Welcome to Understanding Pottery, Chapter 14: Gas Fired Kilns Part 1.
This is the second of a four chapter series on Pottery Kiln Design, Construction and Operation with this episode focused on Gas Fired Kilns. Are you curious about different methods of firing pottery? This month we focus on gas firing with an overview of the fuels, burners, kilns, and firing procedures. How does natural gas differ from propane? What are the features of the different burner designs? What are some good practices for firing?
The next topic in the series is Gas-Fired Kilns Part 2.

This professor is entirely on point with content and teaching style. He’s easy to listen to simply because he’s so knowledgeable and his lesson just flows. He doesn’t even let the late students interrupt his train of thought. Awesome!!

Great info Phil, I remember my first downdraught gas kiln. The guy who built it was in the city 5 hours away. When I fired to 1300 I would get to 1200 and it was like hitting a brick wall and no matter what to get to 1300 was trying every trick in the book . I would ring the manufacturer and we would go over everything again, him saying it was only inexperience etc. Well one day I had had enough and rang him again; he thought about it and said, get under the kiln and look for a number on the side of the venturi. Well it turned out he had put 1 inch tubes on instead of 1 and a quarter inch. Huge difference to gas flow. It was a 30 cubic foot kiln and was no trouble after that. I can remember firing on cold nights from 100 pound bottles and losing pressure due to icing up and having to hose down the bottles with water to warm them up . The same person built my 100 cubic foot trolley kiln and it is a pleasure to fire, mind you I am still learning. The first kiln I had was a self built wood fired downdraught. From the Olsen kiln book. I had had a long break from pottery and am now getting my studio back together. I have learn't so much from you Phil in such a short time. I remember the mistakes I made and learnt the hard way. Somehow all the hours and work panned out and I was able to make a living from it but I sure wish you were at my side back then .thanks for your experience and teaching Phil it means a lot to people like me who live in the middle of nowhere, thanks and kind regards from John.

John, thanks for sharing your experiences! We call these talks 'Round Tables' in hopes that the discussions will go both ways.

This was very helpful! Thanks so much! Been firing propane gas only for the last 5 years and I still learned a bunch of new things! Nice job! I just got a used olympic gas kiln 2831g I hope to fire soon.

@WashingtonStreetStudios 3 года назад

We have a forty year old Olympic gas kiln, not sure of the model, but probably similar to yours. The video Operating a Small Gas Kiln (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--Lyqza6anAs.html) was made based on operating the same kiln. And the video Reduction Firing in a Gas Kiln (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uxIYUCD2qk0.html) is a general procedure that is applicable to all gas kilns. We hope you are enjoying the channel, please share it with your friends and fellow potters to help us grow our community!

And we love you back! Next weekend, September 12, we have a livestream of 'An Introduction to Glaze Testing' which will be published as a video. It will be 5am (i think) where you are, but hopefully you can join us!

Hi Phil: thank you so much for your teachings, I’m learning a lot and clarifying many questions I had. Currently I’m firing an Olympic Kiln 2831G with propane, low pressure (will built my first gas kiln with hard bricks next year). On pressure regulator it seems you put it right before the kiln; in other words the pipe line from the gas tank until the pressure regulator has the full pressure of the tank. Is that so? Normally I’ve seen the pressure regulator installed just by the tank and the gas line goes with the lower pressure upto the kiln. With regards to Baso valve, the 2831G has just one Baso valve that connect a ring pipe to the four burners, could I use the same system for new hard brick kiln (4 burners, 30 cu.ft.)? Thanks very much.

I sent this question to Phil and will post his response when I receive it Thanks for the question.

Hi, I want to make a kiln out of a galvanized trash can. I've heard that galvanized steel gives off a gas at high temps. If I use it outdoors is itt safe? This would not be a raku kiln but a bisque and glaze kiln.

@WashingtonStreetStudios 2 года назад

I've not heard of anyone getting to bisque or glaze temperatures in a galvanized trash can kiln. We repurposed an electric kiln to be our raku kiln. We prefer to use materials for their designed purpose. Sorry we can't help you here, please research this fully to make sure it's safe.

@tri-forceblades3123 2 года назад

I have been researching the safety issues when using ceramic blanket (kaowool). Is it necessary to coat the ceramic blanket with refractory cement or satanite to reduce the emissions that can happen when your kaowool reaches high temperatures?

@WashingtonStreetStudios 2 года назад

I personally can not answer and suggest you contact the manufacturer of the blanket for their recommendation. We did not coat the ceramic blanket and try not to 'disturb' the blanket when we are firing. Unfortunately, Phil passed away last July and he probably could have provided a better answer. Thanks for the question and let us know when you get an answer!
