From what I've read, it's at around 1200* F.Wow impressive. I'm actually impressed by at least 2 things:
1)I would have thought that the aluminium wouldn't go that deep without solidifying. It must have been extremely hot, significantly hotter than the melting point?
2)The ant nest is surprisingly small to me... with a single entrance?!
The melting point is: 1,221°F (660.3°C) and the boiling point is: 4,566°F (2,519°C), so there seems to be a lot of room for pouring it well above the melting point. How hot an amateur can get it is probably most dependent on what kind of crucible they have available.From what I've read, it's at around 1200* F.
I would imagine it's trial and error. If it cools too fast one time, keep it in the furnace longer before the next pour. That sort of thing.Well in the videos I've heard them say "pouring 1200* F into an ant hill" but I suppose it is likely that they just looked up the melting point and put that number.
It seems like if it was near the actual melting point, most of it would be starting to solidify by the time they were pouring, and whatever came out would be 'blobby.'
With all this in mind, casting ant nests is much less demanding than it looks, despite the complexity of the nest.Earth is a fairly good insulator, so it doesn't take the heat out of the aluminum too fast. The traditional way to make metal castings was using sand moulds. The main difference is that earth probably has a higher water content that industrial molding sand.
You don't need exotic crucible materials to cast aluminum. Iron doesn't melt until about 2700F (1500C). You should be able to get aluminum up to about 1600F with a simple gas furnace. Casting aluminum barely get the iron glowing red hot.
You may get a different reaction from people who live in fire-ant country in North America.... These ants are solenopsis invicta, a non-native invasive species that is destructive to native flora and fauna and a very unpleasant neighbor.Someone call PETA.
I think that is "art" as a synonym for "craft" - or the section in Patent applications that used to be called "Prior Art", i.e. what other people had already done.art 1 (ärt)
1. Human effort to imitate, supplement, alter, or counteract the work of nature.
This guy is selling the casts. He is killing ants to make money. For all we know he could be searching for large ant hills with a bucketful of aluminium in his hand, thinking about his next sale. It is morally questionable so yeah, I was being serious.I think this was originally done to study the form of the nest. In any case, if killing them just to kill them is acceptable, then killing them with the added benefit of creating art is acceptable.
And then, there's also the fact that they are just ants.
Brilliant! We should show this video to all the exterminators in the south. Not only would we be rid of a hideous invasive species, we'd have tens of thousands of pieces of art for sale. I think they'd make great x-mas presents.This guy is selling the casts. He is killing ants to make money.

Strawman. You lose....
Are you serious about "Just ants"? If all ants were to somehow vanish...
