11 <db:para><db:date>2007-10-29</db:date> White was not fully dry when dipping. Yellow was brushed on top before firing. Doesn't work at all, it physically moves the underlying glaze and is unpredictable. Even though there was an overlap between the white and black, it doesnt' create any visible problems, which is a bit thought provoking when compared to the damage seen on piece 37. Seems as if the black overlapped the white. As long as the overlap is small, it is ok?</db:para>

19 <db:para><db:date>2007-10-29</db:date> Both glazes are very thick as the gravity numbers reveals, and they appear thick too. Especially the white, it has characteristic dots. The white was across the whole. The white was still wet/cold, when dipping the black. Black on top of white doesn't work at all. I can't recall the crack on the edge before bisque firing, so it probably appeared in glaze firing. The white was glazed uneven, as can be seen on the inside. Dropped it in the floor while photofgraphing.</db:para>

26 <db:para><db:date>2007-10-29</db:date> The edge is a bit rough, partly due to lack of glaze. Apart from careful handling when loading the oven, maybe it would be of help to slightly dip the edge only, once the first full dip has dried. Depends on how strong difference in thickness shows, which I suspect is very little. Shows well off the glaze. The yellow brush on glaze was dripped on before glaze firing.</db:para>

99 <db:para><db:date>2007-12-02</db:date> With tape, permanent wax and Mask&Peel wax, the two halfs of white and black were painted out. First the black outside, then the black inside, the white inside, white outside. Time consuming, error prone process. Wouldn't surprise me if the white or black comes out contaminated. The black outside was double glazed, though it had pin holes both before and after. The white outside was glazed three times(although without full drying inbetween) in order to try to tackle pinholes. The white inside was done by filling up(yes, on top of the black with wax on top) and rolling around three times. The top edge became very thick and uneven at the end. Hard to find a masking mechanism that sticks on top of glaze.</db:para>

108 <db:para><db:date>2007-12-16</db:date> Glazed the whole in Frosted Jade first. This went quite well, I had such a large quantity that I simply filled up the whole inside up to the rim. After, strips with "stamp"-tape that was activated with water was applied to form the T. A sewing-strip was used to ensure the tape was somewhat centered in the middle.</db:para>
110 <db:para>Once done, the whole thing was waxed with permanent wax, the strips removed, and glazed with Green Hue. I think glue from the strips sticked to the glaze(or was it water, or had the wax flown in beneath? Doubt the latter), so it will be interesting to see how Green Hue will deal with that. Green Hue was extremely thick. Like an old man in acid.</db:para>
112 <db:para>As usual this was messy, due to the strips pulling off the wax a bit(had to repair by hand with brush), glaze staying on top of the wax(had to wipe off). Both glaze batches had been extend and therefore remixed/sieved and were creamy and ran easy. Have no clue how this will turn out.</db:para>
114 <db:para><db:date>2007-12-22-20</db:date> Issues: tons of blister in Frosted Jade, Green Hue not gripping at the very bottom on the outside. Slight orange skin on the Green Hue here and there, perhaps caused by thickness. Beyond the problems the general idea works and it looks ok.</db:para>
116 <db:para>On the outside there's a strange shift towards black at the bottom, looks like at the area where it was trimmed. Coarser surface, stronger oxidation?</db:para>

125 <db:para><db:date>2007-12-16</db:date> Did the ring on the inside with guidelines on the inside by an ink pen, followed by filling in with the black. All the others were done with tape masking. The angles and straight lines were generally tricky, a Linex template was often of good help for putting a first baseline. Many angles are out of order and it's generally a bit sloppy. Leakage on many places, especially the long inside strip, due to that the tape has to be so darn tight. Quite time consuming, time is no 01:30.</db:para>
127 <db:para>Afterwards the whole thing was glazed with green, which was creamy but thick. Poored on the inside and tilted around. Poored twice on the outside, if I recall correctly. Managed to drop the thing in the 65 L bucket, which explains any uneveness on the outside. The rim, as often, was rather uneven due to dripping and so on.</db:para>
129 <db:para><db:date>2007-12-22-20</db:date> Issues: just as <db:xref xlink:href="#P33"/> and <db:xref xlink:href="#P40"/> orange skin can be seen. If this isn't glaze thickness(which is thick) I suspect kiln contamination that turned the crap into a salt firing. At times uneven on the outside and it should have been thicker, it should have been as the inside is, a healty strong green. Pin holes here and there. At some places the underglazes was pulled away causing small artifacts. Maybe this could have been avoided by ensuring it's not a thick layer of underglaze. No, Potterycrafts LTD'a note on Underglaze Decoration states that an underglaze that "weeps" is caused by too high water content in the glaze on top, and this can be avoided by hardening(e.g firing) or using a spray gun to get a thin layer. That the rim was uneven after glazing didn't show that strongly when fired; a slight variation when looking from the side.</db:para>
131 <db:para>The pinholes are almost exclusively on the outside and the outside is not as thick as the inside. So, glazing the outside four times, or push up the gravity to maybe 60 could possibly solve it.</db:para>

