Looked at Lowes, Home Depot, and Harbor Freight for a metal cart to place my kiln. After looking for about a month, I found this typewriter table on ebay for around 50 big ones. The lady that sold the table did an excellent job packing it and placed labels on it so it was fairly easy to put together. The table is in great shape although it has a couple of dings. I lined the bottom shelf and drawer with shelf liner. Also placed a board on the bottom shelf for more storage room and lined it with shelf liner as well. The kiln weighs around 45 pounds and wondered if I need to place anything underneath the kiln, or will the table be okay? I've seen some pics of older kilns with firebricks underneath them, but this one has the rubber feet.    www.ebay.com/itm/Vintage-INDUSTRIAL-TYPEWRITER-TABLE-drop-leaf-metal-tan-mid-century-modern-stand-/321634387593Thanks for checkin' it out.  |

I can't offer any advice, but it's a good find. Nice setup!

Thank you for your kind comments, iant! I have a fire extinguisher just in case, but want to make sure not to toast the table top. |

I like it! Good way to re-purpose that table. Good deal & U B smart.
Does it feel top heavy? I mean can you rock the kiln easily? Some weight on the bottom shelf couldn't hurt, but I don't know that you need it.
I guess I missed it... what do you use the kiln for?

Thanks, captbob, for your nice comments and suggestion to check to see if the table is top-heavy and to add more stuff on the bottom shelf. I think it will be okay as long as I don't move the table around much. It will jiggle a bit though. I wanted to teach myself how to fire different types of metal clay in it since there are limitations on what you can fire with a butane torch. Then try firing other materials if I don't burn the house down in the process. manofglass has also given me some ideas since he has two kilns. Wonder if ceramic tile underneath the kiln would be alright to use? |

I don't have any direct experience with a kiln, but I frequently use a muffle furnace at work and it appears to work in sort of the same way. Most of our tests are run at 800C (just under 1500F) and the outside isn't super hot when its running. For safety sake I'd put a ceramic tile underneath it, but I don't think you need to use fire bricks.
Take this with a grain of salt though! If anyone has more experience, go with their advice.

Thank you, Fossilman! Many thank you's for your advice to place a ceramic tile under the kiln, blackout5783! We have some extra tiles that I could use. Is a muffle furnace a type of kiln? What do you use if for? Do you have any pics of yours that you might share with us? |

Thank you, jamesp! It'll reach a temp of 2350* F, but it has a window that has to be 'plugged' for it to reach that temperature. It doesn't need to be that hot for the metal clay, but possibly eggs benedict (ROFL!). It's a Paragon Firefly kiln and one of their smaller models. Santa Rick bought it for me this past Christmas and birthday. manofglass has one that looks like you could fit several large turkeys in it, and maybe even a person. He has 2 very nice kilns and creates some amazing pretties with them. |

far out, love cooking stuff. You may want to try rock, only need 6-700F, with slow ramp up and slow ramp down.
i have trailer trash furnace and have to do the ramping myself. Yours probably has a computer to do that for you.
What is that stainless vessel to the right with a lift hook ??

Great looking table set up! Not sure what type of analysis that Blackout5783 is performing, but generally speaking one would use a muffle furnace to burn away combustible materials leaving the desired material for analysis. For example, they are used to volatize a sample into ash then analyzed for whatever metal you are looking for. This is just one example. They smoke like everything though, depending on what you put in it lol, so it is usually placed beneath a vent hood. They get big-time hot too, so a person needs to be careful taking dishes out of it as well and not cooling them too quickly. Small things make big booms in the laboratory under certain conditions.  |

Thank you for the tip on the temps for cooking rock materials, jamesp. Will definitely give it a try. Didn't you post a chart of cooking temps for rocks somewhere on the forum? If you did, please point it out to me. How do you find out what the temp is in your furnace? I will have to babysit it since it's a manual kiln. One day, Rick took the pyrometer out of its box and was checking the temperature in the house and outside, lol. The tall thing with the initials on it? It's a bank that Rick made for me. I have a couple of different things that he made (while at work, ahem). I guess I would need kiln wash to cook rocks? manofglass? Thank you, ash, and greatly appreciate your explanation! Have you experienced something going boom in a muffle furnace? Thanks, manofglass, for sharing pics of your kiln and work with us! Will you please post a pic of your Quikfire 6 kiln, too? |

Yes. Let me know when you want to bake em up. What is that stainless steel container w/a lift hook to the right of your oven ?

jamesp, are you talking about this?  It's a bank that Rick made for me while he was at work many moons ago. I have a lot of neat stuff he made for me.

jamesp, it has an opening in the top to place coins. It is made of cold-rolled steel. He made it with a rolling machine (at work, lol) and rolled up a tube to make the body of it and welded it. The lift-thingy is a washer he welded to it, lol.

Thank you, ash, and greatly appreciate your explanation! Have you experienced something going boom in a muffle furnace? Only once that I recall. I think it was in a pharmaceutical laboratory where the chemist took out a ceramic dish and it went boom. I don't remember exactly what happened, but I think it was inadvertently cooled too quickly. The other two were from an Erlenmyer flask and a Volumetric flask that the contents were heated too quickly. Rule of thumb, dry the bottom of the glassware well, use boiling stones if possible and have plenty of surface area and as big an opening as possible. It is shocking how loud those little 100mLish pieces of glassware are when they go. Will scare the living crap out of ya and happens in less time than a blink! |

They get big-time hot too, so a person needs to be careful taking dishes out of it as well and not cooling them too quickly. Small things make big booms in the laboratory under certain conditions. I use it for exactly what you described! I work in the raw materials lab of a large cosmetics company. We need to test everything that comes through the door before it can go into a batch. The muffle furnace is used for ROI testing (residue on ignition). We avoid all the smoke by doing the initial burn in the hood with a gas flame, then once everything stops smoking it goes into the furnace. Hot enough to have ceramic crucibles glow orange. Never had anything go boom on me with this, but I did break a dewar a while back and that one was a pretty big boom. A dewar flask is basically a thermos, two silvered glass walls that have a vacuum inside. But we usually use them for cold stuff (like liquid nitrogen) instead of hot coffee. And when they break, they implode because of the vacuum. This one was a 2 liter dewar for a cold trap and it sounded like a cannon in the lab. I was lucky none of the glass hit me in the face, but I was mostly deaf for the rest of the day. And almost needed new pants... Sorry for the thread jacking! |
