I am looking at upgrading my skutt kilns to the newer touchscreen interface. Pretty straight forward process. But can you use one of these interfaces on on a competitors kiln. I have a couple old olympics of similar size, ect to a 1027. They are about to become, individually zoned, relayed, ect. Perfect time for an upgrade. I know Bartlet has the Genesis programer, but I like continuity if I can get it.
Hello everyone, I have bought a second-hand electric Rohde 5024 Kiln (230V) and a TR 305 controller. I have done only 2 biscuit firing at 950C and noticed the pieces were almost vitrified; our mocal clay is rich in iron oxide. I recently did a slow glaze firing at 900C and my work melted down, some kiln shelves are distorted and even broken by the heat. The kiln electric plug is stick to the wall socket.Do you have an idea of what has happened? The whole situation is devastating as I live in West Africa and do not have potters, technicians or manufacturers who know about electric kilns. I have contacted the manufacturer and they said they could not help. I am not familiar with kilns and hope someone could help with the matter.Thank you so much in advance
Hello everyone, I've started dabbling in pottery about three years ago, making bonsai pots. This fits with another hobby of mine, you can guess which :). Point is, after firing my works with some acquaintances, I've decided that my own kiln is a must in order to really progress in the craft. The problem is that I my backwater location the chances of buying a second hand one are next to none, and I can't really justify spending almost $2500 for a new one. So I came up with the idea of actually building one from scratch. Yes, I know it's hard, yes, I know it can be dangerous but I'm trying to be as smart about it as I can and mitigate all the risks as much as I can. I would really appreciate it if you ladies and gentlemen would be willing to part with some knowledge to help me have the best possible outcome for this project. Now for the tech specs: In order to fit the nature of my work, I would need a 50x40x30cm interior. (19.7x15.7x12 inches) The temps needed would be around 1240°C (2264°F) The power I can get away with as a household consumer in my location is 230V 16A ~ 3600W This takes me to my first point: As far as internet wisdom goes, the Wattage needed for a pottery kiln is 0.6W/cm2 which would place me at a needed Wattage of around 5600W. Waaaay above what I can provide. But then I read specs for kilns produced on Germany like Nabertherm that for a 60L pottery kiln with a top temperature of 1300°C produce single phase 230V 16A models, which makes me believe I can do it. I'm assuming that I'll need to go with more insulation and longer firing times, but it's doable. Is that accurate? Next up, elements: luckily I have a provider for Kanthal A1 wire near me and prices are decent. Would 1.6mm 1380°C max, 0,721 Ohm/m be suitable? With this diameter I seem to be able to juggle the resistance, wattage, length and placement of elements as close to optimal, with 2 elements running in parallel. Thirdly the most amusing topic... Well not amusing but maybe the most complex. The controller. Being in IT i'm a sucker for gadgets. Usually buying them, true, but this time I'm thinking about building :). I saw a lot of projects on the web with Raspberry Pi kiln controllers. The features they provide, the adaptability and the connectivity of the systems sounds amazing. Question is: does anyone fire with something like this? How does it compare to commercial controllers that are super expensive and in the stone age as far as features go. Are they worth the trouble? An example project that stuck with me is below. But there are many more Thanks for the help, and looking forward to chatting with you. Mihai
