Cone 10 Cobalt Blue w/o Soda Firing
sommerjono replied to sommerjono's topic in Clay and Glaze Chemistry
Yes. Currently I have an abundant supply of ash, n. syenite, grolleg, potash, cobalt carbonate, copper carb, r. iron oxide, local red and white clays, spodumene and alumina hydrate (you might be able to tell I have a particular fondness for shino's and ash glazes based on this list). I am willing to buy more materials as well, but I'd like the glaze to be pretty simple still. -

I like to use Veegum T to fix short batches of reclaim. I keep a tub of hydrated Veegum next to the pugmill. After each batch is mixed, I test for shortness, and if needed, put in a small scoop full of the hydrate Veegum and mix some more. Veegum is expensive, but it doesn't take a lot to fix a batch of clay.

Hi SacredDrop, Welcome to the Forum! The motor might need a clean up, and/or new brushes? ...could have a bad switch, faulty winding (particularly if the two speeds are achieved via two separate windings)? Identifying and correcting the problem(s) might extend the life of the motor*. Finding an electric motor shop that can help - I see there are several in the Boise area - might take some looking and luck. Can the motor be repaired? Is it worthwhile? From Boise Electric Motor Repair webpage: "We repair pumps and motors of any kind." *the sparking and heat (and hence, smells) may reduce the life of the motor...

I use a regular banding wheel often when I spray, most often cover it prior with cardboard or often with a small plastic bag over just the head and then set a piece of cardboard. It’s never motorized though, I need to hand spin it for control while hand spraying. I use my medium height banding wheel often. Whatever your final cover is it needs to be absorbent with minimal puddling and stiff enough to resist the air from the sprayer. When I am lazy I’ll just take a low height banding wheel and neatly cover and tuck in newspaper. All result in hand control (which I need) and minimal cleanup at the end of the day. With this setup I hand spray with regular HVLP spray gun (glaze), touch up gun (glaze) and even airbrush (underglaze)

I was gifted an old High School Amaco electric two speed wheel No. 1-101 and every time I switch speeds after I’ve been using it for over a minute, it sparks. Orange and red sparks coming from the motor… I don’t have manual and I have no clue what’s wrong. After throwing for about an hour it starts to smell. Any advice would be greatly appreciated! Thank you!

Hi there! I have a Laguna glaze booth that I'm looking to add a speed adjustable electrical motor to use as an electric banding wheel while glazing. Somehow it needs to survive contact with water/glaze or be entirely isolated from it. Anyone have experience with building something like this? Thanks

Full Shelves or Half Shelves in Electric Kilns
HenryBurlingame replied to HenryBurlingame's topic in Equipment Use and Repair
Sounds like it would be best to put the half shelves at the bottom (so six posts down there), and the full shelves at the top if it is level or you didn’t stagger the half shelves (which is why I assume more people put the full shelves at the bottom). Would be easy to align 3 posts of the full shelf so they are directly over 3 of the 6 posts underneath. -
Cone 10 Cobalt Blue w/o Soda Firing
Mark C. replied to sommerjono's topic in Clay and Glaze Chemistry
This looks more like a salt pot to me than soda. if its soda its a lot of soda -
The problem for me is when mixing chrome-tin pinks for my students. I have 7 and 10 gallon buckets in my studio, which means anywhere from 1.3-2 pounds per bucket and that gets expensive pretty fast even with just two colors. If it was just for me I wouldn't care at all. It would take a lot for me to consider a glaze to be too expensive for my own work.

Full Shelves or Half Shelves in Electric Kilns
neilestrick replied to HenryBurlingame's topic in Equipment Use and Repair
The posts must align vertically all the way from the top of the kiln to the floor. The shelf may warp or crack if a post is sitting on the shelf but is not supported in the same spot below the shelf. You can usually get away with it if there's only one shelf above, or if you're putting in a quarter shelf, but I would not expect a shelf at the very bottom to carry the weight of multiple shelves above it without a post aligning underneath. You can't tripod the full shelf and then have 4 posts sitting on top of it, because only 1 post would align and the unsupported areas would carry most of the weight. - Yesterday

Or prhaps you would put stilts at the points where the half shelves stilts are to sit above this level but may cause more problems later... -

Full Shelves or Half Shelves in Electric Kilns
neilestrick replied to HenryBurlingame's topic in Equipment Use and Repair
You have to use 4 posts under the full shelf so they line up with the half shelf posts. This is the problem. With 4 posts there's a good chance the shelf will rock, leaving one post not making contact and putting a lot of stress on the shelf there, resulting in cracking or warping. I really don't understand using a full shelf on the bottom and the rest half, but it's the way many people think it should be done. There's no benefit to having a full shelf on the bottom. -

How are you stilting the full bottom ahelf given the half shelves will need different positioning? -
Full Shelves or Half Shelves in Electric Kilns
Denice replied to HenryBurlingame's topic in Equipment Use and Repair
Henry I am not sure the Corelites will break in half like the standard shelves, They have a grid pattern on the underside. Is there anyone who owns a kiln near you or a pottery class, you could help someone load and fire. I have a degree in ceramics but I will take a evening pottery class when they have a teacher I want to learn from. They are always happy to have help loading, firing and unloading. Denice

Hi all, any and all questions posted by me will be related to an ongoing research I am currently conducting on the possible applications of biophilic design in creating sound generating pottery. I came across a captivating story on ancient sounds being recorded on pottery only to realize that it was all a hoax. Anyway, it led me to exploring other ways in which we could probably include mechanisms that could create sound through clay/ceramics/pottery. I am exploring an indirect implication of biophilic or natural elements such as the imitation of the sound of wind, water, bird sounds etc. through pottery all while figuring out if there is a niche for this.· 0 replies
It would be extremely great if I get responses and any help of the sort would be very much appreciated. Thanks!
