Making clay and grog crucibles for melting metal 

It's not overdone, it's quality-assured and thorough!

This is great! My pottery skills aren't great but I can mek a pot to boil water. This technique will save me doing the sausage coiling carry on. Thanks! I can't wait to try it and boil a brew in it!

BRAVO Jimmy, the best on RU-vid

Thenk you for sharing your knowledge!

I like the way you made that mix one thing my boyfriend is trying to make a crucible that can withstand the Heat enough to melt copper with and brass and all those higher temperature Metals than aluminum and he ran across this video and he said he learned a good mix from you and also that he needs to keep his drink way further away then you have your cup of coffee in the video LOL he said whenever you started ramming it in you would more than likely have half a cup clay grogg in the bottom of the cup he doesn't have a mold like you do but he plans on making one soon because that makes it a lot simpler to turn out a few crucibles like that liked the video

nice work dood! i have one in the oven as we speak, trying to make them for and induction furnace melting iron. i used a cast 2 part ali mold for the outside and a nylon plug for the core. i found your channel hlaf way through my build but would maybe have copied you if i had seen it a day earlier. big up the home melters!

he goes so long without drinking his coffee...absolutely amazing!

This info is useful. Thanks!

This video really made me appreciate the other guy that I watched do this on RU-vid it only took him 10 seconds to form a Crucible in a mold if you haven't seen the video just imagine building the template in a completely opposite fashion to this one

Very cool!

Very interesting! Will be my next job to cast cylinders for my Gold Star....

Of all the uses for Vaseline, this is my second favorite.

Jimmy Jimmy Jimmy oh mate I got to know how does the tea taste with the grog? I am just kidding mate. You’re doing a hell of job! I love the crucibles! I am going to give it a go! Thanks for posting! If you weren’t so far in England I am sure you would be a great mate to lift a pint or two.

Good job, absolutely amazing. I love mold pattern & will like to try my hands on it. I have successfully made crucible to melt brass fired two to three times with great success, I used natural modeling clay with pulverized charcoal.

Thanks man, helpful!

2:15 The reason for the grog is to reduce shrinkage and cracking. Grog particles are larger and already fired, so they don’t contract when fired again.

thank you Jimmy :)

It’s been awhile.. have you glazed any yet. Is there a vid . Love to see that . Great work.

That was a very cold cup of tea ☕️

Just wondering if the box were hinged would it be easier to pack the mixture more tightly with the lid open? At least to the point where you cap it off.

How many degrees of Celsius does it heat and what metals is suitable for melting?

same question from outhers, I think use this to make my frunance fire wall (hot face) U think these can work well for these purpose ?

The glaze is borax , relatively inexpensive and can be applied after the first furnace treatment, then it can be brought back up to temp around 1000 degrees celsius for the glaze to melt ..thanks for sharing this method, i learned something

You can put locator dowls in the box to instead of keep screwing it down each time. Once it's screwed up turn it over drill 2 or 1 hole down each side and glue a dowl in the bottom bit. Then make the mixture a little more watery and pour in the top. Take longer to set and dry but none of that ramming with a stick.

Thank you for the video. What is the difference between grog and fire clay?

'Graphite pencil as composit will it work to make graphite crucible mold

Mr. Jimmy , has the cog mixture been holding up very good for steel melting ? Any crack yet ? How many burn time you average with this mixture of crucible before replacing it ?

Nice video! Very informative! I have a couple of questions. 1. How long do you wait for them to dry before the first firing? 2. How long do you heat them at 250 celcius?

I used to belong to a forum on this subject and the reading became long and complicated. Now you say these will last up to 5 uses for bronze Wow. That is good to hear. Do you think anything more could be added to give them a longer life? graphite perhaps.

Just a suggestion but you know the part where you firmed up the top rim.....just a thought but why dont you put the clay in from that side initially then put the peghole plate on and flip it to do your final pack from the bottom side and to make sure it comes out even????? Again just a thought might save some time.

Hello :) Thanks for your video,he is very instructive ♥ I have a question, what would happen if you went into that mixture, for example, added 1kg coal dust powder + 1kg grog + 1kg fire clay and mix with water ? Best regards from Serbia ♥

How many degrees celcius can this crucible withstand?

OK, just built one. Hope it works....

Can I know the second article what is a heater and thank you 🌹

:) 4:05 I'll name that tune in three Bob.

Can I use a regular concrete mix. I need to withstand max temps to melt steel

So a crucable made like this would be fine for copper,brass, aluminum, silver, gold and small amounts of iron? As for fire brick..that's just common red brick..yes?

Hi sir.. Where's can i get the fire clay?

What temperature Can it resist?

when making these crucibles is it okay to have sugar in your coffee?

Hi, excuse me i don't understand you mix 50% fire clay and the other product is ? Thank you

Sir what's the recipe for the mold itself not the crucible?

Where can I buy fireClay? I can't find it anywhere. Could you pls leave a link so I can reproduce this crucible

Sir i have made a forge last days and now i'm trying to protect air pipe from high temp, but i dont have fire clay, can i do it with 1 part grog, 1 part cement, 1 part hydrated lime and 3 part sand that is recept i found online, i now cement is not suitible for fire what do you think about that recept

So how did it turn out? Did it do okay to melt aluminum? How many cast have you had with it? And what fire lay did you use? I was thinking about making my Hot face of my furnace this way.

NICE JOB, would a handfull of chopped glass fibre in the dry mix add to the strength of the finished crucible I wonder? would appreciate your thoughts.

What material do you mix with graphite to make it wet?

I wonder if he over does do doo too

What is the time in the oven and what it the time on firing and at what Temp. Please.

you should've played "unchained melody" in the background

If possible, the recipe makes the crucible, thank you, brother

Can you do a video showing what shape the crucibles are in now?

hey do you think you can recycle old crucible material to make grog?

What oil do you mix with graphite?

What is grog ?

How do you crush the fire bricks to sand size?

Why not loosen the inner form and let it sit That would let it cure more slowly and you wouldn't get deformation when you removed it from the mold.

When you purchased the grog on ebay, what did you type in to search for, I can't seem to find any. Thanks

Hi,, what temp and duration for firing please??

Would bentonite clay work?

That garage looks familar! Is that coffee or tea?

can you use these crucibles for melting at 2500F for iron?

Apakah anda punya channel youtube yg lain? Tentang teknik

Hey not let it harden in the mold?

4:00 Wondering if some of that mixture fell into the cup a tea 🍵 🤔....

Water use percentage

Bahan bahan yg di perlukan apa saja? Trimakasih

can i use cement instead of fire clay?

can't find firebrick in my area, can i substitute it?

can i order this crucible from u?im from Malaysia..

Che materiale hai usato? Sabbia? Cemento? 🤔

Hi what grog

What is crog

can you please give and other word fro grog ? I wasnt able to get it translated to my language .

sir...can i know where can i get grog..

Why not cut the sound during ff and narrate more details on your great instructions. Best so far it is.

I seen a big chunk of clay fly into your beverage 😆

Fire clay

what is grog.

i took a shortcut and taped a portable massager to a stick 3:17

whats grog

Better to over do than to do over

WHAT THE HELL IS GROGG I GREW UP KNOWING AS SOMETHING TO DRINK LIKE A BOTTLE OF GROGG

what a grog?

No offense my guy but this looks like the slowest way possible lol i geel yhe quality would be like a value cast piston to where clay spun on a wheel would be a forged.

I thought grog was an alcoholic beverage.

Good now teach us, how to make "fire clay"

you have no experience or experience in the foundry

Deal with the fast forward music it's costing u views
