    Red Mid-high fire range clay body

    here is my former teacher's (Bill Daley) clay body. He fired it at a brick yard conveyor kiln. Daley's is toasty golden, Linda's is rich and deeper color, and David's is the reddest. If you search the Ceramics monthly Archives for an article with Daley and Wright you could see examples of their pieces. Daley's and Linda's are more for hand building. Wright's can be thrown. I just noticed the above link has examples of Daley's clay body.

    Copper spot effect

    I have used very fine silicon carbide to achieve copper reds in ^10 oxidation without much spotting. If you want the copper spotting as on the first pot, you might try copper granules and fire the pot in a saggar for the glaze firing and include some charcoal briquets, Someone was discussing saggars in reduction on here in the past year or so.

    Age of dry materials

    I had a friend receive a large quantity of chemicals from a family of a deceased potter. It was going to cost the family about $10,000 to throw away the chemicals which would have to be tested for toxic disposal. You might explain that to the family when you make your offer. That is a lot of good chemicals some of which are extinct. I'd like to suggest to old potters out there to consider leaving your studio chemicals to someone so the family doesn't have to deal with disposal costs. There are lucky to find Roberta.

    Lots of questions about soda firing!!!

    Building a catenary arch support isn't difficult. Figure the size you need ( base it around the shelf size you'll be using). Get a chain , mark the dimensions height and width and nail the chain to reach those dimensions. Spray paint 3 pieces of plywood. cut it out with a jigsaw. Build it well. install on site raised on shims that afterwards it will drop the form and slide it out of the form. Marcia

    Lots of questions about soda firing!!!

    I built a castable one like the catenary in Ruthanne's book. I have also fired with her. She sprays in dissolved soda ash. I would recommend learning to fire a kiln and the go to soda. Firing soda has more temperature fluctuation in between applying soda into the kiln. We fired the soft brick kiln at La Meridiana back in 2000. That kiln lasted over a decade. They must have been high alumina soft bricks. They have rebuilt a new one again with soft insulating bricks. Marcia
  9. I couldn't even FIND my gallery until DH send me a link. Someone else said click on my avatar which I have difficulty finding as well. When did the "update " the format. Mine opens to the members gallery then I have to go to the forum.

    finally got to my gallery Here is a cobalt green glaze , recipe in the comments Marcia
  11. I got a warning that I am almost out of space in my members gallery. I would like to delete old images. I can't even find my gallery. Could someone give me directions? I was going to post an image of a cobalt green glaze in response to a forum question. I also have posted the recipe in the gallery. I could not find it. It is in my album "Forum Discussions" but could not find it. Marcia

    recent soluble salts firing in saggars

    I can get several smaller saggars in my raku oil drum kiln. My new topcoat pulley kiln will hold a lot more. the interior is 31.5 x 27. .5 and 29 ht. This is the chamber for the pulleys. -upside down.

    are there any green food safe glazes

    I use a cobalt green glaze. I have used it on dinnerware. There is a photo of it on my gallery under the album Forum discussions. The recipe is there too. I am not navigating the new format well or I would give you a link. Recipe is from Michael Bailey's book. Cone 6 Oxidation.

    OM4 Ball Clay and soluble salts

    the barium is used to prevent scumming of the soluble salts migrating to the surfaces. It is a common additive to earthenware clay bodies. Most majolica painters I know who mix their own clay add this...or use to. Marcia
