- Shells have been burnt for millennia to produce quicklime and lime mortar. Burning shells and limestone is tiresome but the results make it all worthwhile.Lime mortar
This was an amazing video.
My hat is lifted to you Sir!
That's amazing! I was bored watching the first 80% of the video but I was mind blown by the applications at the end!! So exciting!
I’m glad you made it to the end! Hopefully, my videos are getting a little less boring as I figure out how to present these things.
Thank you for this video and this sharing of knowledge. I had already experimented with making quicklime with shells, during a barbecue with friends, after reading old books on lime and I was looking for video examples in order to share with others when I talk about that.
On the other hand, the way you extinguish quicklime, producing only calcium hydroxide, should only be intended for light works, such as paints or the last layers of coatings.
For lime intended for construction, it is necessary to mix it hot with only a very small quantity of water.
You can proceed with a slatted basket, by briefly soaking the quicklime in water, until it stops boiling, then it will reduce to powder by itself. It must be used quickly after preparation and protected from humidity in the meantime.
At your disposal to discuss all this with you in more detail, and share with you the very good old books that I have had the opportunity to read, if you wish.
interesting - which books do you recommend?
is that the ancient Roman hot lime method?
I've been watching several videos about this process. The question that comes to mind for me is...What about the ash mixed in with the burned shells? Does it affect the quality of the lime? Is it better to separate the shells from the ash as much as possible before hydrating?
A few things: it’s best to burn full sized oyster shells or limestone in sizes larger than two or three inches. Getting the ash out is absolutely essential, especially for plaster work. I was burning shells that were broken into very small pieces, making the separation of the ash very tedious. I ended up running it through a window screen. Then, I slaked it by a couple of quick immersions in water which took out most of the remaining ash. It’s doing well for plaster now but the first few tries were kind of hit or miss.
@@HiraethRestorations Thank you. That is useful information.
@@AmblingAloof No problem. Actually, in my recent log cabin restoration video, I had to tackle the ash problem. The lime mortar I used is still going strong after two pretty bad winters and seemingly endless rain.
Mix it with "hemp hurd" to make "Hempcrete" 😉
Wow how awesome thanks for making and sharing the video.
My pleasure!
Awesome man. I know that was a bit of work since i just started smoking meat and I am shit at fire management. Not to mention all the labor you had to do. Very cool. Is there any other material that can be gotten easier than shells? Also could this be used like drywall putty?
I was surprised how tough it was to get shells. The Delaware Bay on one side and the Chesapeake on the other and couldn’t find anything better than crushed shells. That made it tough. Whole shells would have been much easier and cleaner to burn. Limestone is the more common source of lime, especially further from the water. I’ll probably go with limestone from Pennsylvania once I’m out of shells. Easy to get from a quarry about half an hour from here. I’ve never used lime putty like gypsum putty(drywall compound). My guess is lime wouldn’t work too well since it shrinks and cracks when it’s not mixed with sand or clay. Lime putty does have a texture similar to drywall compound after it’s set long enough. That’s when it’s at its best really.
@@HiraethRestorations Thanks for the explanation. You do some fascinating stuff on your TH-cam channel.
I think the shell dosnot cook well prepare more air entrance or a air blower.but awsome video thanks.
The only two ways to get lime is from limestone or sea shells?
