Some magnesium reacting is probably not an issue for you unless your supply of oxygen is limited, but I once bought 10kg of magnesium and am yet to run out of it.</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> this reminds me of reading someone&#39;s dumb thermite recipe on the internet like 30 years ago. (Maybe in The Anarchist&#39;s Cookbook?)</p>

I&#39;m considering the &quot;fool around with gas mixtures&quot; approach.</p>

Something that can mix 98% Ar and 2% CO2?</p>

<p><span class="h-card" translate="no"><a href="https://is-a.cat/@pl0myk" class="u-url mention">@<span>pl0myk</span></a></span> casting magnesium would require somehow ensuring it remains not in contact with oxygen the entire time, which is a pain</p><p>i suppose i could make like a fusible riser that melts and gives the already molten volume of magnesium access to the lumen of the mold, but ehhh</p>
