The Ti-Tri Caldera Cone -- The Ultimate Ultralight Stove System?

Is the Ti-Tri Caldera Cone the ultimate ultralight stove system?

Hyperbole?  Am I existence a petty "over the top?"  Maybe.  But perchance not.  Let's banking concern check it out.  At the halt of the post, I'll verbalize over why I recall this triple fuel arrangement is thus darned useful that I actually create consider it the ultimate lightweight stove system, particularly for mixed elevation (above together with below the elevation where fires are permitted) backpacking.
The Ti-Tri Caldera Cone inwards woods burning mode.
Well, to larn started, we're going to require a pot.  All Caldera Cones are designed to agree amongst a item pot.  The Caldera Cone shown inwards the photograph inwards a higher identify volition alone agree an Evernew 1300ml titanium pot -- unless past times strange coincidence there's only about other pot out at that spot amongst the exact same dimensions.  Check the Trail Designs website for which cones volition agree amongst which pots.
An Evernew 1300ml titanium pot
Now, notice that inwards the championship of this post, I refer to today's stove arrangement as the Ti-Tri Caldera Cone.  "Ti-Tri?"  What the Dickens does that mean?

Well, "Ti" is brusk for "titanium" together with refers to what the cone (not necessarily the pot) is made out of (titanium), together with "Tri" refers to the fact that this is a triple fuel stove system.  This stove arrangement volition run on iii fuels:  alcohol, hexamine (e.g. ESBIT), or wood.  Now, if you've seen my previous posts on the Caldera Cone (see links at the bottom of this weblog post), those were all aluminum cones.   Aluminum Caldera Cones volition warp together with or melt if they larn also hot, thus you lot tin alone terminate depression rut fuels similar alcohol or hexamine inwards them.

On the other hand, titanium cones tin handgrip rut only fine.  With a titanium cone, you lot tin terminate wood.  Why powerfulness burning woods live an advantage?  Burning woods is an payoff because you don't receive got to send it on your back.  I mean, recall most it:  When was the terminal fourth dimension you lot saw fuel-grade alcohol welling upwardly out of the ground?  When was the terminal fourth dimension you lot picked fuel off of the ESBIT tree?  The betoken existence that if you lot utilization alcohol or hexamine, you're non by together with large going to discovery it out on the trail.  You receive got to carry the fuel amongst you.  Wood on the other mitt is ofttimes available from your surroundings.

In today's weblog post, I'm primarily going to verbalize over woods burning using a Ti-Tri Caldera Cone.

OK, let's opened upwardly up that pot nosotros saw before together with run across what's inside.
The woods burning components of a Ti-Tri Caldera cone
Inside is the cone all rolled up.  Note that my cone is a "Sidewinder" type cone which is a lower slung cone that volition agree within the pot.  If you lot purchase the "Classic" type cone, you'll require to send something similar a Caldera Caddy to concur the cone.  See What "Color" is your Caldera? for to a greater extent than data on the cone send options.  Note also that the grate, wire roll, together with cone usually come upwardly amongst Tyvek stuff sacks to foreclose scratching.  I'm using a pot that does not have a non-stick coating.  No coating, no worries.  I didn't send the Tyvek stuff sacks.

Now, permit me advert that amongst the laid upwardly I'm showing today, I receive got the "Inferno" option.  The Inferno selection is what transforms a regular cone into an efficient woods burner.  With the Inferno option, woods becomes your "go to" fuel.  Without the Inferno option, you lot tin nonetheless terminate wood, but efficiency together with repose of utilization suffer.  Inside the rolled upwardly cone are the floor, 2 titanium tent stakes, together with the Inferno insert.  Underneath the rolled upwardly cone is a grate.  To i side, is a rolled upwardly wire mesh that is similar to hardware cloth.

