Welcome to Understanding Pottery, Chapter 16: Gas Fired Raku Kiln.
Got an old electric kiln that doesn’t work anymore? How about turning it into a raku kiln? Gas-fired raku kilns are generally simple in design and small in size. As such, they are easy to construct using metal barrels or old electric kiln bodies. This discussion is about methods, materials, and equipment used to construct gas fired raku kilns, and also about tips for successful firings.
The next topic in the series is Kiln Performance Problems.

Hey, thanks for the videos. Phil mentioned only needing a torch and a regulator, is a flashback arrestor not needed when using propane?
@WashingtonStreetStudios
@WashingtonStreetStudios 5 месяцев назад
Unfortunately Phil has passed away. He could have answered with more authority than I have. I believe a flashback arrestor is used with a torch, and Phil talked about a raku burner. Burners do not need a flashback arrestor.

Can you use this type of kiln for cone 6?
@WashingtonStreetStudios
@WashingtonStreetStudios Год назад
It would be very difficult to get the kiln to cone 6 temperatures. It is also difficult to control the speed of temperature rise, if you could get to cone 6, you would probably lose pots during quartz inversion.

@WashingtonStreetStudios
@WashingtonStreetStudios Год назад
Great question Sybille Stahl, You can use the Kemper high temp 17 guage wire, and it will work for quite a while. The nickel chrome high temp wire withstands higher temperatures and will hold up a bit longer, although it could be overkill for a raku kiln.

Thanks for the video! When is coming raku glaze recipe special?
@WashingtonStreetStudios
@WashingtonStreetStudios 4 года назад
Niko, Thank you for your question. We, at Washington Street Studios, even with a glaze chemistry expert like Phil, use commercial Raku glazes! Many will disagree and you probably can get better or more specific results if you formulate your own glaze for Raku. We use commercial glazes because we have found they produce good and predictable results, or at least as predictable as you can get in a Raku firing! There are so many variables in Raku and the firing process that simply working with a small variety of commercial glazes you can create a multitude of results. We have five Raku glazes at our studio and they provide enough variety to keep us all happy. The short answer would be shop for commercial glazes. If you have a specific question on Raku glazes, we will be glad to provide an answer. Feel free to post a comment with any question you may have.

Am I supposed to dry clay greeenware then add color dry and fire it altogether? Or do I fire clay first then add color and fire again?
@WashingtonStreetStudios
@WashingtonStreetStudios 3 года назад
Samantha, I'm not sure I totally understand your question, but I can explain our Raku process. I assume your question relates to raku since it is on the raku video, if it's not, you might want to watch this video (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VP-dgfmwrBE.html). For Raku we throw the pot and you can add washes, stains, slips or engobes as explained in the referenced video above, then we bisque. We use a Raku glaze to decorate then we fire as explained in the video. I hope that helps.

@@WashingtonStreetStudios ok I think that answers if I needed to fire first to bisque then later add color glaze I wasn't sure if I was to dry clay first fire it then add color or raku items and fire again, I suppose I need a way to bisque my clay but I don't have a way to do so I have a microwave kiln for jewelry peices but not for small pots and phone holders, I have tried 5 in a small hibachi using sawdust but it doesn't work well. Thanks I'm hoping to buy something soon, so we can just use torch etc. Thank you for the information and link I will watch Incase I missed something

Thank you for all your explanations, they are very helpful. I just made my first kiln for Raku and I pretend to use it as regular gas kiln; can I use it for bisque firing?
@WashingtonStreetStudios
@WashingtonStreetStudios 3 года назад
It's theoretically possible to use it for bisque firing, but you must be very careful and certainly not recommended. Raku kilns heat up very fast and you need a very slow ramp up of heat for the bisque firing.
