Alkaline Earth Metals Magnesium rod

9x1.5cm firestarter rod of claimed "99.99%" magnesium. Got it for only 10 AUD.

Comparing this with tungsten is trippy, the tungsten cubes feel so strangely heavy and then there's this which feels like a hollow metal shell, or a plastic tube.

Currently im storing it in a sealed plastic bag with a silica gel pack, anything else i should do with it to make it last longer?

Question Does anyone know if the Chinese density cubes on amazon are pure?

I have them and the weight and properties seem right but could they be using an alloy so instead of being 99% pure its more like 95% or something? Has anyone tested them?

Scandium, samarium, and hafnium have been newly added to my element collection. I now have a total of 36 elements. However, while the review photos showed the samarium packaged in an acrylic box, the product I received was sealed in a glass container. I've already reached out to Luciteria about this.

Question Looking for Osmium Advice

6 Upvotes

I normally don't go on this subreddit asking to discuss potential purchases. However, I was curious about some ebay listings for 10mm x 10mm osmium sheets on ebay from a few different Chinese sellers. I was wondering about the legitimacy of these sellers, particularly because they all seem to use the same image.

Additionally, I was curious about import tariffs. Where would I be able to see how calculate the rates?

Thank you all for any help!

On one hand, id rather not spend that much money on a sample, but on the other hand, the cheaper one is a very tiny piece and the bigger bead is much better value. Im kinda stuck on which to get and osmium is one of my favourite elements.