138 <db:para><db:date>2008-06-15</db:date> Glazed the inside with white, but it went totally wrong. It wasn't sieved, so big and small chunks of glaze sat on the inside. Basically, the amount was maybe 3-4 liters, and it's insufficient to stir such an amount up with a spoon, one must sieve it. I washed out the whole thing with warm water and a dish brush. So, probably it has traces of gloss over the whole piece.</db:para>
140 <db:para><db:date>2008-06-22</db:date> Failure. What kind of focus do I lack? Work in, poop out, this is a great trade. The outside is ok, but the inside is unevenly glazed and the "cut" between the inside and the outside is doped. It should have been waxed somehow. But nevertheless this will always be difficult since copper flows into other glazes so easily. The green crazed for some reason. The rim moves towards brown/red green. Because the rim had a very thick layer of glaze, the copper was probably subject to reduction.</db:para>

First the wax went off when removing the tape, so I had to rewax without tape. I doubt waxing works with tape on, even if the overlap is very small. The black glaze was spectacularly uneven, lots of rinning going on. The cuts were added to hide edge damage caused when trimming, and the glaze patterns, acting as practice, accompanied the style.</db:para>

Then the news paper was removed. Compared to using tape, the soaked paper stick much better. The other five with stripes were done by spinning the piece on an iron whirler and apply resistive wax(P3384). The white glazed was first genly brushed with water, such that the glaze would suck less, and hence not jam/drain the wax-brush. Due to rythm, the stripes come out uneven as they did.</db:para>

I suspect the orange skin is caused by the thickness of the glaze. The glaze lack the same kind of appearance as it has on <db:xref xlink:href="#P15"/>.

262 <db:para><db:date>2007-11-22</db:date> Masking escapades. First the inside and outside was completely glazed in white. The inside went well -- easy when it's big and plenty of glaze. The outside as well. Had it standing on two rulers that sat on the edge of a bucket, which was spinning with the help of a iron whirler. Taped on the outside, on top of the white glaze. The tape won't stick on top of the glaze, but it will to itself if one goes all the way around. However, it's still not enough for creating a non-leaking edge, as the fired piece will demonstrate. Though, it helps if one has an overlapping, reinforcing layer at the opposite side of what is being masked.</db:para>
264 <db:para>Once the tape was in place, the white glaze at the top and at the passage was scraped and subsequently wiped off. Once done, the open sides was taped up a bit(but apparently not enough), and the passage glazed with black, and the top edge with one thick layer of yellow. Once the yellow was semi-dry, it was smoothed out with a watered brush.</db:para>
266 <db:para>The tape thing doesn't work at all, it can't keep the glaze away, it's too loose. Removable wax combined with tape is a no go because the tape rips off all the wax, as seen with <db:xref xlink:href="#P15"/>. However, resistive wax(P3384) sticks strongly to the glaze, and the tape doesn't pull it off with it. All in all, black ended up pretty much everywhere. Spots on the inside, rinning on the outside, and on top of the yellow. The piece needs to be completely covered up. Bags plus tape.</db:para>

Let water run on the bisqued piece first such that it absorbed plenty, in the hope that the glaze would stick better(but unfortunately less as well, but that's only as long as the first layer is wet). Glazed the inside by tilting as usual, and poored on the outside. The outside has three areas, where each area had one additional layer.</db:para>
344 <db:para>The glaze had rather large particles that trickling maybe would have solved. Maybe it will be more gray instead of green for this reason.</db:para>

418 <db:para>When contrasting to <db:xref xlink:href="#P26"/>, the conclusion is that rewedged clay breaks out more gases than new clay, and mat glazes are known for being less well at healing up. So so far Frosted Jade is not recommended for rewedged clay, I'd say. This glaze is extremely sensitive to thickness, small variations makes it throw out into graphite black. Would probably be suitable for spray gun.</db:para>

442 <db:para><db:date>2008-03-03</db:date> The orange skin is due to too thick glaze. The glaze is most likely based on some form of iron oxide, and due to all the iron it starts turning into an oil spot.</db:para>
