In addition, you can top up the container with water to keep the clay from drying out. (68°F -72°F) Bake at 250°F for several hours until no steam or smoke is coming out of it. Refractory Cement. Curing is done by applying heat, but take care to cure it as slowly as you possibly can. These materials have some serious downsides that I think don’t get discussed enough, but that is beyond the scope of this article. This high alumina-silica refractory mortar is made for laying firebrick. But if you are looking for an “optimal” forge, I think soft fire bricks are a step up in many ways. But as I said earlier, there is a lot of overlap between the two designations. Despite this, I did manage to find one hard brick with a high heat tolerance online. http://www.craftkb.com/Uwe/Forum.aspx/blacksmithing/802/Repost-about-rigidizer. While this is a pain, there are some general rules of thumb that will allow you to quickly buy the brick you need for your project. While there is significant overlap between soft fire bricks and IFB’s, I find I have much better luck finding forge quality bricks when searching for IFB’s. This is common to all refractory material coatings. A note about ITC-100 refractory used to coat the kaowool, it works by far better than any other cement/mortar like refractory I have used in previous forges. Most hard bricks have a lower heat tolerances than the soft fire bricks. This means they are less likely to break due to heat stress. In addition to the fire bricks themselves, there are a number of different products that can be used to enhance your forge or smeltery. Soft fire bricks also tend to be rated for higher temperatures. 4 parts Perlite + 1 part fire cement. After air drying, Rigidizer provides a harder and resistant, but less resilient, surface on the material being treated. Most homemade forges cannot reach forge-welding heat without an application of ITC-100. It can also be used as a clay coating for developing "temper lines" (hamons) on your blades. Next, apply the Satanite to the wool using a paintbrush, covering all exposed wool surfaces. First, let the forge sit for a few hours minimum to air dry a little, then fire up the forge just briefly and shut it down. *I talk about standards a fair bit in this article, it has been brought to my attention that the ASTM does have standards when it comes to refractory materials. Avoid freezing, but if it occurs, Rigidizer should be thawed thoroughly and remixed. The internet will most likely not cut it as a resource for this level of casting, you are going to have to look through textbooks that explains industry level casting. This brick has a lower heat tolerance coming in at 2700 degree Fahrenheit, but it has lots of good reviews. FOR DIPPED JOINTS: Add approximately 3 ½ gallons (U.S.) (13.2 liters) of water per 100 lbs (45.4 Kgs). Which begs the question, do you need refractory brick for casting aluminum? Sadly this page is missing a fair bit of product info. I purchased my ITC-100 a while ago and haven't used it yet. Recommended for use as a primary hot face refractory lining or as back-up insulation behind other refractories in furnaces, kilns, flues, refining vessels and heaters, regenerators, gas producers and soaking pits, stress relieving furnaces, reactor chambers … If I recall correctly, they were at one point advertising that this cement didn’t need to be cured. It can be hard to find hard fire bricks that have a high heat tolerance. ➡️ Forge is now sealed, protected, and ready to use! When I look for IFB’s on the internet, I will often find bricks rated up to 2500-2800 no problem. If desired, drying time for thin application may be shortened by using slightly higher temperatures up to 150° F. On some surfaces, two coats may be required to obtain desired hardness. This is SCREAMING hot for a blacksmithing forge. 1 part Furnace cement + 4 parts Perlite. This castable refractory cement can be used for gunning, casting, troweling, or extruding.
