so i always do shiny side down.. Link to comment Share on other sites More sharing options...
fineout Posted October 25, 2009 Share Posted October 25, 2009 the fact that one side is shiny isnt for any reason its only because of a manufacturing process...it doesnt matter either way or change anything at all Link to comment Share on other sites More sharing options...
r8rfan121 Posted October 25, 2009 Author Share Posted October 25, 2009 fineout, thats what i was thinking but i wasn't sure if the shinier side wouldnt somehow do something with the heat. I tried both ways last night and didnt notice anything but i figured it worth asking Link to comment Share on other sites More sharing options...

This means that the heat from the tobacco is reflected back onto itself 8% more than if you did dull side down. Link to comment Share on other sites More sharing options...
fineout Posted October 25, 2009 Share Posted October 25, 2009 meh, 8% isnt that much and i do both and never notice any difference Link to comment Share on other sites More sharing options...
fineout Posted October 25, 2009 Share Posted October 25, 2009 and reflecitivity is an optical property,not a thermal property. hookah smoking is convection heat not optical heat so i dont think it actually does anything Link to comment Share on other sites More sharing options...

Also, if your shisha touches your foil, the smooth (see shiny) side will offer better conduction due to better contact.On the other hand, the difference are soooo damn small, that it doesn't matter a damn bit.

foibled again Posted October 25, 2009 Share Posted October 25, 2009 There are three methods of heat transfer: conduction, convection, and radiation. Reflectivity affects thermal radiation which is insignificant in coals. Conduction and convection are the two major means of heat transfer in this case.

ryno Posted October 25, 2009 Share Posted October 25, 2009 Have I noticed a difference in either side? No. Do I keep the shiny side down out of habit? Yes Link to comment Share on other sites More sharing options...
Twisted Posted October 25, 2009 Share Posted October 25, 2009 I was told shiny side down. I think I put it that way without even realizing it because I never look at the foil to see if its shiny or not. lol. Link to comment Share on other sites More sharing options...
Scoop Posted October 25, 2009 Share Posted October 25, 2009 if you dont put shiny side down, your hookah will melt from the coal radiation going outwards. your face may melt off too. Link to comment Share on other sites More sharing options...

Arcane Posted October 25, 2009 Share Posted October 25, 2009 i usually have the shiny side facing down...i don't make it a conscious point, but it usually happens that way. also, if the shiny side is up...the coals make weird "burn" marks...and it just looks weird...

Sonthert Posted October 25, 2009 Share Posted October 25, 2009 I don't think it matters in terms of the amount of heat (or negligibly so) conducted. Conduction doesn't rely on reflectivity. Convection, on the other hand might affected, but in a negligibly small amount, again. Conduction is the key principle here, unless you are one of those weirdos that like to suspend the charcoal over the bowl so it doesn't touch the foil. I do shiny side down because I think that that shiny side up would be more likely to create a momentary flash or glare that might cause an oopsy. I believe in the lost books of the Bible that one of the commandments that didn't make the final cut was "14. Thou shalt put the shiny side of the foil down."

ih303 Posted October 26, 2009 Share Posted October 26, 2009 Ha! Interesting stuff.I too have tried both ways and have noticed absolutely no difference. Link to comment Share on other sites More sharing options...
king_lunchb0x Posted October 26, 2009 Share Posted October 26, 2009 this exactly what they say on http://www.reynoldspkg.com/reynoldskitchen...amp;cat_id=1337Which side of Reynolds Wrap® Aluminum Foil should I use, the shiny or the dull side? Actually, it makes no difference which side of the aluminum foil you use—both sides do the same fine job of cooking, freezing and storing food. The difference in appearance between dull and shiny is due to the foil manufacturing process. In the final rolling step, two layers of foil are passed through the rolling mill at the same time. The side coming in contact with the mill's highly polished steel rollers becomes shiny. The other side, not coming in contact with the heavy rollers, comes out with a dull or matte finish.so i would conclude that their is no heat difference or else they would have stated using shiny side in or out for best results.
