Ahhhh... Using a hand-drill to start a fire. Now that takes me back to my days at the Wilderness School! I'd love to try and make a pottery-kiln (I'll be researching that soon...)

#Australia - Making #lime with Primitive Technology

"When heated above 840 degrees Celsius, the lime decomposes into calcium oxide (CaO) or #Quicklime and releases carbon dioxide (CO2). When water is added to the quicklime it becomes calcium hydroxide Ca (OH)2 or #LimePutty. From here the calcium hydroxide can then be shaped into a form and allowed to set.

Carbon dioxide enters the lime putty as it dries causing it to turn back into calcium carbonate. The new calcium carbonate has then set, remaining solid and water resistant.

In my local geography, calcareous rocks such as limestone are absent leading to a difficulty in acquiring the feed stock for lime making. However, I was still able to make lime by collecting the shells of large terrestrial snails that are native to the rainforest here. The unoccupied shells of these snails were gathered up and stored at the hut. Fire wood was gathered and packed neatly into the kiln.

Importantly, the firewood was stacked on top of the grate rather than underneath it in the firebox as is the normal procedure for firing pottery. Using an ordinary updraft pottery kiln in this configuration allows it to reach much higher temperatures than would be possible during normal use. The wood was lit from above and the fire burned down towards the grate. Alternate layers of shells and wood were added on to this burning fuel bed. After adding the last layer of wood to act as a 'lid' to prevent heat loss from above I left the kiln to finish on its own, unsupervised. The whole process took about an hour and a half.

When the kiln had cooled down a few hours later, I took out the calcined shells. Not shown in the video was the fact that some shells got so hot, the dirt stuck to them turned into slag and fused to them, possibly with the lime acting a flux lowering its melting point. This extreme heat (+1200 c) should be avoided as the over burnt lime becomes 'dead lime', unable to slake in water. Most shells were still useable though. They were taken out of the kiln and had water added to them.

An exothermic reaction then ensued. Heat was produced as the lime quicklime turned into slaked lime. The water heated up creating steam and the shells decomposed into a white paste. The paste was stirred and crushed pottery was added to it as an aggregate (sand is normally used for this, I just had a lot of old pot sherds lying about to dispose of).

This lime mortar mixture was then formed into a block shape and left to dry. It took about a week and a half to set as we have had extremely humid, wet weather. The block was observed to have set demonstrating its properties.

What I created is actually lime mortar, typically used for mortaring bricks and tiles together. It’s basically the ‘Glue’ that holds together the building blocks of masonry structures. From my research 20 kg of lime mortar is used on a 1 m square section of brick wall. 5 kg of lime to 15 kg of aggregate (sand, grog etc.) per a 1 m square section of bricks. The shells, though large, are not terribly abundant. A method for finding shells efficiently needs to be made before considering making lime mortar in this fashion. From my experience sand bars in a creek sometimes accumulate snail shells from higher up in the mountains. In these spots, water velocity decreases and shells in the water tend to drop out of the water column. Additionally lime may be partially replaced with ordinary wood ash in mortar without a corresponding decrease in strength. To conclude, making lime in a land without limestone is possible but can be problematic when trying to do so on a large scale."

How to Make #Lime (#Apog) from #Clamshells

Aug 1, 2020

"Eating seashells is one of your favorites?... Well, what you can do to the #clamshells?... Some of us, didn't know on how to make it into valuable product just like making lime or 'apog'. Find out in this video, saving shells to become waste."

The new plaster materials is here, and so is the bill.
172.65 (including VAT and 30% discount). Not so cheap for 2.5 bags plus color pigments. But it's not every day you treat yourself to this luxury.
And if applied properly, it will last for decades... :)
Quality has its price. Good work too.

The photo shows several bags of mortar from Calchera di San Giorgio on a wooden bench next to slippers and sandals. In the background, the wood paneling of an old living room is visible. Some light shines through a partially visible window. Several different stones are on the windowsill. On a second new Swiss stone pine bench, a sweater made of fleece is visible on the left side and a round open sewing box on the right side. Below the bench, there is a small measuring cup on a parquet floor.

Mortar cart attacks.
And fills the cracks.

Since we didn't get around to doing the full foundation job, I'm at least patching the cracks with lime mortar so it doesn't get worse in winter.

Not aiming for a pretty job, just need to finish it today as the weather will soon be too cold. It will get cast into concrete anyways 😱

#Stone #Foundation #Lime #Mortar #Repair #DIY #LogHouse #Homestead

A large builders bucket (not Sir Cracksalot this time) in a self built cart. Inside is a greyish white mortar mixed not too sloppy so it can be smeared deep and not fall off a vertical wall. Some mortar tools are also on the cart. Nearby a cable drum and an electric hand mixer.

A stone foundation on the north side of a log house with yellow planks. The soil is recently disturbed from fixing the grade and the gaps between the stones are filled with fresh grayish white lime mortar. The mortar cart stands on the far corner, now less full.

Improvised mortar cart. Because that big mixing bucket can get pretty heavy and the lime is in the barn, the sand outside the barn and the water over by the well, so it gets hauled around to join them all into some nice mortar. Then carted to where it's needed.

Saved me a lot of lifting today! 👍

#Mortar #Lime #DIY #Renovation #Homestead

An old self-built cart that was formerly used for hauling firewood around. Now it is laden with a large builders mixing tub and some accessories: A spray bottle filled with water, two small yoghurt buckets, a sponge, a rag, a spatula and a putty knife. In the bucket is sand with bright white lime thrown on top, not yet bleended.

Almost every tool and material ready for starting plastering the oven.
Still waiting for SILCATEX-SE glass mesh fabric, which should arrive the next days. Cocciopesto lime mortar with brick dust (0-3mm) and natural pre-spray adhesive mortar (rasante di livellamento) both from Calchèra San Giorgio. Excellent natural products.
Have to work in serveral layers and with two different plaster carriers. (glass mesh fabric and inox mesh 12x12mm).

Some lime mortar building history.

Lime mortar takes a long time to dry and cure. Up to two years for a whole building. During that time it absorbs CO2 and releases moisture. But only if it is warm enough.

It was beneficial to have some residents in a new building who would heat it and ventilate it and breathe out some CO2 (probably not a huge factor, but this was the belief at the time).

But since it was very moist and unpleasant inside during this time, the building was rented for free or very low rent to the poor, to inhabit during drying time. When it was dry enough, they got kicked out and would move to another new building.

The German term for these poor people was "Trockenwohner" (drying residents).
