As we see here in the first diagram, it seems that yer valve gear is intrudin' on yer sand pipes and the steam- powered whistle done fogged up the cab windows. Which is causin' excessive heat in yer chimney.

So you're saying there's a shimmy in my cowcatcher?
I don't see there being an appreciable difference in the temperature of the smoke due to bowl thickness. I do think the conduction heart adsorption of a thick briar is going to be superior to convection cooling due to the minimal amount of air flowing around the outside of the bowl. I agree smoking technique is the primary factor in having a cool smoke.
Another pipe myth seemingly eternal that retailers use to sell pipes.
A larger diameter bowl would only push more volume of smoke if you took larger draws. This isn't the case. My point is that the rate through the stem is constant; therefore, the rate through the ember is a dependent variable which is inversely related to the diameter of the bowl.I concede that the delta in temperature as a result of fluid velocity might be negligible and noticed only by the most sensitive of tongues; yet, a pipe with a larger chamber diameter would push more volume of smoke through the hole and it'd travel faster than it would in a pipe with smaller chamber diameter. The pipe smoking system is nothing but a Venturi tube:
The problem with that is that the entire surface of the pack doesn't remain constantly ignited and the ember burns down an inverted cone not adhering to the bore of the chamber necessitating tamper usage to guide the unburned tobacco to the warmer center of the pack to be burned.
The previous post I commented on suggested that if I draw 100mL of smoke at 50mL/sec through stems with identical draft holes, it will move faster out of the stem if the bowl is wider because venturi effect.
As for the cone theory, the same volume of air moving through a wider cone will be moving slower, and therefore not be burning as hot.
All this chatting and yet, the next time I read someone say they had a “cool smoke”, I won’t know if they mean the smoke in their mouth or the bowl in their hand.
So if a hot chick is smoking a cool pipe, is she hotter than a cool chick that's smoking hot?
Actually I prefer pipes with thinner bowl walls, mainly because this relates to lighter overall weight ,and Yes, often times bowl surface on my estate pipes with thinner walls seems to get hotter quite easy and unexpectedly but I'll take that as indicator to slow down my smoking cadence
Not really a theory since the force of the draw is going to be strongest at its place of origin and as the ember is drawn to that point it is starting from an area less pull to greatest. My last post was just bait really to see if you just wanted to argue, it's just a pipe, not high school calculus.
We were all theorizing, brainstorming what possible things might account for the mystery. It seemed to me that my ideas got shut down when I was only trying to contribute to the conversation.
I was trying to figure out if you were a troll or an idiot. I guess I know which it is, now. You're apparently intelligent and a dick.

Hey, Iraisch! (damn auto correct wants to make you Irish - as you have likely dealt with)
This is a common challenge students in thermodynamics wrestle with: what state is the system in at time-start?
IF you've already saturated the bowl to its heat capacity, THEN a thick-bowl will be a more stable heat sink, and would support your hypothesis (not addressing the bowl diameter/draft hole challenge).
IF you're beginning a smoke (which I took for this situation), THEN a thicker bowl will be more of a 'heat suck,' or, as we're circling around, deliver a cooler smoke (all things being equal).
I wasn't connecting the dots (being new to the forum), but the OP is Road-to-Pines, and his challenge in assessing what made sense is embedded in your question. Do thicker bowls offer a deeper heat sink to cool the smoke, or is it the other way around, do they serve as insulation? I should have addressed that more clearly at the beginning. Your post helped!

Unfortunately, I am looking more and more like that avatar! I now do have a very white beard, though no fedora. And days of wearing a suit coat are far behind me.
I will focus on the word "nuggets" and be well chuffed. Thanks.
Yes, yes, yes! But not discernible except by highly calibrated equipment, or a man with a palate and brain far superior to most of us.
