<p>[QUOTE=&quot;-jeffB, post: 7996760, member: 27832&quot;]Yep. I&#039;ve got a few square inches of platinum foil that I expect to use someday for electrodes, but making it into a little tray is also tempting. (It&#039;s that &quot;dead soft&quot; stuff I mentioned above, though, so it probably wouldn&#039;t hold up very well.)</p><p><br /></p><p>But apparently if you melt lye or another strong alkali in it, it&#039;ll get chewed up very quickly. I was kind of disappointed to learn that -- I always wanted to try making some potassium, and it&#039;s discouraging to think that I could trash a <i>very</i> expensive electrode in the process. (I tried it at a very small scale with a steel wire and plate, and got <a href="https://en.wikipedia.org/wiki/Ferrate(VI)" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://en.wikipedia.org/wiki/Ferrate(VI)" rel="nofollow">ferrate</a>, which I <i>also</i> never knew existed. I eventually got somewhere with a graphite electrode, reproducing Davy&#039;s original discovery. Got some tiny metallic-looking lumps that tarnished instantly, and flashed purple when I tossed them into water.)</p><p><br /></p><p>Oh, um, sorry for the threadjack... <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie10" alt=":oops:" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
