  1. Left- zinc added to base clear glaze. Right- clear base. Fired to cone 3 in oxidation. Zinc reacted to hematite, magnetite, and iron disulfide bodies.
  2. From the album: Clay Tests

  3. Johnny: yes, that is part of the equation. Several other parameters I am going to test as well. Glaze interaction with iron is on the table currently.
  4. 1. Hematite. 2. Pure clay( no additions) hematite. 3. Hematite with 3% TiO2 added. 4. Magnetite 5 Newman Red. 6. Red Art. All samples fired in oxidtion.
  5. Turned out well. Think you are ready to market. Good color development.
  6. Turned out well. Good color blend, crystal development is good. I see you are playing with growth rings. Good job.
  7. TY Min. A couple of Doctors in the States have said they do not work. However, States, Counties, and hospitals have been asking the public to bring these masks in if they have them. To my knowledge, the mask worn in hospitals are N95, unless they are using the full level 4 bio suits. Certainly some mixed messages State side.
  8. Like Roberta: my wife and I live on acreage- surrounded by more timber and farmland. Very thankful we do not live in a dense urban area. I retired from home building almost 2 years ago, I still do high end finish work for high end contractor friends. I work alone mostly, rarely deal with people face to face: and have work for several more months. I am fully aware of my fortunate situation: so my concerns are for others who will be hurt by the uncertainty of these times. My mother is 87; my brother has her for a month, then my sister for a month: then me. She will stay with one of us until this storm passes. On the bright side: many potters have masks or respirators if those needs arise.
  9. Great color combinations. Population is proportional. Growth rings with featuring- good work.
  10. Predicting color break in relation to anticipated glaze run is a science of its own.
  11. Population is right- niece piece.
  12. I started out of the gate making and firing crystalline glaze: which also meant making my own glaze. From there it naturally evolved into making my own glazes; including my own versions of temmoku and others. The first ton of clay I purchased, then started making my own- later buying a pugmill. Currently, I use R2 porcelain that I specifically developed to promote crystalline growth. I make my own suspender and brushing medium: that Britt named glaze jelly. Made my own tile setters, and other kiln furniture. I prefer to explore and learn. T
  13. Marcia: Speaking of crystalline glaze- I read a thesis paper on crystalline glaze written by a student at SIU-C in 1973. As a historical perspective: 1973 was 25 years before any formal books on crystalline glaze was published ( Macro Crystalline Glaze by Peter Isley) I have read it several times: the insights and theorem are well within the boundaries of modern crystalline chemistry. The author of this thesis paper was YOU. T
  14. A recent thread on culture made me think about periods of art history. Being an arm chair historian, I often go through the history of potters before us: Adelaide Robineau's Scarab Vase comes to mind. Historians put art (including pottery) into periods: Medievel, Renaissance, Baroque, and Neo-Classical for instance. (Google "periods in art history"- you will find them) Each period in recent history lasted 100-200 years: the current period began in 1800. So if periods last 200 years, that would mean beginning in 2000, a new period should have begun.....but it has not! Qotw : what name would you ascribe to the current period of art history that began in 2000?
  15. Controlling the rate of drying has been on my agenda for a few years now. Couple of years back I was mixing a wetting agent into porcelain in an attempt to control it: those who got samples know how badly that flopped. so I have been working on a spritz made mostly of organic/food safe materials. To date, I have extended drying time by roughly 30%. When I get up to 50% or so, I will unveil it. However, I have no laboratory rats to test toxicity on, so PM me if you want to volunteer to drink a cup or two. ( that was Westerner joke by the way). T
  16. Been following this topic, but I know just enough about Japenese/Chinese/Korean culture to say something wrong. One of the many times I wish Baymore was around: these cultures were his speciality. Being a Westerner, I will add a twist to it. Modern technology has managed to put most of the worlds population onto a single stage/platform. The assimilation of culture that once took centuries, now only requires a mouse click. Marco Polo bought back porcelain pieces from China: and Europe spent 500 years trying to replicate them. Any potter can click Sung/Ming dynasty and start throwing in an attempt to duplicate it. The unfortunate side effect of instant knowledge, is the loss of culture and application. The old saying goes "imitation is the sincerest form of flattery." Should the blog writer be offended or flattered that others are trying to imitate her culture? Obviously some have hijacked strictly for ill advised sales promotions. Yet others love the work, love the culture, and are sincerely trying to imitate it. Personally I think she should educate rather than reprove. It is a futile effort to chastise those who have no respect to begin with. thats my 5 cents worth. The extra 3 cents if for shipping and handling. Tom
