  1. I have used Helmar Kaolin directly onto clay in a dry form and as an addition to slips for wood firing. 

    I can't say it would be the same as what your local clay maker is creating because I have no idea what that is.Here are some for several firings in the past 2 years.








  2. Sorry folks, but all fours is not cutting it. I didn't think this was extremely difficult, but harder than what I have been doing of late. I does refer to some obscure minerals, and some other things, When dealing with this material sometimes it was difficult to find a distrator so sometimes a generic all or nothing is the only last choice. Remembering also that this is according to the articles in this book.


    Sorry for the difficulty,





    I think there are more options than the book refers to. If one does not have the book, than yes, it is very difficult.But still fun and educational!



    This will work in terms of a better tax deduction for you. But the person buying the platter does not get any tax deduction in this scenario. They will know that the money went to charity, which might be enough for them (or might not). If there are other artists involved, they might not all be filing Schedule Cs in order to make this work. But still it's worth discussing with the organizer. It would be nice if they gave you the option to handle it this way. 

    Thanks Mea. I hadn't thought through that the purchaser wouldn't get a tax write off in this scenario. 


    Can anyone confirm the rules on how much a purchaser is able to claim as a tax write off?  I think (but am not sure) that the buyer can claim a charitable contribution for the amount paid in excess of the retail price.  However, in the case of artwork, if the artist can only claim their materials it seems like there is an argument that the write off should be for the price the buyer paid in excess of the cost of materials.   :wacko:



     A purchaser can not deduct a donation IF they receive something for that donation such a a piece of art work or Pottery




  4. We had an annual fund raiser in Billings for the Mental Health Foundation's Drop-in Center for the Adult Mentally Challenged. May Clay Day.

    We got corporate sponsors, ads in the newspaper and wheels brought in from the University, schools and potters studios. We may have had about 40 wheels. Then abut 300 volunteers and people to help teach throwing. Clay was donated. People tried the wheel with assistance. The little kids were the most fun. Handbuilding tent was there with volunteers too. We have music, food, booths where potters sold work. We fired work and arranged for pick up two weeks later. We also had raku demos and let people glaze bisqued pieces. We planned it for at least 6 months prior..ttook place in one of the city parks. I was on the board for 8 years..until I moved. I also volunteer small workshops at the Drop-in center. Best way to success is to get the whole community behind you. Corporate sponsors is a big help for funding the basic event. Banks, newspaper, Businesses.


  5. Mark is right. The Reagan era ushered in the "materials only" deduction for artists when they donate work.

    The Art museum here has a huge auction going on 48 years. They allow the artist to keep some of the auction prices. If you get a good auctioneer, money can be made. The Archie bray live auction had a min. of $4000 for about 12 pieces.  That has taken a while to become so successful - like 60 years. Famous Board members donate their work.



  6. Doc, no girls here. Us women clean tools but us older women love coconut oil for our skin. I may try it on my tools. Montana isn't so harsh on metal like south polluted texas air was. if I left a utility knife outside overnight, it would be rusted by the next morning. The Matamoros dump may have contributed to this. Plus we use to get the smoke from the sugar cane burn off on the Yucatan Peninsula. Anyway I appreciate the idea of keeping tools primed with something to protect them...


    no girl, 68 plus counting

    cleaned my throwing tools as I cleaned my studio in prep for the 600 pounds of porcelain I re-pugged and de aired. Threw some tonight and it was a pleasure!


    The lead traditionally turns the white slip decoration yellow in earthenware. When I lived in Spain and they joined the EU in 1986 I was under the impression that lead was forbidden.


    I don't believe that lead in itself turns white slip decoration yellow. Certainly, I have used clear glazes formulated with lead bisilicate over white slips, and no yellowing was evident. I suspect that any historical yellowing was caused by impurities in the lead used at the time (often just dusted on, or crudely washed in place), or deliberately caused by the addition of iron, as in my example.

    Lead frits are widely available across Europe, although this position may change, as the law begins to codify information regarding lead as an endocrine disruptor (on top of everything else).

    Industry continues to use lead in glazes, of cours

    It may be determined more by the clay. I have seen yellow lead/iron glazes as well as green lead/copper and brown lead/managsese  on the low fire clays in Spain. 

  8. Here is the article I think Marcia is referring to. It is a good one I book marked it a few years ago when I came across it:




    I am not sure if it is the same article as in the magazine, but this one is a nice read although mostly unrelated to the actual glaze. The end result is near the bottom if your just looking for a recipe to try.

    Yes , that's the one. Not typical for Jeff's type of article. But I liked it.

    And it gives directions for using the bone ash which is a flux.


  9. From what I know and what I can remember,: cremated remains are basically bone ash. Jeff Zamek is a ceramics consultant and in 2001 his dog , Zeke ,I think, died. He was cremated and Jeff kept the ashes around for a while. He worte a touching article for Ceramics monthly, Black Friday. 

    If you google Jeff amen you'll find a long list of publications on technical items and the "other topics" . Black friday is the article you need.  If you are near a good University Library with ceramics Monthly, you could find it. May 2001. Otherwise, you can order reprints of articles from Jeff for $6.50


    I gave all my issues away when I moved. The archives should be available is tyou have an online subscription upgrade. But they are only at the first phase of the transition to the new website.

    1. cm-mobile Archives - Page 10 of 59 - Ceramics Monthly

      Guilford Center's Ceramics 2001. Medalta: ... Ceramics Monthly May 2001May 1, ... Black Friday by Jeff Zamack. <-incorrect spelling in this notation.



      Otherwise, look up recipes using natural bone ash.
