<p>Lithium Carbonate or Lithium Fluoride are fluxes which make glazes runny. As a color, lithium contributes only a clear glass.</p>
<p></p>
<p>If you leave out the lithium, you have to replace it with more of another flux material like the nepheline syenite or the Ferro Frit 3269 which I add to my version of the glaze to be certain it melts at Cone 6.</p>
<p></p>
<p>The fluorine in the 3269 or in the Lithium Fluoride can add white whisps to the flow of the glaze.</p>

<p><strong>Water Color Green</strong> has many of the same ingredients, lithium, copper, calcium carbonate, and strontium carbonate. But <strong>it's missing the Ball Clay, titanium</strong>, and Nepheline Syenite Both lithium and Strontium color-shift copper to a bluish tint by making the molten glaze more alkaline.</p>

<p>I made <strong>Barbara's Strontium Turquoise Matte</strong> on the LEFT fired on four different clays.</p>
<p>and I replaced the Strontium with Barium on the RIGHT.</p>
<p></p>
<p>It's a typical Barium Blue as the Strontium or Barium shift the green color to blue, but not even close to a Weathered Bronze Green. Her recipe uses 25% strontium carbonate rather than 20% and leaves out the Titanium Dioxide.…</p>

<p>Normally I'd use a gram of water for a gram of glaze but the <strong>Strontium Turquoise Matte</strong> has so little clay it tolerates less than half the water. Initially using more water the glaze wouldn't apply except on extremely porous bisques.</p>

<p>Barbara,</p>
<p>By <strong>eliminating Titanium Dioxide</strong> I think you have found the cause of "Weathered Bronze Green" interacting badly with some clays to create a mustard or ugly brown color. I'm going to mix up a batch of your recipe this Saturday and will post the results.</p>

<p><strong>Titanium dioxide does not work like zircopax</strong> to provide a white background.</p>
<p>I once tried covering a darker clay with wash of titanium oxide, imagining I was covering a dark canvas with a ceramic guesso - boy was that a mistake! I got the same bubbly brown covering seen in Otto Wenger's container above.</p>
<p></p>
<p>The nepheline syenite in Weathered Bronze Green will leech salts over time after being mixed with water which will cause the glaze to hard-pan leaving you to apply only some of the components of the glaze. Weathered Bronze Green also began llife as a Cone 10 glaze which means it's under-fluxed for Cone 6. But I think in eliminating the Titanium Dioxide you've found the real problem.</p> I found the same to be true,…tag:cone6pots.ning.com,2019-03-20:2103784:Comment:1523122019-03-20T22:21:42.284ZBarbara Hanselmanhttps://cone6pots.ning.com/profile/BarbaraHanselman
