Yes! That's the glaze I'm having trouble with. Reduction has been the same each firing. I was hoping there was some material that would increase the melting point. Like I said, I have no knowledge of how to mix glazes or what materials do what. I tried adding silica to the glaze because Google told me that it would raise the temp, but I think it did the opposite. ;-)

Hey all,
New to trying to adjust and mess with a store bought glaze. I have a premixed Cone 10 turquoise glaze that I have used for over 15 years that I purchase from my local clay supplier, (Laguna Clay). I usually fire in a reduction to the same temp and recently the color has been burning out and running horribly. I am guessing they changed the formula but did not say anything. What can I add to the Matte glaze to raise the melting point of the glaze? Or at least stop the running?
Glazes are my weak point, whether I have been intimidated by them or just plain too lazy to really understand them. So any help would be great.

I tried connecting using the mirror feature, but it only gave me a "screen sized" image of what you see on my phone. Also the quality of the video was so bad that you could hardly see what was being shown. Going to try a couple other possibilities, but I think a video camera will be better.

I have a HUGE TV in my classroom. Think the size of a white board, 4' X 8'. I want to purchase a camera that I can connect to the TV for when I do demonstrations so that My students in the back of the room can see all the details of my demo just like the kids in the front row. Does anyone have a camera that they use in that way that they like?
Thanks in advance!

Any one use one of the small hand held protein shake mixer/ milk froth mixer for mixing low fire bottled glazes? I have a lot of bottled glazes that sit for a couple months. I add water to them and shake them like a bartender and that usually works, but was looking for an automated tool to help mix them quicker. Does one brand work better than another? Thinking it might need a bit of power if the glazes have dried out a little and are fairly firm. Thanks in advance.

I have been using an updraft kiln (Gas) for over 20 years. I will be moving to a new classroom and I get to pick a new kiln!!! ( I know exciting stuff!) They want me to go with Olympic Kilns and as I look at them, I only see gas downdraft kilns. Is there a big difference in firing a downdraft kiln vs. an updraft kiln? Are there any pros or cons? I usually fire to Cone 10 Reduction. Thanks in advance.

I have a Soldner Mixer and Peter Pugger and will be getting new kilns. But the storage shelves I have are OLD desks and boards held up by larger blocks of wood that are rotting. So I am looking for ways to store my Kiln Posts and shelves. Also , dry storage for Kiln wash and raw materials, ( EPK, Silica, Feldspar, Bentonite, Ball Clay).

@Elmoclayman, if you were asking specifically about storage of kiln furniture in your classroom situation, I think @Mark C. has posted pictures of his production studio set-up, refined over the years, that is what I’d like, ideally.
I couldn't find the post of @MarkC. pictures. Could you Sharte it?

I will be moving into a new classroom for my High School Ceramics class and will be getting mostly all new furniture and storage. (I know LUCKY me!) First time I have gotten new anything in over 20 years of teaching! They are going to buy all new furniture for me and I was able to pick out the big items like table, stools, cabinets etc... I will need to replace my Kiln Furniture storage, (Kiln Posts, Shelves, Kiln Wash), do you have a cabinet/ shelving you purchased that you like? Or did you adapt something to fit your need? Or did you just build exactly what you wanted? All things I am considering as I get ready for the big move in about 6 months.
Thanks!

I got a pile of something similar to these for my kids’ assorted drawing implements. Check the third picture to get a clear (heh) image of them. They’re a nice size that you could either build individual kits in each drawer, or they’ll fit the equivalent of 24 Sharpie markers, with room at the back (front?)of the drawer. A great size for most pottery hand tools. You’d probably want something bigger for sponges. Dollar Tree apparently sells them by the case.
These look like what I am looking for, but 5X5X1 is a little small. Most of the tools I have are a minimum of 6" long, many are 8"+

How much do they have to hold, and do you know what size space they have to fit in? Do you have a price point you want to stay within?
I need to stay as cheap as possible. I only get $900 for all materials for the year. I do beg for voluntary donations, but that seems to dwindle each year. I have seen some clear plastic 3 drawer organizers at WalMart and Target, but at $10 a piece, I would need 7 or 8 to store all the tools. I will be moving into a new classroom but I don't know what kind of storage I will have as of yet.