Let's receive got everything out of the pot for a petty amend look, shall we?
The components, removed from the pot
Well, let's laid that puppy up!  The cone plant only similar whatsoever other Caldera Cone. Just slide the dovetail articulation together.
The dovetail articulation slides together.
Note the extra titanium reinforcing tab.  Very solid, real good built.
An extra layer of titanium canvas is used as a reinforcement for the dovetail.
With the Inferno option, at that spot is a second, smaller cone that is placed inverted within the main cone.  Like the outer cone, it also is joined past times a dovetail joint.
The inner cone of the Inferno option
The inner cone does non behave weight together with is non reinforced similar the outer cone.

Next, nosotros curl out the floor.  On occur of the flooring nosotros laid the wire mesh, formed into a circle, together with on occur of the mesh, nosotros identify the grate.

The flooring does cost an additional $10.00 USD over together with inwards a higher identify the toll of the Cone together with Inferno option, but I'd actually encourage people to consider purchasing it.  One of the drawbacks to woods fires is that they tin leave of absence terminate scars all over the place.  No i wants to live hiking inwards an expanse pockmarked amongst your terminate scars.  When using wood, I encourage you lot to Leave No Trace.

Now, I'm going to laid the outer cone inwards place.  Notice that the inner cone is left off to the side only for now.  I'm leaving the inner cone out only thus that the diverse components tin live seen easily.  In do of course of written report the inner cone goes within the outer cone.
The floor, wire support, grate, together with outer cone amongst tent stakes.  Note that the inner cone is left out temporarily for photographic purposes.
OK, hopefully the diverse components are clear inwards the inwards a higher identify photo.  Now let's add together the inner cone.  The inner cone is placed upside down within the outer cone.
The Ti-Tri Caldera Cone amongst Inferno Option, all laid upwardly together with ready to go.  Just add together wood.  :)
Note that the tent stakes create non boot the bucket through the oval vent holes inwards the cone.  There are special circular holes specifically for the tent stakes.

OK, let's add together fuel.  Here, your terminate edifice skills are going to come upwardly into play.  Today, I'm going to utilization the "log cabin" terminate lay.  I line off the outer cone for repose of access.
A "log cabin" terminate lay
To start, I identify a lot of easily burned stuff on the real bottom layer, straight on occur of the grate.  I utilization items such as real dry, crinkley leaves together with such as my kickoff layer.  You powerfulness also desire to send artificial tinder for terminate starting purposes.  On occur of my foliage tinder, I add together kindling consisting of the smallest sticks that I tin find.  I together with thus add together successive layers of sticks.  Each additional layer is comprised of sticks of increasing thickness.  Note that I'm stacking them inwards a foursquare pattern.  This foursquare pattern is referred to as a "log cabin" terminate lay.  This type of terminate lay allows for practiced air time period which eases terminate starting together with provides for practiced combustion.

When I've completed my terminate lay, I touching on off the tinder on the real bottom layer.
Starting the burn
Just i "little" work though.  It rained today.  In fact, it was a pretty decent rain.  Everything is wet.  In fact, I deliberately chose to essay the Ti-Tri Caldera Cone on a rainy 24-hour interval because pelting is i of the facts of life of woods fires.  You have to live prepared for it to pelting i time inwards a while.  Do not assume you'll receive got practiced conditions when you're out on the trail!  The terminate only won't start amongst alone my lighter.

How did I handgrip it?  I permit the terminate flaming completely out, together with and thus I added a capful of alcohol.
Re-starting the fire, this fourth dimension amongst alcohol.
As the alcohol burns, it dries the wood.  And inwards a moment...
The terminate takes hold
Success!  The terminate takes hold.

What's that?  This is a flake contrived?

Well, maybe.  I hateful I did deliberately boot the bucket out on a rainy day.  But, guys, this is existent the world stuff. Wood fires are non automatic.  Wood fires are non similar your petty gas stove where you lot only plough the knob, striking the piezo button, together with you're cooking, come upwardly pelting or come upwardly shine.  You're far to a greater extent than at the mercy of Mother Nature.

