My Brass Melting Furnace made from the shell of a crock pot. Although I got a late start on getting footage when I first started the furnace the video shows the remainder of the build. What I didn't get footage of was brazing the bottom onto the crock pot steel shell so not much was missed. This furnace will easily melt cast iron if I use forced air. Watch the video for all the steps involved in bringing the project to completion. Please be sure and check out all my metal casting instructables I have posted. Thanks for Watching!

<p>Thank you! Most informative. I appreciate your &quot;somethin from nuthin&quot; it makes all my junk appear more valuable. Would it be possible to get specific on the materials you used? Specifically the &quot;wool&quot;, type of furnace cement and ceramic used. I don't want my ignorance to blow up or burn down the shop. Thanks!</p>
<p>YW! </p><p>Shoot me a private message and I will go into some detail on the supplies used. I have plans to see if some of these suppliers will &quot;sponsor&quot; some of these vids by providing supplies and until I find out what they have to say dont want to do any public advertising for them! :) </p>
I recently built a furnace for making and casting bronze; this is an interesting variant. If someone doesn't mind spending a little money, you can get a helium tank (intended for balloons) at a store like Target that makes a great shell. For $25 you can get one that'll work for a crucible up to a #8 and a larger one is available for $40. For my furnace, I used castable refractory for the bottom and lid; the wall is 1&quot; kaowool.
<p>I have Carbon Dioxide tanks both small &amp; large I could cut up for crucibles if I wanted. I get fire extinguishers for free so use those for as crucibles for my metal casting. Good for 8-10 melts or so.....</p><p>Yours sounds like a nice furnace....thanks for watching!</p>
I had meant that you can use those helium tanks for the shell of the furnace; they are essentially the same thing as propane tanks without the danger of the propane. My reference to crucibles was simply a way of showing the relative size difference in the furnace you would have between the two tanks.
<p>Ahhh, I misunderstood! LOL </p><p>Absolutely, I am hesitant on cutting up propane tanks myself. I have 5 gallon steel buckets as well as 30 gal steel drums I coulda used but wanted a small furnace and thought using a crock pot shell would be rather interesting :)</p><p>The outside of it doesnt even get hot enough to melt the paint, works great</p>
