原始技术:烧制粘土砖

Primitive Technology: Fired Clay Bricks

挖做模具的粘土
Digging clay for brick mold
把旧陶器碾碎做成陶渣
Crushing old pottery for grog
把陶渣揉进粘土里
Mixing grog into clay
制作模具 给模具加上把手
Forming the brick mold, adding a tab for lifting
模具长25cm 宽12.5cm
It’s 25 cm by 12.5 cm
模具的最终尺寸是25cm×12.5cm×6.25cm
25 cm x 12.5 cm x 6.25 cm
放进火炉
Into the kiln
为了不浪费木柴 同时烤一个大罐子
Fire a large pot at the same time (so as not to waste fire wood)
用旧陶片盖住
Cover with old pottery
点火
Fire sticks
陶器必须烧到发红 或白炽发光
The pottery itself must glow incandescent red or hotter
才能烧得成
to be properly fired
模具已经可以用来做砖坯了
Fired mold ready to make bricks
挖一个装粘土的坑
Digging a clay pit
在河岸挖粘土
Clay from the creek bank
放入坑里
Into the pit
用脚踩踏 将水和粘土混合到一起
Water Treading clay
捡出石头
Picking out stones
制作砖坯
Forming bricks
往地上撒些草木灰
Sprinkling wood ash down to stop
防止砖坯粘在地上
the bricks sticking to the ground
提示:事先用草木灰水浸泡模具
Tip: soak mold in water/wood ash solution
可以让砖坯很容易从模具里脱出来
so the clay slides out of the mold easily
制作砖坯这段时间里经常下雨
It rained a lot during this project,
没有小屋砖坯肯定干不了
the hut was essential in keeping the bricks dry
把砖坯围着火塘堆起来 进一步烘干
Staking bricks around fire to dry further
用树皮绳把一些砖坯切成两半
Cutting some bricks with a bark string to form half bricks
用鼓风机帮助烘干
Drying bricks out with help of forge blower
把砖坯立起来 这样它们可以快点干
Turning bricks so they dry faster
继续把砖坯垒在火边
Stacking next lot around the fire
这只是为了让砖坯干透
This is only to dry them out.
砖坯干透后才能入窑烧制
Firing them properly will come later
明显看得出 砖坯在变干
Bricks visibly drying
挖更多的粘土
Mining More clay
收集没有倒下的枯木
Collecting standing dead wood
折断柴火
Breaking up fire wood
砌个小砖窑来试验一下
Assembling small brick kiln for firing experiment
它有50cm高
Kiln is 50 cm tall and
内部是一个长宽各25cm的正方形空间
inside is a 25 cm square cross section
注意突出的部分
Note the brick ledges,
要烤的砖坯架在这个地方
this is what the bricks to be fired will sit on
这样就不用装格栅了
(instead of a grate)
一次只烤四块砖
Only 4 bricks will be fired,
我试了放六块砖 但是火焰流通不顺畅
I tried 6 but it didn’t let the flames pass through enough.
砖坯之间至少要留一指宽的距离
Always ensure at least a fingers width between bricks.
火焰顺畅地从砖坯间穿过
Flames moving between bricks nicely
烧了30分钟后 我往上面盖了砖头
At about 30 minutes I added bricks to the top
这样可以保住里面的热量 也能让气流流通
to help keep the heat in while still letting the draft flow through
太多木柴会阻塞空气流通 使炉温降低
Too much wood chokes kiln of air, cooling it.
木柴太少则会因燃料不足导致炉温降低
To little, and the kiln cools down due to lack of fuel.
要根据火焰和砖头发热发光程度
Just watch the flame and the pottery glowing
在必要时调整木柴量
and adjust as necessary.
加上更多的砖头来保持炉温
Adding more bricks to keep the heat in
留一个缺口让火焰通过
while allowing a gap for the flames to come through
砖头必须烧到白炽发光
Clay must glow incandescent red or hotter,
否则它以后沾到水就会溶解
otherwise it will dissolve in water afterwards.
封上火炉 总共烤火时间:2小时
Closing up kiln. Total firing time: 2 hours
第二天冷却时再打开
Opening the next day when cool
四个烤好的砖头
4 Fired bricks
把砖头放入水中检验
Submerging brick for water test
放入水中 等待十五分钟
15 minutes under water
砖头没有溶解 完美地通过了测试
Brick passes water test intact.
没烤过的砖头在水中就会溶解
An un-fired brick would have dissolved in water
模具和烤好的砖头
Mold and fired brick