And inwards illustration it's non obvious, you lot receive got to programme your trip such that you lot tin discovery wood.  I typically similar to line into military camp amongst enough of daylight left if I'm going to live using a woods fire.  Finding woods inwards the black is a violet pain.  You also require to allocate fourth dimension for edifice the terminate lay together with getting the terminate started.  Wood fires are definitely a lot to a greater extent than "fiddle" than using a stove amongst fuel that you've carried amongst you.  Wood fires receive got a lot to a greater extent than time, are a lot to a greater extent than work, together with are far from guaranteed.  Of course, people receive got been using woods fires for centuries, thus there's no argue you lot can't create it too, but pass only about fourth dimension thinking, planning, together with practising.  Remember the v "P's:"  Prior Planning Prevents Poor Performance.  Wood fires are great, but don't come inwards in to it also lightly.  Do you're homework or you lot may live inwards for a cold, moisture nighttime out on the trail.

OK!  Enough lecturing from worry wart Jim.  Let's larn on amongst it.

Now, when you lot seat the pot on, identify the handles away from the cutting out where the handgrip would stick out if you lot were using alcohol or hexamine. Flames are going to come upwardly shooting out of that spot.  It's no identify for a handle!
Flames volition come upwardly out of the handgrip opening.  Position your pot accordingly when using wood!
This is NOT where you lot desire to seat your handles!
Flames exiting out the handgrip opening.
Of course, if the current of air kicks upwardly a little, you lot create larn only about cool flame plumes out the handgrip slot.  :)
A plumage of flame exiting out the opening for the pot handles
That handgrip slot isn't only a origin of neat pyrotechnics; it has a real practical function:  You tin add together woods without removing the pot or interrupting the cooking process.  Sweet!

Now, as a stove, how good does this ensemble work?  It plant great. In fairly brusk order, I had a pot of boiling water.
Water boiling on a Ti-Tri Caldera Cone fueled past times wood
And it's a actually good, potent boil.  Nothing insipid most it.
A vigorous boil on a woods fired Ti-Tri Caldera Cone
OK, thus nosotros tin definitely boil water.  Now, let's receive got a await "under the covers."
A await inwards through the handgrip opening
Take a await at that woods burning.  That is HOT.  The inferno selection lives upwardly to its name, producing a good, hot fire.

OK, let's line the pot off together with receive got only about other look.
The Inferno selection at work
It's pretty slow to run across why they telephone telephone it the Inferno option.  Those sticks are pretty good burned downward past times this phase of things, but there's nonetheless a lot of combustion going on.  And those coals volition release a squeamish consistent heat.

Hmm.  A squeamish consistent heat, eh?  Let's essay something.  Let's seat that pot of boiling H2O dorsum on.
Water NOT boiling over a woods fire.
This photograph is a petty dim, but notice that the H2O is non boiling.  In other words, amongst the Tri-Ti Caldera Cone together with a flake of experience, i tin create to a greater extent than than only boil water.  No, non just the convenience of gas, but i tin vary the rut together with create to a greater extent than than only boil water.

Now, inwards the procedure of cooking together with experimenting amongst this stove, I filled it amongst sticks together with permit it terminate downward 4 times over the course of written report of the eve without emptying the stove.  Well, amongst all that wood, you'd recall I'd receive got a large pile of ash.
Even though I reloaded 4 times, all that was left at the halt was this petty flake of ash
Nope.  Even though I reloaded the stove 4 times, all I had left at the halt was a petty flake of powdery white ash.  Let me stress that:  White ash.  No chunks of charcoal.  Guys, this Inferno selection actually works.  That is actually good, consummate combustion.  And that petty flake of powdery ash is real slow to dispose of.  Just dig a petty truthful cat hole amongst whatever you're using for a potty trowel together with dump the ash in.  Replace the soil, together with you're done.  No terminate scar.  Sweet.

