  1. Dead Field Mice In My Slip...

    i feel like it might change the chemical make up. due to the fact that Sodium chloride is a flux so i do not understand why Sodium hypochlorite( bleach) would not be a flux.
  2. Underglaze Under Clear Glaze

    not true, read my previous posts in this thread. yes, i did. but are there not many reasons for why pinholing may occur?
  3. Lusters

    Hello Sweeping statements like the one you have just offered as an answer to a question do little to advance knowledge. Granted lustres are toxic but then so are many other things that we use in daily life. Just check out your cleaning products that are in common use. Prolonged exposure to clay dust causes silicosis and fumes from the kiln are harmful to your health. Does that mean we should all stop using clay? Scaremongering like this has led to the demise of ceramic education as glazes can no longer be mixed in educational institutions. Perhaps in time we will all have to use self hardening clay as kilns will no longer be allowed to be used. Arming yourself with reliable information is the key. Knowledge is all powerful. For an informed view on H&S for lustre and overglaze refer to http://overglaze.info/?page_id=283 as well as http://overglaze.info/?page_id=525 for "Working with resinate lustres" I understand the dangersof working with clay. No I am not saying we should stop working with it alltogether. I am saying that one should take precautions in working withit. Sweeping statements likethe one you have just offered as an answer to a question do little to advanceknowledge: I was trying to state my thought on this topic in the easiestpossible manner. Personally I feel that there are other ways of getting abeautiful looking ceramic work rather then turning to luster glazes. This isthe same idea with the issue with barium glazes. Artists have found a new anddifferent way to make a safer glaze using spodumene. Granted luster’s aretoxic but then so are many other things that we use in daily life Just checkout your cleaning products that are in common use: I am in agreement to thisstatement but as I stated before I feel like there are other ways of making abeautiful piece of pottery that may be less toxic especially when it is someonewho is just starting out in ceramics and maybe is unable to take the proper precautionsto insure their safety. Prolonged exposure toclay dust causes silicosis and fumes from the kiln are harmful to your health: Iknow the dangers of silicosis. There are many ways of prolonging the effects ofit. For instance proper ventilation, wearing the proper type of mask whenmixing clay or glazes, not trimming your pieces when they are bone dry the listgoes on. Does thatmean we should all stop using clay: I am not saying we should “stop†using clayI am saying that you should have the proper safety knowledge before you decideto delve into such a dangerous endeavor. Also I think there are other ways ofgetting a similar result that one would want. Scaremongeringlike this has led to the demise of ceramic education as glazes can no longer bemixed in educational institutions: (talk about blanket statements) no it is not“scaremongering†it is the institutions that are not taking the proper precautionsand educating their students about proper safety that is making clay andglazing making less prominent. Also schools are cutting budgets for art off allkinds. It is not I or anyone else who is worried about others safety that isdecreasing ceramic education. Perhaps in time we willall have to use self hardening clay as kilns will no longer be allowed to beused: Arming yourself with reliable information is thekey. Knowledge is all powerful: thank you for these wonderful tools Iam not saying that I know everything about ceramics because I am learning somethingnew everyday but I do work in a top college level studio and I do know “somethingâ€about what I am talking about. This is how I feel about this matter and that iswhy I am putting my two since into this topic Thank you,
  4. Recycling Clay

    hi keith, i am a college student currently studying this very issue in my clay and glaze formulation class. the best way to make or reclaim clay is to blundge it. so you will need to invest in a jiffy mixer(http://www.jiffymixer.com/index.php?page=shop.browse&category_id=5&option=com_virtuemart&Itemid=1). first i would try to add some warm water into a 5 gallon bucket and keep it and keep it covered for approx. 1-4 weeks depending on the firmness of the clay. then check on it try to brake it up with a jiffy mixer. i would let it settle down again scrape the excess water off and make it into slip. i would then lay the slip on an absorbent surface such as dry plaster( just be careful not to get any plaster that is basically like clay death) then you can re wedge put it in your pugmill and use it again same idea as reclaiming. the reason why this works is that it is bring all the molecules together in making it tight and flexible rather then the way that the pugmill works where it is tearing the molecules apart. mackenzie
  5. Reclaiming Clay

    the thing that one must be apprehensive of when mixing two clay bodies is that there are different kinds of kaolins and fluxes in each clay body. a small amount of different clay will not make a difference but over a long time it will also if you mix 1/2 and 1/2 you may have molecular issues or maybe lowering the melting point or worse.
  6. Slip Rock

    i would try to add some warm water too it and keep it covered for approx a month. then check on it try to brake it up with a jiffy mixer. i would let it settle down again scrape the excess water off and make it into slip. i would then lay the slip on an absorbant surface such as dry plaster( just be careful not to get any plaster that is basically like clay death) then you can rewedge and use it again same idea as reclaiming.
  7. Lusters

    lusters are probably the worst thing you can do to yourself. they are highly toxic and can cause you cancer or worse. personally i would stere clear and toss them. if you are interested in metallic such as the luster gives you i would say investigate raku or another fun way of firing crystallines.

  9. Underglaze Under Clear Glaze

    pinholling normally occurs when a glaze is too think and or the clay body is releasing gas maybe try a longer hold on your kiln at the glazes maturation point. then for the cooling i would cool it slow.
  10. Which Mesh Silica

    yes def go with the fine silica just make sure you are ordering silica not silica sand.
  11. Mid Range Clay, Low Fire Glaze

    you can always fire a high fire clay body at a lower temp. but you can never fire a low fire temp clay higher due to the fact of melting. normally the one thing you should worry about is that you should really formulate the clay and the glaze at the same temp to reduce the risks of crazing but it should not be too worrisome. i have fired a cone 10 stoneware clay body with a cone 04-06 amaco glaze and it came out beautifully. personally i would not bisque at a higher temp due to the fact that the higher you bisque at the less porous the clay body will be so the less glaze the clay will be absorbing.
  12. Dead Field Mice In My Slip...

    personally i would not pour bleach in there due to the fact that it may change the chemical makeup of the clay. you may have some structual problems with the clay or force the clay to melt at a lower point. if it is such a big problem i would just throw away the slip and start fresh. maybe get a large garbage bucket and start reclaimeing your own clay. i reclaim my own clay and i put a metal screen (aprox like a 10 mesh maybe larger) over it so that way i can just pour my slop in there after i throw let it settle and skim of the top of the water. field mice should not be able to get through that.
  13. What Cone To Fire Bisque At?

    normally when i am bisquing my pieces i do it at a lower temp. due to the fact that the clay is more porous when fired lower, so when i am glazing the piece is more absorbent. i use a cone 10 clay body called bmix by Laguna. and i normally bisque my clay at 1700 degrees.
