About This Video:
I made some fired clay bricks as an experiment to see if I could make a permanent, waterproof, building material. A brick mold was fashioned from clay and then fired in existing kiln. This was then used to make bricks formed from clay from the creek bank. These bricks were then stored in the hut I built last episode to dry. Using half the hut I could fit 40 bricks. These, when semi dry, were then stacked around the fire to dry out. A small kiln was then assembled from un-fired bricks and used to fire 4 bricks as an experiment. It was about 50 cm tall and 25 cm square in cross section. The fired clay bricks were water resistant, they didn"t dissolve when submerged in water.
I will use these bricks to make a larger kiln and hopefully larger huts later on. I estimate that a kiln with a 50 cm cube ware chamber could hold 40 bricks without being so cramped the flames can"t get through. The good thing about using bricks to make kilns is that they can be constructed quickly without waiting for the layers to dry, they only crack along the joints between bricks while remaining structurally stable, they can be disassembled and built elsewhere or they can be reconfigured/enlarged to make different types of kilns. Repairs are also possible too.
About Primitive Technology:
Primitive technology is a hobby where you build things in the wild completely from scratch using no modern tools or materials. These are the strict rules: If you want a fire, use a fire stick - An axe, pick up a stone and shape it - A hut, build one from trees, mud, rocks etc. The challenge is seeing how far you can go without utilizing modern technology. I do not live in the wild, but enjoy building shelter, tools, and more, only utilizing natural materials. To find specific videos, visit my playlist tab for building videos focused on pyrotechnology, shelter, weapons, food & agriculture, tools & machines, and weaving & fiber.

Digging clay for brick mold Crushing old pottery for grog Mixing grog into clay Forming the brick mold, adding a tab for lifting It's 25 cm by 12.5 cm 25 cm x 12.5 cm x 6.25 cm Into the kiln Fire a large pot at the same time (so as not to waste fire wood) Cover with old pottery.
Fire sticks The pottery itself must glow incandescent red or hotter to be properly fired Fired mold ready to make bricks Digging a clay pit Clay from the creek bank Into the pit Water Treading clay Picking out stones.
Forming bricks Sprinkling wood ash down to stop the bricks sticking to the ground Tip: soak mold in water/wood ash solution so the clay slides out of the mold easily It rained a lot during this project, the hut was essential in keeping the bricks dry Staking bricks around fire to dry further Cutting some bricks with a bark string to form half bricks Drying bricks out with help of forge blower Turning bricks so they dry faster Stacking next lot around the fire.
This is only to dry them out. Firing them properly will come later Bricks visibly drying Mining More clay (stop motion for dramatic effect) Collecting standing dead wood Breaking up fire wood Assembling small brick kiln for firing experiment Kiln is 50 cm tall and inside is a 25 cm square cross section Note the brick ledges, this is what the bricks to be fired will sit on (instead of a grate).
Only 4 bricks will be fired, I tried 6 but it didn't let the flames pass through enough. Always ensure at least a fingers width between bricks. Flames moving between bricks nicely At about 30 minutes I added bricks to the top to help keep the heat in while still letting the draft flow through Too much wood chokes kiln of air, cooling it. To little, and the kiln cools down due to lack of fuel. Just watch the flame and the pottery glowing and adjust as necessary. Adding more bricks to keep the heat in while allowing a gap for the flames to come through Clay must glow incandescent red or hotter, otherwise it will dissolve in water afterwards. Closing up kiln. Total firing time: 2 hours Opening the next day when cool 4 Fired bricks.
Submerging brick for water test 15 minutes under water Brick passes water test intact. An un-fired brick would have dissolved in water Mold and fired brick

but how will clay bricks receive a job now?
10:15 most random soar ever lol i mean became as soon as it even necessery?
Mining extra clay at 5:Fifty three, 5 exp plunge
No swimming pools = no complaints
i'm factual gonna aid looking at this on auto play
Thanks
Truly, no longer the entire lot he does is inclined. As a minimum, he’s got a digicam with him.
