  • Ceramic blanket is a suspected carcinogen. For that reason it must be ridgidized to help protect you from it. This video shows you the process and how to make your own ridgidizer.

    PLEASE READ:
    DO NOT use fumed silica to rigidize your ceramic fiber blanket. I understand it is accepted by many "blacksmith experts". And I mean no disrespect towards the gentleman who made this video, or anyone else. It comes down to inorganic chemistry. Please read.
    The reason we need to rigidize ceramic fiber blanket is to prevent the tiny silicate particles from entering our lungs. They are very bad. If you want more info on it, Google it.
    Ceramic fiber is made from Silicon and oxygen bonds, basically. The silicon and oxygen may form many linked bonds (hence larger fiber) or they may form a few (invisible fiber). It's a mix. But, these fibers are not connected to each other very well. Think of a jar full of small marchmallows. That's fiber blanket. Now heat it up and melt off of it-that is rigidize blanket. Kind of.
    To prevent the fibers from breaking off and entering our lungs we need COLLOIDAL SILICA. Colloidal silica IS NOT THE SAME AS FUMED SILICA ADDED TO WATER. IT IS NOT EVEN COMPRABLE. in fact, fumed silica is the exact same chemical structure as the silica dust you breath in. If you use fumed silica, you are only making the matter worse.
    Colloidal silica consists of tons of silicon atoms bonded to oxygen atoms and hydroxyls, in a repeating manner. Over and over again. They are massive molecules. When you apply it to ceramic fiber it will bind to the oxygen atoms of the silica, hence literally binding each fiber to a very durable and sturdy mass that will not let go.
    Please, do not use fumed silica for rigidizing. You are actually better off not using anything. Fumed silica is exactly what we don't want to breath. To make colloidal silica from fumed silica, you would have to add sodium hydroxide, heat it up to a ridiculous temp, then use diffusion or chromatography methods to isolate it, as well as the aid of catalysts. It is NOT made by adding water.
    Stay safe. Verify what you are told. If you don't know how to verify it or are not willing to, pay a professional to do it.

I did buyn some ceramic wool blanket for my hot box. Since i dont want some mass manufactured thing newho. Anyhow i could write a story. Just buying silica ashes, or fumed silica, lolI learned a shit ton about oils and coatings and a world of oils and endless blends i never imagined. I hope someday people can have good times together without knowing whats gonna happen. I love cooking, its similarly creative. My slurry for keeping the coat from shedding was the silica powder, a touch of gypsum or pop, . I surf as well . As knowing resin/Epoxy/Fiberglass for repairing. The world is becomming asmaller place and less confusing the more i know and see and experience resins form, recrystalize, hardens. I lined by Top half today with Blanket and a shitton of Silicate.Yes Today.. I don't know nor think it will be much different than the reaction to make surfboard resin. once done. I saw all its uses from some ad and was impressed. This stuf weights grams for a quart of it. truely awaiting results.

    • @irondaggerblacksmithsupply1237
      @irondaggerblacksmithsupply1237  3 года назад +1

      no. if the rigidiser is not fired after application, it will eventually dry out and begin releasing from the blanket. If you were to heat it to 2k degrees after applying rigidiser then it will work. however it will not be very flexible. If you go that route I suggest prepping and firing a 2" square piece first so you can see how it behaves afterword. Also by adding more silica to your water mix the more "foam" like the resulting fired blanket will be.

      It depends on if any airflow gets between the metal. If it is sealed and enclosed in metal in theory it's safe (it's kind of like asbestos as long as it is not disturbed in anyway it can not send anything airborn) if it is at all "open" yes it needs rigidised for safety.

I have never used the refractory sent with the devils/hells forges so I can not speak to it particular. However all refractories I have ever used that I would call "quality" stick better to the blanket when it is "buttered" or wet from the ridgidizer.

      do you mean as an insulation to shield the piping? or do you mean forming the blanket in to the piping itself? either is possible especially if you coat it in a refractory cement after. Before attempting however I would highly recommend consulting the manufacturer to make sure that it will hold up for the particular type of work you need.

    The silicate in water is basically "pottery glaze". It will dry to a clear hard solid, but if you don't fire it, moisture from the air will attack it, pitting it. I think the firing is not a chemical reaction, but rather something like driving off water hydrates or such, as in firing bricks, but I'm not a chemist. Similar silicate solution was coated on the carbon-carbon leading edges of the Space Shuttle wings. It melts around 1200 F (like glass) but still provides thermal protection as a liquid and likely also gives environmental protection.

    • @irondaggerblacksmithsupply1237
      @irondaggerblacksmithsupply1237  3 года назад

      nope. As the silica is fired it turns to cristabolite(sp). this form bonds it to the blanket. if left untreated at this point. as you use the cristabolite(sp) would clump and break off exposing the blanket under and making it unsafe. However because we coat the treated blanket in castable refractory it is not able to break off and sits there. over time eventually even coated in refractory it will breakdown (this is why forges must be relined) However the silica will not melt untill it cross the 3k+F threshold. behind a good refractory it will never reach that temp. www.quartzpage.de/gen_mod.html

      Thanks for the reply. I was probably thinking of the "softening point" of silica glass, which is 1550F, whereas the melting point is 2075 F and when transitioned to quartz (SiO4) becomes 3101 F. I tested some silica solution 15 years ago, which was provided by the company who made the Space Shuttle carbon-carbon wing edges to see if I could bond thermocouples and strain gages with it. It worked, forming a hard clear coating, but after sitting 6 months in my office (unfired) it turned milky and brittle, which I assumed was from moisture in the air, but perhaps another reaction over time. A higher-temperature fiber is alumina, which in pure crystal form is sapphire - Al2O3, 2nd hardest to diamond. In nature, impurities make it the sapphire or ruby gem. Alumina fibers are used to insulate thermocouple wires (Nextel is one brand), though is brittle and the fibers are short so needs a binder. Alumina might be the main constituent of these ceramic blankets. The company also mentions kaolin, which is the coating on glossy paper, also termed "China Clay".

    Hello
    What is meant by the classification temperature of the ceramic fiber 1260?
    What is the melting point of these fibers and what are their tensile strength properties?

    • @irondaggerblacksmithsupply1237
      @irondaggerblacksmithsupply1237  4 года назад +1

      that is all very dependent on the brand/style of ceramic blanket. Most of this data can be found on the MSDS for the blanket you purchase. This is particularly important for the melting point of the blanket, check with the maker for the specific blanket you purchase. The one I use in this video I believe is 8# 1" rated for 2800F

    Hey thanks for the video, I didn't know this stuff existed. Of the store bought brands are there some that have more or less silica? Or what measurement should I be looking for? Also some say they're only good for heat up to 2300f which may not be as high as the my forge temp gets to. Any suggestions?

    Thank you for the information. I had putchased factory-made rigidizer since I was unable to find that fumed silica in Europe. Following the information in the comments I have been able to find aerosil 200, used as thickener for epoxy/poliester resins. So you have a new subscriber. Could you speak about mixing proportions with eater/food colorant?

      the idea is for the rigidiser to soak in. thats why you color it, that way you can see how far it has penetrated. I don't believe there is such a thing as over doing it in this stage. the more silica you get in the blanket the more bonded it will all be.
