Thank you, SendCutSend, for delighting us with your irreverent stickers, and stoking our sweet tooth.

As we've started ordering more 'blanks' to meet demand for our flat-pack kilns, not only are they arriving on a pallet, we've gone from a couple Sour Punch sticks per delivery to a WHOLE BOX of Sour Patch Kids!

One photo shows these pieces mid-production, getting ready to be part of kilns going to 3 different customers.

"Sheet" is most definitely happening.

🎉 It's time for... the party trick!

💦 Come one, come all, see what happens when you take one full pail of water and pour it on another full pail of !

🌿 Seriously though - it's a great illustration of what biochar can do to improve , and yes, you can absolutely make biochar yourself with one of our flat-pack, personal size biochar kilns.

There is still so much slash from the December storm to clean up - and yesterday we provided the kiln for a demonstration for volunteers at the ’s Rake the Twigs event to support the Old North Road Cemetery.

Think we found the most fun way to compact a huge pile of fruit tree prunings into a kiln. 100% would recommend!

A 10X temperature difference from top to bottom - that's what you see with flame cap kilns, and it's one reason they're such a great alternative to pile burns.

Soil gets warm, but not for long, as forms in layers on top to protect it.

Meanwhile, the flame cap burns off the volatiles, and re-burns particulate for low smoke and lower emissions. ❤️❤️❤️

Excited for to put these two kilns to great use teaching and making here in Washington State!

A great way to demonstrate how flame cap kilns with an open bottom will protect the soil beneath it - unlike the burn scars often left by standard open pile burns.

FWIW, there was more cardboard at the end than what is shown in my hand - that was just the first piece I found! 😅

Look Ma, no tools!

Assembling - and disassembling - FlameWise kilns couldn’t be easier. There are no tools, fasteners, or moving parts on these flame-cap kilns.

The six interior panels and six heat shield panels can go together in about 2-3 minutes, or, if you’re explaining all the features like in this video… about 7 minutes.

I tried this technique (of using the heat shields to trap the steam and get more out of each drop) the first time back in April, when we were quenching with a pail and not pressurized water - it worked wonderfully and used way less water. Was reminded of it recently by - time to add it to the standard quenching procedure!
