Satanite is a good name for a fire pot coating. 👍

[@sarlaccstapeworm990]

I JUST bought 2 new forges. One propane (for copper & aluminum), and one smaller electric one (for precious metals)... This is the next step for me before I get started learning how to smelt some metal. This is one of the only videos I've seen on this particular subject. Every other video I've seen is either about building the forge itself out of old propane tanks or something, or strictly just melting the metal, and pouring the bars (or billets). Thank you very much for the educational content! It was a great help!! 👍

[@GaryMcKinnonUFO]

My first furnace arrived today (Vevor 12kg) and didn't come with enough cement so i ordered some Satanite. This was very helpful, thanks, liked and subbed.

[@danharold3087]

I use a flexible plastic bowl to mix the satanite. After application I let the bowl dry and flex it to remove the dried satanite which I collect in another container. Because it has not been fired this leftover material can be ground up and used later.

[@marmachuk16]

Incredible video, very good information and straight to the point. 👍 The one thing I can add is that satanite applies very well with a 3 inch wide paint brush, and the paint brush is very cleanable. The bowl and mixer I used, I disposed of though

[@bendent9002]

As you were in fast mode, it reminded me of being at the TMS race track. Im going to look into the satinite to use also. Great info. Thank you.

[@jasonnewville4816]

Thanks a lot for posting this for everyone, it's exactly what I was looking for!!

[@tobhomott]

Lol, your last 2 videos came out while I've been waiting for the satanite to arrive so I can complete my new furnace build. Good timing!

[@robinson-foundry]

Tobho Mott Awesome! Hope they help.

[@jimfitzgibbon5492]

Thanks for the info. I watch a lot of video,s on This sort of thing before beginning. You exslained

[@gambitdesert8500]

Thank you very much for the video and telling about all of what you know instead of what you think I need to hear is actually what I needed. I listened to others and was thinking I messed up already ps great channel sorry I just found it but I’m catching up quick. hope all is well

[@bridges5659]

Great video, great job. I think if we experiment with a mixture of plaster of paris, clay in powdered form, grout and gypsum skimmer, we might possibly make a very durable inner wall for a forge or furnace. Might not crack due to a tough combination. 👍

[@scor440]

FYI start at the bottom keep it off your arm if you get to close!

[@daz41262010]

nice to see finishing touches on the furnace great video :)

[@WessCastings]

Really love the channel!! I made my own furnace but I am thinking about buying one because mine is charcoal powered! I am definitely subscribing

[@robinson-foundry]

Wes’s Castings Thanks, I started with charcoal and quickly switched to propane. Propane burners are super easy to make. I used the King Of Random design which is fine but their are many options out there. Good luck!

[@WessCastings]

Seth Robinson thanks so much I’ll check it out

[@WessCastings]

Good news!! I got a devil forge! Just wanted to let you know 😂

[@robinson-foundry]

Wes’s Castings Those work fine! Make sure to coat that ceramic fiber with something like satanite though. If you haven’t heard by now airborne particles are a carcinogen. Have fun!

[@WessCastings]

Seth Robinson yes it came with rigidizer and I ordered satanite! Thanks so much for this video couldn’t have done it without you!!

[@wadeburton5488]

Have you tried using a trowel to apply it? Seems like the perfect consistency for it and would give you a nice smooth finish.

[@redshiftcnc]

Thanks for the video:) i just ordered some of that stuff. Very informative👍

[@fpcsdseniors9912]

I'm interested in starting a backyard foundry for smelting copper scrap. What is a good safety resource (book, website...), so I don't mess up badly.

[@ronamedee2475]

Lots of great information. Thanks

[@erichoehn3669]

Thank you

[@otpyrcralphpierre1742]

I think it would probably crack less if you used Distilled water to make your mix.

[@Ben-qv9td]

Thanks for all the great info! If I have already applied the rigidizer to the kaowool, would I still need to apply a layer of Satanite?

[@robinson-foundry]

Ben No problem! Yes you do. Rigidizer is simply to make it easier to coat the fiber with something like Satanite.

[@adrianakuzmikova1697]

@@robinson-foundry where is ceramic wool? can you cover it with this directly? will it not tear the wool if it cracks?

[@robertlombardo8437]

Question. I live in the desert. And right now it's August and temps reach 120°F or more during the day. Could I just leave the Satanite out in the sun to cure? Water doesn't stand a chance against that kinda heat. Thanks for the instructions. I just purchased a full set of high temp kaowool from these guys, plus Satanite and a refractory coating. My foundry is gonna burn like the core of the earth!

[@robinson-foundry]

I’m in Vegas so I know exactly what you mean. I found that drying the satanite slowly is best. After coating your wool, let it dry slowly in the garage. If it drys too quickly it will crack. Good luck on your furnace!

[@Tinkering902]

Would have to be a good idea to use satanite as a mortar between soft firebrick, or would it be better as just a coating for the inside?

[@robinson-foundry]

I believe it can be used as mortar but you’d have to check to make sure.

[@untermench3502]

Some issues I had with cracking due to shrinkage was to add some Lithium Oxide, which has a positive temperature coefficient. In my case it was about %5. If you add too much, you might get compression fracturing. I have used a lot of Kaowool in my projects, but I noticed it was very suceptible to Borax fumes. A thin coating of fiber free reractory seems to help.

[@alexwalker8422]

Satanite is very likely designed to increase its own demand, easy fixes are easily within reach of the engineers who designed this product.

[@untermench3502]

@@alexwalker8422 Speaking of design. I tried successfully to work-up a mix using components from a pottery supply. It was more expensive than a commercial mix, but I wanted the experience. My earliest furnace was an electric one in 1972, using a commercial refractory mix and it worked well. It was a prety easy exercise since I had worked as a technician in a Ceramics lab. I have to admit that using a proven commercial refractory mix is the cheapest and easiest approach, but if you want the experience and you have a lot of free time, go for it.

