As promised, here’s some video of my recent fun with Wood’s Metal. Thanks to Phil for recording this.
Some basic stats:
I’m still testing different materials to find some combination that will prevent the metal from sticking to the container. Acrylic by itself doesn’t do so badly (far better than glass at least) but there’s still significant stickage. What I would really like is to find something that will let the metal flow and move somewhat like mercury.
A friend recently suggested that I just use mercury but it’s far too toxic for my tastes. I’d be one spill away from turning my lab into a Superfund site.
Other things that I’ve tried:
|Worked well for a while but then turned white and powdery. I suspect that it slowly cooked.|
|Mineral Oil||Worked marginally well but didn’t prevent enough sticking|
|Water||Less effective than the mineral oil|
|Silicone Lube||Epic Fail. Actually, this had the curious property of making the metal stick evenly to everything it touched, lining my container with a thin sheet of metal. Might be useful if it wasn’t the exact opposite effect I was going for.|
Based on accounts I’ve read online, I suspect I may never find a ‘lube’ that makes acrylic perform the way I want. A common experience (and similar to what I’ve been seeing) is to find something that works for a while but then fails.
I may have to resort to simply lining the bottom of my container with teflon.