I teach Ceramics Classes at the High School level and will be moving to a newly renovated room sometime around December of this year. I am trying to pack up the "Stuff" I have accumulated over the 20 years I have been here and the 30+ years the teacher before me was in this room. I have collected a number of hand building tools that I keep in small trays in a cupboard, separated by size and type, (ie. loop tools of one type in one tray, wooden modeling tools in another tray). The problem is its hard to see what tools are in each tray. I am looking for a possible clear plastic drawer system that you have seen, or possibly use in your own studio or classroom. I would like to be able to see which tools are in each drawer when I open the cupboard.
Pics would be very helpful if you have anything like this. Thanks in advance!

Is the kiln 50 amps, or is it on a 50 amp breaker? Kilns must be on a breaker that is 25% greater than the draw. Either way, 50 amps on 240V 3P is under-powered by today's standards for a kiln of that size. Your kiln is approximately 18 cubic feet, and by comparison, a 16 cubic foot L&L front loader will pull 58 amps. The L&L is rated to cone 10, though, so you don't really need that much power for your situation. I think you'll have a difficult time finding a kiln of that size that will have that low a power draw, however you may be able to have the elements customized to work within your specific electrical needs.
Delivery on a kiln of that size (depending on where it ships from) could be $1000 or more, so make sure you get a shipping quote.
If you need someone to assist with setup then buy from your local ceramic supply shop if they offer that service. Generally you'll need a forklift to receive the kiln, and a pallet jack to move it into place. You'll need to check clearances through all doorways from the loading dock to the kiln room to make sure it'll fit. A lot of big kilns won't fit through standard doorways.
The Kiln is 50 amps, not sure of the breaker. Thanks for the shipping information. Didn't think about he equipment needed and the shipping cost. Good chance the kiln will be in an outdoor area, so getting through doorways shouldn't be a problem.

So I will try to make this short, but I am looking to purchase a front loading Electric kiln for my high school ceramics program. I will be moving to a new classroom across campus next winter and the old Carol Suzanne kiln is on its last legs and I don't plan on moving it to the new room. Some of you have been helping me with my thermocouple issues in a different thread and I really appreciate it.
The interior dimensions of the Carol Suzanne kin I have now are approx. 30" wide X 30"deep X 36" tall.
Spec.: 3 Phase, 50amp, 240 volt
I am assuming I will have the same electrical capabilities in my new room/ building. I am looking for a front loading kiln, mainly because I think its easier on the back rather than the top load. I will be using it mainly for bisque and low temp glaze firing, Cone 04 to mayber Cone 02 at the hottest. The Carol Suzanne kiln has been my workhorse and I usually do at least one sometimes 2 bisque firing a week when my students are being productive.
Anyone have any opinions on brand? Opinions on dealers that charge a fair price? Quick delivery and setup?
Thanks in advance!

Thanks for all the information! So I put the old thermocouple in and it is reading much lower than the actual temperature. I'm not sure of the the type of the old thermocouple. After firing, it was "orange" hot inside, but the temp reading was saying 756 degrees F. Once it cools, I will get some pictures to see if I can recalibrate for the new Thermocouple.
I did buy a new thermocouple: Alpine Thermocouple Type K 11gx12

Did you install the correct type of thermocouple? What type did you put in? What type was the old one? The controller has to be set for the correct type.
I installed the only one they had that looked remotely like the old one. But it was very different. Guessing that's the main problem here

we have some kiln experts here but they would like to see photos of the kiln and thermocouples and anything else that might be printed on the label. i have never heard of that brand name and wonder if anyone else has. the more info you give, the better the answer.
The kiln brand went out of business about 10 years ago, which is why you probably haven't heard of it. Its model number: CSE-BX-10, Serial Number:391, 50amp, 240v, 3 Phase

Hi all, I have a 1987 Carol Suzanne electric kiln that I have been babying to try and get through this school year. I recently replaced the thermocouple and the temp is reading nearly twice as hot as it should. I usually bisque to about 1800 and even when the temp readout said 2350, it wasn't even close to my bisque temp. Any suggestions?
Thanks
Trying to raise the melting point of a commercial glaze

Thanks so much for the information! I will try this in the next couple of glaze firings.
Just thought of another question. Does glaze "go bad"? I found some glaze in a tub that says Turquoise on it. I believe it to be the same Laguna Clay Turquoise. However, its been in this tub for about 20 years. (yeah, I know we never throw anything out) Could the glaze 'oxidize" or something like that? Would it change the way it fires? I haven't tried it, but it does appear to be a different dry color than the new turquoise glaze (dry in powder form).
