Hi Duong. If you make a mold for casting copper you need to do 2 holes in that mold instead of one. First is for pouring melted copper and the second hole is for making an air outlet. If you will not make a 2nd hole then whole copper will be splatter out of the mold due to the air displacement from the center of the mold. Moreover your material will be more pourus due to the air trapped inside of it.
@@PrimitiveSkillsnet seus porcos adoeceram depois que você infestou o xhiqueiro de cal. Sei que uns foram antes, mas os últimos foi depois. Cal é veneno, corroe o estômago dos bichos. Não sei quem falou que se deve jogar cal onde tem animais vivos. Você pode jogar uns 2 meses antes de por algum animal. Pesquise, não faça o que todos fazem. Todos os canais que jogaram cal nos chiqueiros com porcos sadios, morreram todos. Nossa, fico muito triste de ver como vocês lidam com isto. Tem tanto espaço, leve os porcos para um outro lugar, jogue o cal e depois de uns 45 dias volte com os bichinhos. Eles lambem o cal e acaba com o estômago deles, por isso param de comer e morrem.
@@PrimitiveSkillsnetalso, if you make the pour hole higher than the air hole it will push the air out more easily and you will be less likely to get big bubbles of trapped air. You can do this easily by getting a short piece of bamboo packed with sand and then making a hole through it and placing it on top of the mould. You can also scoop some of the sand out to make it more like a funnel.
Try heating your mold before you pour copper into it, this'll help to dry the sand out and reduce the risk of the mold failing due to expansion of heat that is trapped in the sand. Once the mold is heated, test it by dripping some water on the top outer edge, if the water turns to steam immediately you should be okay to pour the copper in. The finer your sand is, the smoother the final product will be. Great job
LOVE the copper bowl you made! Please keep mining for copper and make many more copper things!!! Did you know that humans have been making things from copper for a long time? Humans were making things from copper and later discovered Iron. Copper tools are older than iron tools!
You succeeded in making a bowl of copper. Very few people can claim the same success. I would like to see a hammered copper bowl. Usually the molten metal is poured into a plate form and then hammered into the bowl shape. I just happen to like the hammered look. 👋👍👍👍👍👍
{Language FRENCH / FRANÇAIS} Bonjour DUONG, voilà, 2024, Je suis toujours là avec ma famille à vous suivre depuis la SUISSE (au centre du continent Europe) nous vous aimons beaucoup, vraiment vous êtes un vrai homme bon et nous vous souhaitons UNE BONNE ANNÉE à vous et toute votre famille. MERCI pour tout ce que vous nous partagez. On vous admire énormément. On vous aime
@@PrimitiveSkillsnet thank you! i watched your " upgrading iron video when it first came out, and it made me start blacksmithing. now i have a little blacksmithing business.
Mức độ nỗ lực của con người để tạo ra bất cứ thứ gì đều được phản ánh qua giá trị của nó. Điều đó khiến chiếc bát của bạn có giá trị hơn những chiếc bát nhẵn bóng ngoài chợ. Xin chúc mừng! 👍👍👍 The amount of effort by a human to create anything is reflected in its value. That makes your bowl more valuable than the smooth and shiny bowl at the market. Bravo! 👍👍👍
The reason the mold failed is because of the water in the earth you used to make the mold. The moment the molten copper hit's the water in turns to steam and it blows up. I think you'd be better off using sand and perhaps some kind of oil to hold the sand together. I love what you do. It's fascinating to be able to observe the whole process! Thanks again.
Try mixing some clay in with the dirt, just enough so that it will hold together. I have poured molds using green sand Which is dirt and green clay mixed together with the right amount of water. And I have made molds using an oil Sand mix. The oil sand mix works best if you can get it, however, be careful opening the mold right away as the oil will flash burn on you.
Duong! Hurray! Your smelting is fantastic! This did not disappoint. Thank you for trying this new skill and for letting us watch. Now you need to make a lathe to turn wood to make bowls and to grind and sand these copper dishes you are making. Well done, Duong!
