I mixed sodium silicate (waterglass)

I don't know, maybe it sparks when hotter. It did spark when I made a cast iron hammer: kzfaq.infoqxc-nwnDdgg?si=6IMYoafuXsLIdHWb

I have never used PolyCast. All I can say is that natural/translucid PLA burns out great.

Thank You!

Cheers!

I doubt that it has anything to do with toyota supra mk4 😂 It's just a version or sequence of the printer. I used to have Prusa mk2 before that.

Cheers!

But in my unprofessional opinion it should be able to re bake. I’m not crafty so idk if it would fix the issue. Hopefully the op responds

Iron is way too hot and reacts with plaster, so not only will it not work, but it's also super dangerous to attempt casting iron in a plaster mold. I do like to challenge theories and sometimes try things myself even though the internet says you should never do it 😂 Once, I tried to cast something from iron in a plaster mold. It's good that it was a small quantity of metal. I witnessed a volcanic eruption effect. The plaster could not take the temperature, and part of it just melted or crumbled. You could also smell that there was some kind of chemical reaction going on. It reminded me of an illumination rocket (not sure if that's what it's called)-one that you light up and hold in hand to signal your location. The metal was also splattering like a volcano - dangerous. Melting metal inside a mold is tricky. There are a few things to watch out for. *Loss of detail* When a crucible is used with high melting point metals, it will not look the same after melting them. The crucible will deform a little bit and "calcify"-calcify is not the right word, but I can't think of any other way to describe it. From the high heat, the crucible will become "glassy" and will not look the same. If the same thing happens with a mold, the cast will not come out great. There will be a loss of detail. It can be done with lower melting point metals, but you really need to watch the amount of sodium silicate added to the mold. You should use very little waterglass. Anyway...there is a video about silicon carbide mold making on the way. Cheers!

@@ShakeTheFuture Looking forward to the next video! Here's my attempt from today: kzfaq.info/get/bejne/oq2glapontC5iX0.htmlsi=SPDRdVFy5k_oWSVg Added too much sodium silicate, got the bubbles. Have you considered adding alumina and silica into your SiC/Waterglass mix? 70% alumina + 30% silica is the ideal ratio for increasing the chance of forming Mullite, which can significantly improve the strength of the SiC matrix. Mullite forms as needles. My formula is based on yours, but instead of 90% SiC 10% waterglass, I do 40% SiC 10% Waterglass, 50% Mullite mix. However, I like your recipe for its simplicity of only two ingredients.

@@toxomanrod Interesting. Thanks for sharing. I might try it out..never knew what's Mullite 😊

Awesome! You're in for a treat, because that's exactly what's coming. Copper&Cast Iron videos. Cheers!

Hi! I don't know the temperature since there is no way for me to measure it. All I can say is that it works. I don't know all the theory behind why or whether or not it should work, but it does. I can also melt small quantities of stainless steel, but only very small amounts. Cheers! Denny

Do you mean cutting the pipe? If so, then I cut it using an ordinary pipe cutter. Similar o this one: amzn.to/3KjRRCZ

Thank You!

Yes, Indeed 😊

Ok 😢......👜✈

At least I did not break the spaghetti before cooking 😂

Cheers!

@@ShakeTheFuture cheers to you

If you live in EU, I get it in 25kg bags from here: ots-store.com

The spaghetti would defrost and deform before I had a chance to make a mold. Cheese wax held it all together.

Thank You!

Welcome to the community! Cheers!

Probably the secret is in the bonding process.

@@paulcohen1555 Hi , thank you for making conversation. i was glowing my crucible like in the description. and it was really red. when the crucibile is cold, everyhing apprears perfect, but then heating up, it gets as soft as butter. Touching the cruble with my grill tongs does not improve the situation. today I received F12 grit SiC. Trying to mix in as much as possible into the paste to make it more sturdy even with hot temperatures.

I use medium or fine grit. I don't think the problem is the grit. I don't know how did you make it, but I would try the "glass method" crucible. If it still breaks easily, I would try adjusting sodium silicate used...Increase the quantity added to the sic. Cheers!

Challenge accepted!

Yes, that's what I also did 😀

@@ShakeTheFuture sorry it is the standard Italian answer, but really cool video, hope you have a working fridge going into warmer weeks

Thanks Carlos!

Thanks! Yes, it's definitely NileRed's style of content. Cheers!

Not my fault this time 😀 The fridge was leaking gas and it stopped working.....I also leak gas, but I still operate 😁

Thanks!

@@ShakeTheFuture you are welcome

Jā...kaut kas uz to pusi ir.

Yeah, they did seem to be stronger or maybe It was just my imagination.

Too many youtubes only show what works and the experimental vids are a nice change of pace. More please!