[@soullimbo]

could you use this as a mortar between home made perlite bricks?

[@montycollins4886]

Great stuff, thanks for the video, have subbed on as well.

[@bruceveneziani]

Ive watch both of your furnace builds. On the keg build you used ITC 100HT as a rigidizer. which is better and more durable?

[@robinson-foundry]

Hello, I would recommend Satanite as a coating for the fiber and then ITC100 over the Satanite.

[@TheAce5255]

My Vevor propane forge came with two hard refractory bricks. I've heard that these absorb a lot of heat. If I coat them with Satanite, will they absorb less heat?

[@iSam3000]

I really want to know what product you would recommend to do this for soft ceramic fibre these days? Trying to get hold of green patch in the UK is impossible

[@lynnchandler3116]

Thank you for the information!

[@timdunk7278]

Thanks for thoroughly sharing your experience and attention to detail. I noticed other comments about using rigidizers on the kaolwool... Is this step required or does the satanite bond better to wool without?

[@robinson-foundry]

You're welcome. I have never used a rigidizer. In my experience, satanite sticks well to kaowool by itself. Lightly misting the wool with water before application helps a little. Just dont keep going over one spot with the satanite. Good luck.

[@AS-ug2vq]

Kaowool is not a structural material. If you wet it with a neutral solution of sodium silicate (also called colloidal silica), after firing the fibers are locked in place. It has two benefits, one is that fiber will not dislodge into air and enter lungs. Another is that the wool will not collapse with repeated heating and cooling cycles and will take fair bit of load due to fiber locking in place.

[@prankcollar2921]

Use aqua net generously let dry and apply satanite

[@YoGooN1]

Thank You!

[@chefboyrdanbh]

Could you use it in a pizza oven? Would it be safe?

[@christopherconkright1317]

can i apply rigidizer and then this to the front just so the whole of the ceramic blanket is not giving off any fibers

[@williamdodson7874]

are we coating ceramic fiber to trap particulate or to increas heat resistance ? i coated with clean burn refractory , seems powdery after set ? will the satanite lock it down ?

[@adrianakuzmikova1697]

where is ceramic wool? can you cover it with this directly? will it not tear the wool if it cracks?

[@catherineharris4746]

Nice!👍👍👍

[@tonyhowe3676]

Where did you buy the satanite from??

[@jamesdeeton4299]

I bought some Satanite and wondered if I needed to buy extra stuff to harden it but now I know different. But would Teflon additive make it work better?

[@3vanguardofthephoenix335]

Isn't Teflon toxic? Excuse my ignorance, but I'm new to casting and just want to make you're safe ^.^

[@jesusvalenzuela81]

I just got a forge for knife making and a tub of this powder came with it the forge walls are this really thick fabric white in color do I need to use this stuff on the fabric?

[@3vanguardofthephoenix335]

Yes, after applying a rigidizer. It's recommended because it stops tiny ceramic fibers from being blown out of your furnace. You could potentially get serious lung damage from inhaling said fibers, thats why it's good practice to coat your furnace. Hope this helps

[@victoryfirst2878]

What is the temperature this can take ???? Thanks

[@hirendesai6473]

Do the bolts and nuts holding the ceramic blanket on the furnace cover expand and contract due to heat? If so, how do they remain threaded on to each other?

[@dwayne7201]

From what I understand you apply a rigidizer to the ceramic blanket so it doesn't flex Once installed The bolts are likely just there as pins to keep it in place.

[@ShopperPlug]

Explain what it's used for. Why we gotta use Satanite ?

[@supersneakyshrub3975]

Late response but: Satanite is used as an insulator so that your rockwool or bricks aren't directly being exposed to the heat. It makes them safer (the ceramic fibers burn and break off when exposed to heat and can cause silicosis when inhaled), and last longer. It's cheap, it'll make your forge or foundry last longer, and it'll make it safer to boot.

[@josephdupont]

can i use this to coat regular fire brick... can you you use it to fuse the fire bricks together.

[@robinson-foundry]

Joseph DuPont I believe you can use it on regular firebricks and it is supposed to be a mortar.

[@DoctorTooploop]

[@MrTim3990]

Why do you coat the cast-o-lite 30 with satanite.

[@jrocks1971]

There are different grades of kast-o-lite. 30 is rated for 3000 F, which (I believe) is the top temp you can get it to withstand. Satanite is rated to 3200 F, so it can take a higher heat. Lots of forge and foundry makers will use some castable refractory like cast-o-lite 30 for the main walls, then coat the inside with Satanite, which increases its heat rating and insulative capacity, while protecting the main casting. When the Satanite wears off, chips away, etc., just brush over it lightly to clean up the surface, vaccum it clean and add a new layer. That way, you're always just touching up the surface, instead of having to do major repairs to the casting or re-cast it altogether. If you want even higher temps (and faster to get that hot), coat over the Satanite with ITC 100 -- or other high-alumina IR-reflective coating. If using Inswool / Kaowool ceramic blanket insulation, line it with that stuff, then apply rigidizer (spray/paint-on liquid), dry that, cook it in a bit to 100% dry it, then coat with Satanite, cook in each layer with low-burns and allow to cool -- a couple times each layer, then ITC 100. That keeps the particles of the Kaowool from getting broken down and airborn (i.e., giving you lung cancer) and protects it - same as with the Kastolite -- just clean up the Satanite and re-apply to keep'er in top order.

[@ericsprado4631]

Can I coat KO wool in my forge with this?

[@arkonwolves7192]

You certainly should and I just did so I imagine you can its the same concept as any other refractory. Mr Volcano sell satanite as an add-on for their forges so yes.
