Elemental Dice 1 – 3

There has been some Kickstarter projects under the name Elemental Dice. Backers get dice made of “pure” elements, well as pure as possible. When it comes to very valuable elements (like gold) the dice are just plated with pure gold.

The first 3 Elemental Dice projects contained 15 different elements:

I decided to weight them and present some stats:

The side of the dice are 16mm. But there are cavities and roundings so their actual volume is slightly smaller.

The plated dice all weight 34-35g, and they probably have the same interior. Their weight is rather uninteresting.

When it comes to the “as pure as possible dice” most of them are more or less within the error margin of my 1g resolution scale. Iron (Fe) seems to be an alloy with something lighter and Zink (Zi) even more so.

As expected, Nickel (Ni) and Iron (Fe) seems to be magnetic.

Silver

2021-10-14: I wrote separate post about the two silver dice and questioned some of below conclusions.


Silver is a noble metal, but everyone who has owned silverware knows that it gets blackish after a while. After a while I had the feeling that my silver dice were the ones that had deteriorated the most since I received them. I happen to own silver dice: one solid and one that is just plated.

Today someone who should know told me: pure silver does not oxidize like that in air. I had a closer look at them, and decided to take a photo:

This has obviously been a gradual process. The one to the left is the oldest die and is plated. The left die actually is that much darker on its 6th face. Since they are next to each other you can see it is just not a light reflection phenomena. The dark corner on the right dice IS the left die being reflected though.

As you may be aware of, the 6th face is opposite to the AG-face. I have kept my Elemental Dice in the aluminium stands, with the 6th face downwards, in contact with the aluminium. As you can see on the 3rd face, the stain/oxidization is triangular, being larger on the side that has been more down in the aluminium stand. And on the 2nd face, you can see kind of a line where the dice has touched the aluminium.

I feel quite confident that there is a reaction between Al and Ag, and that the silver dice (or silver in general) should not be in contact with Aluminium at all.
Not so sure about this any more, see separate post liked above.

Also, the little “holes” in the left (non-solid) die have turned yellowish. I don’t think is an optical phenomena because it has not happend (yet) to the solid silver dice, and there is nothing yellowish about Pt, Pa, Rh.

I am considering to paint my Aluminium stands with clear nail polish. Any other ideas?

Cleaning it!

There is a very simple way of removing the tarnish: link. It just requires sodium bicarbonate and some aluminium foil. The result is amazing, and it is fun do to chemistry in your own kitchen! Basically the Aluminium metal is sacrificed (oxidized) to restore the Silver atoms from Silver Oxide (and perhaps Silver Sulphide) to metal form.

Wishlist

There is a new set of Elemental Dice 4 with 10 new dice coming. The most missed ones after that would be:

  • Gallium – with a melting point of 29C it poses some practical problems, but including a mold for it would be cool
  • Uranium (depleted) – export restrictions and perhaps someone clever can turn U238 into Pu239
