341 <db:para>The left corner has Lichen Green brushed on top in one thorough layer. In the middle there was a drop of water which gave a visible texture, maybe it shows up after firing. On the right was sprayed, which flooded in a bit under the tape, a fixativ. It prevents the surface from being powderish, but doesn't repell water, athough slows down suction a bit. Not that that is of any use. However, it makes handling a glazed piece with ones hands less destructive. Assuming it doesn't have an effect on after glaze burn. The fixativ was Winsor & Newton Artists' Fixativ, transparent, non removable.</db:para>

456 <db:para>
457 <db:date>2008-02-23</db:date> It's sort of obvious why this turned out as it did. Zinc oxide is a flux, since it's absent the thing didn't melt, and since Tin Oxide is an opacifier, it isn't transparent. I wonder what caused the graphite-look which can be seen on the second and third layer, and a little bit on the first.</db:para>
458 <db:para>
459 <db:date>2008-03-09</db:date> Crawling. Could possibly caused by be the Tin oxide, since it has a high contaction rate. Yes, John Britt writes: ""Pinhols, matte surfaces, and rawling sometimes result due to its high viscosity and surface tension, [...]". So that also explains why it's matte. Probably also completely oversaturated with something, considering the graphite-like blackness.</db:para>

880 instead of chrome green. What could have been the cause? The keys
881 is likely in what John Britt writes about Chrome: "In a glaze that
882 contains tin oxide, the chronium oxide encourages some pink
883 coloration; in one that contains zinc oxide, adding chronium oxide
884 will produce browns. In high barium or sodium glazes, less than 1
885 percent chronium oxide will produce intense <db:phrase
886 xlink:href="http://en.wikipedia.org/wiki/Chartreuse_%28color%29">chartreuse</db:phrase>
887 yellow/green colors. Chrome oxide is unaffected by oxidation and
888 reduction."(The Complete Guide to High-Fire Glazes, p. 22). Hence,
889 relevant questions are: was barium carbonate forgotten? Was Zinc
890 confused with Tin? Is Nepheline Syenite a Custer Feldspar? What
891 provides sodium?</db:para>

1380 <db:para><db:date>2008-08-16</db:date> It's very speckled. I suspect it's because of the short soak time: only ten minutes, while the recipe specifies one hour. Could even be shorter/lower, considering the age of the oven. Simply, the cobalt doesn't manage to disperse. Think the same reasoning can be applied to <db:xref xlink:href="#W412"/> or <db:xref xlink:href="#W412"/>, which have black particles. It's manganese perhaps, considering how easily iron usually melts.</db:para>
