With all of the germanium-bearing alloys it's possible to polish off the germanium oxide layer - and then the stuff'll tarnish again. It needs heat to form the oxide layer; if I've understood,...

Appraise? Identify?

Kerry's bloody good, as is Sam Maclachlan.

As for the apps themselves in their current guise - LMGTFY.

Most, perhaps, but not all...

There's not much empirical data on how jewellery alloys behave in fabrication primarily because there's so many variables. If I'm machining a piece of known steel on...

Really? A 9 year old thread? Hardly bodes well.
FYI, the OP hasn't logged in since 2014.

That's 4 today. Or was it 5?

Apologies - I was removing another spammer and deleted that twerp's posts by accident too.

A short-lived frisson.

It's a pity that coronavirus hasn't changed the behaviour of spammers though. You all exhibit the same patterns; I'd spotted you from post #1 and was just waiting to check my assumptions.

Yeah. About that - don't. I've banned the Grimee account now.

Not well-known to me, but if it started pulling out hairs I'd get fairly tired of it fairly quickly.

Are you sure you've posted the correct link?

Interesting point about Rustoleum; I've not seen that so much with Humbrol enamel, which is more readily available in the UK. I have found that the eco-friendly printing inks are very, very slow to...

There's a fair few ways of achieving the same effect. The bracelet I repaired has one end of the loop between the lower galleries fixed, the other moving (except that the other end in this case...
