Mineral/element sample in capsule

Thu, Jun 20, 2024 6:23 PM

Hi folks,
We’re going through some old specimens and donated items and came across this (see attached image). Does anyone know what collection it might be a part of? It has small pieces of a metallic sample inside the capsule and has a number 11 on a Riker Specimen Mount container from Wards (with no additional information on back—specimen information is blank).

If anyone knows anything about what collection this might be a part of, I appreciate the info!

Cheers,
Amy

I don't know what collection this is from, but have had several similar
specimens in the past, in similar gelatine capsules. The contents are
probably alluvial PGM minerals, native platinum or osmium, etc. The source
locality would be more difficult to determine, but specimens like this with
somewhat lamellar grains probably used to be most prolific (on the mineral
specimen market) from the Ural Mountains, Russia, although other regions
are possible too.

Element #11 - sodium? Would have to be in a hermetically sealed capsule as
sodium reacts with water.

If you are confident this is from Ward's, it is likely one sample among a set of 20, 50 or 100 minerals that they were selling as sets. For this particular sample, I would think simple and inexpensive (given it is number 11 in a set). I would bet either native silver or bismuth. Both are common among mineral sets. If you want to find out quickly what the sample is, bring it to an SEM or microprobe and use EDS to determine the elements present. The samples are metallic so you won't even need to be carbon coat them. Just stick a chip down on a double sided piece of tape and do EDS. Short and simple. 

Hope this helps.

Yes Pt from a placer.
Without removing from the gelatin capsule weigh the sample..
Subtract an empty capsule weight based on hints from the pharmacy
department.
Binocular microscope measure dimensions to estimate volume.
Volume and mass gets density.
It looks like Pt I have seen, Russian River, Calif. placer pannings.

Non destructive analysis might include XRF.
