IMPROVED Tabletop Perlite Hibachi Version #3

So heres my current (maybe final but who knows!) version of the tabletop hibachi made from lightweight perlite concrete.
Ratio
3 parts Perlite
1 part White Portland cement

Made this grill. Turned out great. I drilled holes in the side for more air to circulate through. Amazing!! Wish I could leave a photo

Great to hear other having success

[@realazduffman]

How much perlite did you use? How many quarts/pounds?

[@Garanon5]

I'm glad this popped up on my feed. Authentic Konro grills are very pricey and after googling DIY options I was surprised how expensive fire bricks are. The cheapest I found were about $8 USD apiece, 24-26 of them can add up, defeating the purpose. Thanks for sharing.

On the inter form, taper it --smaller at the bottom than the top-- as soon as you start to lift it out the seal is broken and it should lift out. Excellent work Many thanks and may you ad yours be safe

[@davidcowcill3102]

Great piece of kit to have! Nice work

[@foodrelated]

Thanks

[@dalegrover7633]

A suggestion for using cardboard, you could use a form inside the cardboard to keep the shape & then pull that out easily once it's gone hard & then burn off the cardboard.

[@foodrelated]

Interesting idea, thanks.

[@FASIGMAN]

Well done friend ignore A wholes.............Thank you.

👍

Great video. I was searching for a perlite/cement recipe because I'm going to make a portable launchpad for my 3D model rockets that I am launching. This should give me a lightweight portable launcher that will hold up to the rocket exhaust. I'll make a video regarding the fabrication and use to post on my channel in a couple of weeks.

Cool thing is that technique is cleaner and easier than clay and there is a few projects I can think of that makes more sense to use it for. Well done mate.

[@foodrelated]

Thanks!

@@foodrelated I have some Appropriate Technology books as PDFs that have a lot of low technology stoves and stuff that would make great projects for you. I’ll look them up or you could Google appropriate technology and find a ton of stuff to do.

[@TheEdrichard]

Nicely done! Would be cool to see kebabs with a mixture of meats and veggies being cooked on it.

[@beralmeida]

Looks very nice!! Grape tomatoes wrapped in bacon are really tasty on the hibachi. Maybe you should try!

[@foodrelated]

Sounds very good!

[@dalegrover7633]

I had forgotten that you were like me, another Pom residing here in NZ, your Canterbury jersey should have given it away 😊

Does the size of the perlite grains matter? I found perlite grains with of 0-1,5mm. I am hoping to get a smoother looking result. Do you think it will insulate less as there might be less air trapped inside?

[@harrietthoppe7501]

Hi great Video once again. Have you thought to try the mix with Water Glass maybe, instead of plain water.

[@foodrelated]

Thanks for watching. No I didn’t but if I do end up making another I may well experiment with it.

[@mundanestuff]

Jalapenos, either wrapped in bacon or not, stuffed with meat and cheese are amazing on a hibachi. I really like to roast any pepper at all on one, hatch chilies, Anaheim, poblanos, even regular old bell peppers are good on it. Of course steak, chicken and other meat is the default for these grills, isn't it?

[@foodrelated]

A whole heap of ideas there! Thanks.

[@realazduffman]

To anyone who has made one of these:
1. Does regular cement hold up to the heat or do you need to get a special cement?
2. Could you add sand or anything else to get a smooth surface?

[@raymondparker184]

Portland (regular) cement will last for a while, but will eventually crack due to temperature expansion/contraction. A better alternative is to use a refractory cement. Yes, you can add sand, and also wood or charcoal ash. Sand fills voids and gives an overall smoother finish, and the ash gives increased strength. Almost all construction concrete has fly ash (byproduct from coal-fired power plants) mixed in for this very reason. Enjoy your build !

[@user-zx2qu9sn2z]

I tried it but I used refractory mortar with the same 3 to 1 ratio but it did not give a good result, it cracked and it was generally crumbly. I think it's due to the sand in the mortar. I'll try again with only cement :)

[@l0I0I0I0]

Let us know how it worked for you, not using sand? Is the refractory cement safe for food?

[@user-zx2qu9sn2z]

@@l0I0I0I0 well I remade it with normal cement and Perlite, and it worked perfecty :) Refractory cement should not be an issue as the food will not touch the cement itself. I use a metallic grid to cook the food

[@saren6538]

Could you use a hydraulic lime instead of cement ?

[@foodrelated]

Maybe

[@Yahatacooky]

What are the dimensions of the hibachi?

[@foodrelated]

Approx
45-50cm long
20cm wide
20-25cm deep

[@brandonscoffield9974]

No draft holes?

[@foodrelated]

After having used it a few times I’m not sure it’s needed…
