Primitive Technology

I made iron using the old blower variant but using a larger diameter fan (30 cm rather than 25 cm). I did a longer smelt and a shorter smelt. The long smelt made 10 g of iron but the short smelt made 14 g sugesting that multiple shorter duration smelts may be more effective at producing iron rather than one long smelt. The iron was then put into a knife shaped mold and placed in a forge under a flattened tuyere to spread the blast ino a sheet. The iron in the mold partially welded and fused but didn't completely melt and it was broken in the middle. I put this down to the mold being too far under the tuyere blast as the coals above got white hot. I'm counting this as a partial sucess because the result could still be sharpened into some type of tool. The iron knife I made previously this was melted much more completely in its mold and further exeperimentation would be needed to re-learn this method of insitu casting.

About Primitive Technology:
Building things in the wild completely from scratch no modern tools, no modern materials.
The challenge is simple but strict: If I need a fire, I make a fire stick. If I need an axe, I shape a stone. Every hut is built solely from trees, mud, and rocks. I don't live in the wild, but I love discovering just how far we can go using only natural materials and human effort.

I tested a variant of roof tie where it is a flat trapesoid with curved up sides to test if I could fit more of them into a kiln and have them cover more roof area than the curved barrel tiles.

It turns out that the reason curved roof tiles are so comon is because the shape gives a long tile more strength throughout its length. After making, firring, and laying the tiles, only 2 of 36 survived. The flat tiles were so weak because of the change of design, I was forced to return to the old variant after a month of wasted effort.

I might take a break from filming tile making now and focus on other interesting projects.
