  1. I think I will stick to stoneware. I just checked the shrinkage values of porcelains vs my G mix/6.. Porcelain shrinks a lot less so my glaze would not fit. At this stage, I am not going to go through the ritual of modifying my glazes.
  2. My problem in trying various porcelains is where I live, Spokane Washington. There are no major suppliers here and shipping, particularly small amounts, of clay is quite ridiculous. It can easily cost more than the clay itself. Being the cheapie I am, that is a consideration. Some people think I'm so tight, I squeaked when I walk.
  3. I will give porcelain a try....since i am an experimenter at heart. Once I successfully make something, I rarely make another. It is more fun to stretch my skills in another direction.
  4. Such oversimplification of the mere structure is not as helpful as I thought you would be. I was hoping for a more in depth discussion of how rapid quantum phase changes cause quantum mechanical wave-interferences with the van der Waals force
  5. This is mostly redundant to the above post since this forum will not let me edit the above post ------ Hey dude, I want the full chemistry lesson. No shortcuts allowed. Glazenerd does mix and sell a fancy porcelain. I have tried a little of it. From a beginners point of view, it seems to throw easily. However, I , as a beginner have no comparison to any other porcelain . A beginner would think that white stoneware is white because it has very little iron to leach???

  7. If you like both porcelain and black clay, US pigment has a black porcelain that is supposed to be pretty good. My throwing skills are descent. I guess I need a porcelain clay sample kit to try out several to see what works best :). I have used white stoneware almost exclusively because it seemed like a bad for a beginner to add the extra variable of different clays to the complexity of different glazes. I did try some white porcelain that Glazenerd sent me. It did seem to throw pretty easily. And yes, I have also had cracking problems with white stoneware. I did not realize that white stoneware was more prone to that. Since I throw completely dry, the extra water absorption of porcelain would not be a problem. .... I think the above is taking to myself to talk myself into switching to porcelain.... Thanks all for providing me with the grist to chew on.
  8. "I ended up being confused as for why anyone would use a white stoneware.".... please expand on this. On test tiles tiles I have gotten porcelain clay to stick very well to white stoneware bisque and through firing. The porcelain coating makes both bisque and glaze fire clay slightly whiter. However, there is no color difference between favorite glazes like Selsor Oribe and Copper Red w/Silicon Carbide between that applied directly to the stoneware vs over the porcelain layer. From what I understand, I should get brighter colors over the porcelain. I don't get it???
  9. I have only used white stoneware at ^6 but I am thinking about trying porcelain. From what I understand porcelain is like throwing cream cheese. ... which sounds hard. However, from what little I know about such things, I would think that a thin coat of porcelain over white stoneware would give the same look but would be much easier to large pots with. What am I missing here???
  10. majolica line shrinking to dashed line

    Good point. I will try that too.
  11. majolica line shrinking to dashed line

    both, and it often works.
  12. majolica line shrinking to dashed line

    I am sure you are right, but , but , but, often I am putting it on thick to get a 3d effect.
  13. majolica line shrinking to dashed line

    I am squeezing out a glaze formulated for majolica. San Diego State U Majolica - C 6 Dolomite 2.3 Whiting 8.7 Feldspar 35.8 EPK 5.8 Flint 35.7 frit 3124 10.5 Zircopax 1 Bentonite 2 Epsom salts 0.6
  14. With my squeeze bottle I can make nice continuous lines, until they dry and crack into dashed lines.. I don't see that problem with others work. How fo I fix this? I am usually working on ^6 bisque
