359 <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>

477 <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>
479 <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>

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

1218 - What is a /secondary/ flux?
1219 - What does UMF mean?
1220 - Where shall one throw glaze slurries? Paining oxides?
1221 - What's the mesh size on the sieve at liv i leire?
1222 - What is the black stuff on T246?
1223 - Why did 182 come out as it did?
1224 - Why did 234/243 come out as it did?
1225 - How should one lowering the melting point of a glaze? A cone or two. Say NewGrassGreen.
1226 - How should one approach food safety? Should one only use liner glazes? When is a glaze food safe?
1231 - 0.2 chrome + 0.2 - 0.5 Cobber => gives strong yellow/green. Pending new weight.
1232 - 0.25 - 0.50 chrome + 0.2 - 0.5-1.5 Cobber => gives strong green. Pending new weight.
1233 - Investigate Gloss Black Breaking Brown
1234 - Investigate Barnard Slip, why does it cause wrinkles?
1243 Do not have melt tests for:
1245 * Wollastonite, P3348
1246 * Potash Feldspar, P3296
