Hi all! I just finished converting an old electric kiln to gas. The firing will be totally manual, no kiln sitter involved. Having never fired a gas kiln, I know my learning curve will be steep! But I need a few pointers to get started. I want to start out with a glaze firing, ^5, mainly because I don’t have any greenware to bisque right now. I have a few “sacrificial pieces” that I am willing to use to start the learning process. I have a pyrometer and witness cones ready to go. So, my main question has to do with ramping at this point. How fast do I want the kiln to increase in

Since day 1 I wanted to do wood firing. I started with an electric kiln and although it is possible to do interesting things I'm still focused on ultimately doing Anagama. I cant truly test Cone 10 glazes in my electric and want to get as close to possible to that environment, which means a way to do reduction, neutral and oxidation. So I got a broke down Duncan kiln donated to me and the burner came in today so I'm super excited!!! Stripping it down tonight and getting the elements out then will figure out how to cut the burner port and the top opening. Then I have to find a 40 - 50 gallon ta

Hi, I currently do smoke firings in an oil drum, fired with wood, but I would like more control over the temperatures reached. I’m thinking of building raku kiln from another drum and trying saggar firings. One question I have is about regulators. I had always intended to use a high pressure regulator but have found it difficult to source an inexpensive change over regulator (I want to be able to connect two gas bottles up) for high pressure systems. There seem to be plenty of change over regulators for low pressure systems, so I was wondering if it would ma

I know this kind of thread has been done many times. I've read lots of them, watched lots of YouTube videos and clayart topics. From this I have learnt there are many problems with this kind of conversion. I have never fired with gas, but I love the look of reduction glazes and my old electric kiln was nearly dead anyway. Following a recent house move I faced the prospect of a costly electrician bill to install it in our outbuilding, and decided that converting it to gas would be comparable in cost. Initially I was going to do an updraft kiln. After reading many uneven firing woes I

I have decided to take the leap and build my own studio. I want to put in a front load gas kiln and would like input. I searched the forums and unless I missed it, I couldn't find much on gas kilns, so forgive me if this topic has already been addressed. I have been looking at the Olympic DD12 and the Bailey Front Load Standard 18/12 and I have also talked to Seattle Pottery about their Crucible front load kiln. The Bailey is about twice the price of the Olympic and the Crucible. My plan is to have an attached shed on the studio in which to put the kiln. I live in Montana so it will need to be

I am rebuilding an AIM Gas Kiln model 2327G (About the size of a Skutt KM1027). I'm looking for help in finding a operating manual or copy of original instructions. I called Aim and they don't have instructions for the older gas kilns anymore. I'm interested in if there were baffles originally at the bottom of the kiln to redirect the flame. It has 3 Gaco 75,000 BTU burners and is set up for Natural Gas. It's about 20 feet from my Gas meter on a 3/4" line. Any input or help would be appreciated. I intend to fire at Cone 10 reduction.

Good Afternoon, I'm using a Paragon HT22 kiln with the Dwyer gas inlet flow meter. I'm producing small wire springs (stainless steel) that need to be heat treated in order to secure their final form. In my regular smaller kiln, the oxygen in the atmosphere is reacting with the heated stainless steel and results in pretty intense discoloration (brown/dark purple/etc). Using my new kiln with a tank of Nitrogen gas hooked up, I am able to produce springs that have only a slight blue discoloration. This drastic reduction in discoloration/oxidation means that the nitrogen gas is working -

I am struggling to control the heat rise of my gas downdraft - it gets too hot too quickly! I'm test firing empty (I've put in all the kiln shelves) to learn how to control temperature. I'm trying to emulate a slow bisque as I will be firing large, thick sculptural pieces. I'd like to control heat rise to 20 - 30 deg. C per hour, particularly for the first 100 deg. The slowest I've managed is 200 deg. C in 30 minutes! This is with one burner lit, at it's very lowest setting (the flame is JUST clearing the port inside). The top of the kiln heats really quickly and after 30 mins., t

Hello everyone, I am new to this form, and new to kilns. last week i started trying to make an updraft gas kiln, and it seems i hit a wall that i need some help with. Setup : Kiln inside size : 9" x 18" height 15" first shelf @ 6" Bricks used : Firebricks/ refractory bricks 9x2.5x4.5 ** Dry stacked ** Gas : LP Temperature : K type thermocouple sensor (0-1300 c ) positioned at 9" height on the sidewall and sticking out 1.25" (https://www.amazon.com/gp/product/B00UWVZAY8/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1) The problem : I cannot get the kiln to go more than 12 -
I recently paid off my student loans and bought a house so I decided to dig my ceramic equipment out of storage where it has been for the last 15 years. While doing schooling and an internship in ceramics I bought a second hand little Amaco Gas Kiln Model # AG40 Serial# 192 . I loved this kiln because we did many raku firings with it at the pottery and I would love to repair it and fire it up again now that I have space. The issue is that I can not find any information on the kiln and I am also in the process of cleaning up and repairing the burner. I was wondering if any here heard of this

I have found several pages that all repeat the same: OK, fine by me Lets say we have a 250 l kiln (9 cf). We are going to need 16000 x 9= 144000 BTU We know that 1 Kg of propane packs about 13.97 kWh or 47668 BTU So, 144000/47668= 3.02 Kg (6.65 lbs) of propane per firing to cone 10? (I am using weight and not the volume because volume can be anything if exact pressure and temperature are unknown) Q 1: How close is this to actual gas usage? About the downdraft kilns and actual stacking area. Q 2: Is it safe to say that 250 l total inside volume will give us onl
