Primitive Technology: Fired Clay Bricks

Primitive Technology: Fired Clay Bricks


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

    All jest aside, your the man bro. Ngā mihi nui ki a koe mō to whakamaramatanga ki a mātou katoa i ngā wā katoa. Ōu akonga he taonga, ka tuku iho au ki aku tamariki ēnei.
    Thank you hugely for enlightening us all, all the time. Your teachings are a treasure that I will pass down to my children.

  2. что-то мне подсказывает, что у него кирпич качественнее, чем на нашем кирпичзаводе

  3. Using ideas and techniques from this series combined with the Fallout 4 engine a respectable primitive man, gather, hunt, build, grow, invent, trade game could be created. Bows and arrows, blowpipes, spears, knives, axes to deal with the wildlife including unwelcome two legged variety found all over (raiders) It's all here. Work huts of various types, grinding stones, water wheel, ovens, kilns …. accomodation huts ….. got it all …. just no guns.

  4. Nice He made 4 good bricks!…. Just another 9.999.999.999.996 to make the Babylonian Wall and the famous hanging garden!

  5. God, look how absolutely strong his arms are. Can we go back to this? Please? I don't wanna live in a house, I'm down to fuck off from society and join him

  6. Bricks, the building blocks to just about anything. You have all three elements to make a lasting home now, bricks, cement ,tiles and woodwork. Would take you
    Months to finish it alone though.

  7. кЛЕЙМА НА КИРПИЧАХ НЕ ХВАТАЕТ))) Пусть потом историки ищут кто их сдеал)))

  8. You should look out if there's any copper rocks to smelt and make into tools , would help a lot as you continue to build up your things

  9. People don’t realize that’s a lot of work collecting the natural clay and at that amount would have been a full days work
