    Speedball bought the Clay Boss line but not the HP, MP and Jr wheels that proceeded them. There is no vender support for the HP, MP, Jr.
  3. Opps--thanks Neil-I need to be more careful with terminology---luster-like , crystalline-like, shino-like etc. are not the same as the correctly formulated products or processes. Great example as to why I rarely offer technical info LOL.
  4. Thank you, Neilestrick! Your post has been very helpful!

    Thanks Mark i had it all wrong, I thought that the last fast firing had fired out the oxides, that's why there was no colour. Thanks for the explanation. Maggie

    Glazes respond to time and temperature .Not just a set point like cone 6 end point That said a cone 6 at 5 hours will look a lot different than a cone 6 at 9 hours. The glaze has no maturing time in a fast fire. You just found the out with your fast fire.

    Thanks Neil, That makes sense. I will go back to the slow glaze! Thanks, Maggie

    Instead of wrapping I favor the sheet metal shield. The pipe will not corrode that way and its all out in the open for inspection. The other suggestion is painting the pipes with high heat silver paint-comes in a spray can is aluminum colored and really reflects heat well. It holds up super well to high heat situtaions.I spray all my gas lines close to kilns with it. Hensells hardware sells it in paint Dept. I also spray all my kiln metal work with it before the rust sets in.It protects for decades.

    three comments: 1. The updraft gas kilns at the local college have similar burner and piping arrangements as being used here and have shown no evidence of being overheated in the 12+ years I have observed them. The piping has only the galvanized and paint coatings from the manufacturer. The kilns are fired 1 to 2 times per week during the three semesters each year. 2. If you wrap the piping, be sure you thoroughly inspect the piping and structural members for corrosion prior to each firing. Piping in an environment with high humidity and an insulating covering will be subject to hidden pitting corrosion underneath the insulating material; the risk is especially increased when the piping is only heated periodically. 3. Consider the effects of wind blowing across the kiln area floor and interfering with the burners and pilots. You might need to add some portable windbreakers. Even though the college kilns are in a large shed with half walls on three sides (full wall on one), high wind conditions have shut down the kilns by blowing out the burners/pilots. Portable wind breaks are used to mitigate the winds. LT
  12. Thank you! I think this is more what I was looking for, although oil spot glazes are amazing, I'm not quite on that level yet.

    bw- You might also consider mounting a poece of metal flashing about an inch + from the gas line. You could put a bend in it so that it shields the gas line from both the burner and the kiln floor. Regards, Fred
  14. I believe you may find as Neil says that many of the parts are standard. If I remember correctly, the HP and MP wheel that I had at the HS used auto V belts. The HP wheel was built quite well, as was the MP even if under powered for me. Not much should wear out on them. best, Pres

    Lots of glazes don't respond well to fast firings. It's not only that they're not spending as long in the kiln, but also that the kiln is going to cool a little fast since the bricks haven't had as long to absorb heat. I would go back to a slower firing. If the cone offset is correct, it should be correct at either speed.

    Yep, talk to speedball. However, the thing with wheels is that the parts that would need to be replaced- electronics, belts, motors, most bearings, etc., are not specific to wheels. They are standard parts that can be found elsewhere.

    Thanks Johnny, I was hoping to hear that. I love this glaze and hate to lose it! Maggie

    Hi Maggie, welcome to the Forums...The fast firing could be the problem...not enough heatwork time to let the glazes to develop properly. You might try again, refiring the pieces with a 20 minute hold at the end, or go back to your original firing schedule with the 35 degree offset and see what happens. JohnnyK

    Yes, I had cones in - I have attached the files.... perfect 6. Glaze didn't run more than usual (actually, it was a great firing except for the fact that the colour was burned out). No pinholes, blisters etc. The glaze is the same one that I always use - no change in the application.

    Did you have cones in to verify it reached cone 6 and didn’t fire hotter? Did your glazes run more than usual? Pinholes, blisters? Change in glaze application? If you would post a picture of your pots that might help too. Welcome to the forum!

    Speedball bought them out and parts for the older models will be hard to find-you can call them and ask about this. They make the newer clay boss models now.
  23. Do I understand correctly that all creative industries wheels are no longer supported at all--meaning that parts (belts etc. ) for them cannot be found? Would this mean you would have a wheel you could no longer repair or make work at optimal speeds?

    Neil- that was a concern for us as well, but there is actually about inches between them. We're going to wrap about 18" of it with kaowool just in case.

    Fast Firing

    I need help. I replaced all my elements, thermocouple, etc as I have been having terrible firings. I contacted my Kiln controller provider (Bartlett)as my kiln is firing 35 degrees lower than it should be. He suggested that I lower my the Cone Offset to 9010 and fire my glaze firing to fast glaze. It fired approximately 5 hours (Usually it fires for 7 hours). It reached the proper cone 6 but all my glazes (which are cone 6 glazes) are washed out - the colour is not there. Does anyone have any suggestions. Maggie P.S. The cone was a perfect 6 ....(7) wasn't even starting to bend. The plate in the picture is the colour that I usually get - nice blue. The mug is all washed out (it looks like the oxides have been burned out).

    In that last photo- I'm not a fan of how close to the burner that gas line is. There's a lot of radiant heat that comes out around that burner port. You would be better off bringing it in from the front of your concrete riser.

    Engobe for decorative use on bisque

    Liz, There is a term for underglaze, where the glaze is applied over a decorating/coloring material that has been applied before glazing. Then there is a technique of applying the decorating/coloring material over the glaze known in most circles as in-glaze. Both methods will achieve similar, but dissimilar results. Also, when doing in-glaze the decorating/coloring material us usually thinner as if too thick on the surface of the glaze will be rough after firing. Experimentation on test pieces will always allow you to understand your processes and allow you to adjust your materials for the type of technique you are doing. best, Pres