And no difficulty putting out the fire.  I've had woods fires that were a huge, fourth dimension consuming hassle to seat out.  I had to boot the bucket multiple times dorsum to the creek fill upwardly all my H2O carriers together with schlep H2O dorsum upwardly to military camp to seat the darned matter out.  With a Ti-Tri Caldera cone, it'll combust thus completely that it volition terminate itself out.  There's actually no terminate to seat out.  Just mitt banking concern check the ashes to brand certain they're cool, together with you're pretty much done.  The ashes tin live disposed of inwards modest truthful cat hole.

DISCUSSION
OK, thus it's a squeamish stove, but c'mon.  The ultimate ultralight stove system?

Well, why powerfulness I telephone telephone this the ultimate ultralight stove system?  OK, what's by together with large the heaviest share of an ultralight stove laid up?  The fuel.  With the Ti-Tri inwards woods burning mode, at that spot is no fuel to carry.  There is no fuel lighter than no fuel at all.  In woods mode, your fuel weight is zero.  Pretty tough to occur that.

OK, yeah, cypher fuel weight is pretty cool, but aren't at that spot a lot of other woods burners out there?

Indeed at that spot are, but this one, existence titanium, is pretty doggone light.  Not alone is it light, it's compact.  It rolls upwardly together with fits inwards your pot (note that at that spot are unlike types of Caldera Cones out at that spot that shop unlike ways.  Refer to TrailDesigns.com for farther information.)

But those things lonely aren't why I telephone telephone the Ti-Tri Caldera Cone the ultimate ultralight stove system.  The existent fundamental hither is flexibility.  With a lot of woods stoves, you lot pretty much receive got to terminate woods every fourth dimension you lot cook.  Not thus amongst the Ti-Tri Caldera Cone.  The Ti-Tri Caldera Cone runs every bit good on hexamine (e.g. ESBIT) or alcohol as it does on wood.

Consider a recent backpack I went on.  The kickoff night, I camped at 5000ft/1500m.  The 2nd night, I camped at 8000ft/2400m.  The tertiary night, I camped at 10500ft/3200m.  The 4th night, I camped at 11,500ft/3500m.  Wood fires inwards a higher identify 10,000ft/3050m are by together with large illegal inwards the Sierra Nevada where I similar to hike.

Do you lot run across what's going on here?  A stove that only burns woods is no practiced to me.  I need a stove that tin piece of work inwards woods or non-wood manner every bit well.  The Ti-Tri Caldera Cone is that stove.

And await at the advantages.  The kickoff 2 nights, I tin ready amongst wood.  That's one-half the nights of my trip.  I tin pick out one-half the fuel.  What's the weight penalization for bringing the Inferno option?
Item Grams
Wire roll 9
Grate 15
Stakes 14
Floor 18
Inferno 25
Total Wood 81


On whatsoever trip where I tin salve a fuel weight of at to the lowest degree 81g/2.86oz, I come upwardly out ahead past times leaving only about of the fuel at habitation together with bringing the inferno option.

With the inferno option, I tin also adopt a unlike trend of use, i that doesn't require to skimp on fuel.  What would you lot create if you lot receive got a virtually unlimited provide of hot water?  How most a hot shower?  Yes, I'm serious.  OK, it's a flake of a luxury, but you lot rig upwardly your hydration bladder, and...  Well, you lot larn the idea.  I mean, if you've got wood, why boundary your thinking?  This could live pretty sweetness later a calendar week on the trail.  :)

That together with there's something to live said for the satisfaction of working amongst a woods fire.  A gas stove?  Well, it's almost also easy.  With wood, you lot actually experience similar you've earned it.  And there's only something primordially satisfying most cooking on a woods fire.

Is a woods stove for everyone?  Certainly not.  If you're planning on long days on the trail where you're getting upwardly before kickoff calorie-free together with stopping to military camp at terminal light, together with thus perchance woods isn't for you.

But on those trips where you lot require to receive got a mix of fuels together with you lot receive got fourth dimension to ready together with utilization a woods fire, the Ti-Tri Caldera Cone is the ultimate ultralight stove system.

Special thank you lot to Randy from Colorado who made his Ti-Tri Caldera Cone available for my evaluation.
