@sciencebase Yes, some low confidence though.
@sciencebase Are you going to tell answers?
@sciencebase I suspected capsaicin for a phal attack.
@sciencebase All the PPE needed when etching aluminium samples with HF? What is going into it?

"I've always found Rwanda to be a very inspiring country," says Suella Braverman
After being shown these US State Department findings of major human rights abuses by the Rwandan government, Braverman refuses to comment but insists again that it is a "safe and secure country".
@drhafezster More...see if you can snap the Soup Dragon!

Am I the only person who thought this was a caterpillar at 1st glance?
@sciencebase I bet you know but Powerpoint does that.
@RedEx1 But it was full of little bits of slag which weren't a big deal until we made small items like clock springs. They floated out if the steel could be melted. It was achieved in Sheffield and made it the centre for steel across Europe. Crucible steelmaking (in ceramic pots).
Refining out the carbon to make steel was a carry on called 'puddling', but it was tougher so we could make thin edged tools for cutting without them forever breaking. As the C comes out the mpt goes right up though so no one ever melted steel. It was all solid state.
@RedEx1 We were dead lucky that all the carbon in the iron, from making it, massively dropped its melting temp and made it easy to cast into pots. But it was brittle stuff and no good for much else, tho you know it could be used like stone to make bridges.
@RedEx1 Thanks. From what I can tell the pot crucibles for melting metal didn't spin off into better cookware but then cast iron stuff probably did the job by then.
@RedEx1 I wonder, was they any big advance in making pots, alongside steel, when we managed to make to build much higher temp furnaces? Say around 1750 in the UK.
@sciencebase That's what I was vaguely remembering, thanks.
@sciencebase Isn't there a Butterfly that goes with it? Can't find it.

England, Germany, Denmark, Belgium, the Netherlands, Switzerland and Wales should pull out of the World Cup and play a friendly tournament instead. It would get more viewers and destroy FIFA. Norway are also invited, as long as each team gets to borrow Erling Haaland for a game. (Ideally the game against Norway.)

Huge blow as landmark Grimsby seafood factory closing and investing instead in their plants within the EU.

I am so incredibly tired of writing posts about what actual poverty looks like only to get replies saying words to the effect of put a jumper on, eat porridge, how dare you have any source of entertainment or pass-times, a dangerously bad home is still a roof over your head, if you were actually poor you wouldn't have a car, etc.
It's ignorance masquerading as informed perspective, it insults the intelligence of >14 million UK residents and it's blamey as fuck.
I've no patience with it.

Just a reminder that there isn't any need to go further into Hancock's nonsense than to say that a comet or whatever big enough to erase a global civilization did not strike the earth in 13000BC. It simply did not happen. There is zero geological evidence for it. Everything he then says is based on a lie. The End. #AncientApocalypse #archaeology #pseudoarchaeology https://www.science.org/doi/10.1126/science.362.6416.738
