      Moderators needed!   12/08/2017

      Ceramic Arts Network is looking for two new forum moderators for the Clay and Glaze Chemistry and Equipment Use and Repair sections of the Ceramic Arts Network Community Forum. We are looking for somebody who is an active participant (i.e. somebody who participates on a daily basis, or near daily) on the forum. Moderators must be willing to monitor the forum on a daily basis to remove spam, make sure members are adhering to the Forum Terms of Use, and make sure posts are in the appropriate categories. In addition to moderating their primary sections, Moderators must work as a team with other moderators to monitor the areas of the forum that do not have dedicated moderators (Educational Approaches and Resources, Aesthetic Approaches and Philosophy, etc.). Moderators must have a solid understanding of the area of the forum they are going to moderate (i.e. the Clay and Glaze Chemistry moderator must be somebody who mixes, tests, and has a decent understanding of materials). Moderators must be diplomatic communicators, be receptive to others’ ideas, and be able to see things from multiple perspectives. This is a volunteer position that comes with an honorary annual ICAN Gold membership. If you are interested, please send an email outlining your experience and qualifications to jharnetty@ceramics.org.

  1. Hi peps, Does anyone know if your can burn of decals I have a bowl on which the decal bubbled and it was also lost because of the colour. The glaze firing was to 1260 C for your information. Thanks in advance

    No, I bisque first then airbrush, fire to bisque. Next comes the glaze (transparent). The decals are placed and fired to glaze temp. The luster is applied and fired tp 800 deg C. so in total 5 firings. The decal is a local South African plant called Stralitzia. Image attached. So happy with the response from everyone.

    Yes they are called Stralitzia
  6. Air Brushed Pieces

    My first attempt at using a spray gun for the underglaze and the final glaze. All fired to 1260 C. Stoneware and Porcelain
  7. I thought that the sand being silca would melt onto the ware, creating unwanted jagged bits on the bottom
  8. Hi, I thought I'd let you all know that I re-fired and the pin holes healed. So it loos like the problem was the interruption of electricity during the original fireing. As always, many thanks for your input. Regards Andrea
  9. Spray Glazing Vs Dipping

    [ I don't get the grams per sq inch! Could you please explain? I wasn't able to spray the glaze due to a compressor malfunction -- HaHa and I ended up by dipping (see my post on pin holes) and ended up with only two small pieces with out any pin holes. I also had an electricity outage during the glaze fire. Multiple issues in one fireing. However the sprayed underglaze gave me some nice results. attachment=8827:18767635_1851325515193512_8695764048092189375_n.jpg]
  10. I must add to my original post that the pin holes are very small and appear larger in the pic because I enlarged the image The compressor packed up when it came to do the glazing. It had run out of oil! This clear glaze seemed to be the right thickness. Don't have a hydrometer (will be making one a.s.a.p) so I use the hand method. In this case the pin holes are very small so it wouldn't be practical to fill them and re-fire. Although I think I'll do a re-fire to smooth out the glaze. Thoughts? Thanks for the feedback, as always it's much appreciated. Andrea
  11. Good morning all, Following in from a previous post where I asked about spraying glaze vs dipping. Just unloaded the kiln and found small pinholes in every piece. Here's the process. Sprayed underglaze Bisque fired to 1000 Deg C Approx 20min soak at 1000 Bisque sponged and dipped into water, allowed to dry Dipped glaze (all transparent from same bucket) Fired to cone 8. Loss of electricity for approx 45 mins at 800 deg with a resulting drop to 500 deg Hubby's theory is that there was a case of oil spitting during the underglaze spraying resulting in small oil drop absorption. If that was the case wouldn't the bisque fire burn off the oil? Would re-fireing help to smooth out the glaze?
  12. Spray Glazing Vs Dipping

    Thanks Marcia, I found Stephen's article on spraying and it will help a lot. As oldlady says this is going to be a journey, but I think it will be well worth it. Having sprayed instead of brushing the underglaze I love the blended results and I can't see that dipping will enhance them. As I said I don't do well with dipping. The little jug has been dipped, cleaned off, retried a number of times. I'll post pics of the finished work. Have a great week. Andrea
  13. Hi everyone, Hope you all have had a great weekend. I'm a messy glazer with drips everywhere and have had to redo the process on more than one occasion. I've just had a wonderful result from spraying underglaze onto my work and I'd really like to have a perfect finish. My questions are: Is it better to spray or to dip? If spraying, how many coats do I give the ware? Pics of the bisque below. Thanks in advance for your thoughts Andrea
  14. Sake Set

    Hi everybody, Some help please. I've got an exhibition coming up and I want to enter with a sake set. The exhibition is entitled "Pour". My problem is I've never used or even seen a sake set, so I have no idea what size to make the cups. What's your opinion regarding size, shape, with foot ring or without? Here is the jug I've thrown Any suggestions would be much appreciated. Have a good day. Andrea