Judging from what i saw at 31:33, the material you used for the mold may have been wet. Whenever any molten material, lava or molten metal, comes into contact with water, the result is always the same. The molten material causes any water, however little, to flash to steam which is why i believe your molten metal started fountaining like that. It generally helps to make sure the material is dry and to pre-heat your molds before pouring metal inside.
Very impressive! going from native copper and ore to a finished cast product is no easy feat. make sure your molds are dry, as water in a mold will instantly turn to steam and explode, like what happened to the first attempt. also, as others have said, the second hole as in the successful casting is very important as it lets the trapped air escape
I think that this is called "teaching by deliberate failure"... Both the use of wet soil and no air-hole. More teachers should use this method. Tôi cho rằng đây gọi là “dạy học bằng cố ý thất bại”… Vừa dùng đất ướt, vừa không có lỗ thông hơi. Nhiều giáo viên nên sử dụng phương pháp này.
Доброго дня тебе и твоей семье😊 Класная чаша получилась👍 хороший опыт. Надеюсь еще будет плавка меди. Сочуствую утрате поросят осень печально когда животные болеют😔
Ты большой молодец! Спасибо за видео. Можно попросить больше видео про рыбу и пруд? Здоровья и благополучия твоей семье и твоей замечательной великой стране
Я действительно не перестаю удивляться и восхищаться тобой друг, ты проделал такой путь ко всему, чего ты достиг, ты просто молодец! Я хочу пожелать тебе большого здоровья и Божьего благословления 🕊️ Успехов в твоем деле, спасибо за видеоматериал. 👍
I think if you add a little quicklime to the copper before removing from furnace it helps clean the copper and helps it cast a little better. I'm pretty sure it can be used as a flux in this way. Great video as always and congratulations on your first casting!
Sand mound was too wet. You want sand not dirt. Add a small amount of saw dust and clay and very little water. You want just enough clay to coat every grain of sand. The sawdust will absorb the water and the result overnight is tempered casting sand. Also. Spruce funnel, gates and risers ( to feed metal to all parts of mound and to free the air ahead of oncoming molten metal). 👍👏
попробуй изготовить наждачную бумагу из мелкого(можно просеять через кусок кожи с маленькими отверстиями) сухого песка, клея (если в воду не использовать, то подойдет клей приготовленный из вываренных шкур и костей) и нанести все это(поочередно: кожа, затем толстый слой клея, дать ему отстоятся 15-20 минут, сверху нанести отсеянный песок, через 20 минут хорошо прижать и дать сутки в теплом сухом месте на высыхание) на лоскут кожи . Этим удобно полировать литые изделия. (ах да, рыночные изделия изготавливают другим способом)) Наблюдая вашу работу я отдыхаю душой от большого города, спасибо вам!
I think you have done an excellent job sir! Well done! An experience i hope to try myself one day. I do wish that our society here in the US enabled more freedom to live the way you live. Unfortunately, there are burdensome codes and mandates that keep us from being as free as we think we are. I greatly appreciate your work and your content here, please keep up the amazing work my friend! Congratulations 👏👏👏

It does not matter that it is not like the ones in the market. What is amazing is that you made it yourself. Brilliant!!!!
It's great to see how tools, bowls and dishes were made before the industrial age. Glass would be a great experiment also.

Thank you
Explosion is from water in the sand. Dry the sand first to stop explosion
You are a very hard working person.
Things have really taken off ever since Duong got a new t-shirt! 🙂
Why do so much hard work for the workers?
Love the casting episodes
Thats awesome 👌 👏
Try mixing the fine sand with tree resin to make it hold shape better
Amazing work!
😂😂😂😂 copper melts a one thousand degrees fahrenheit then u drop it into ice cold water!! 😂😂😂 You can really move fast! Beautiful bowl!🐔🐓🐔🐓
