Plan B was to use the samples I prepared in York and Liane prepared in Leeds - these are simply balls of calcite embedded in araldite. We tried microtoming these and the samples just crumbled. It looks like the balls are too fragile to slice into 10 micron thicknesses.
Plan C is to have a final go with basic granules and the cryomicrotome tomorrow but the feeling is that it's a long shot. Plan D is to simply crush the granules and look for amorphous calcium carbonate in the powder - we'll try that tomorrow or possibly Friday depending on how things go tomorrow.
For our next beamtime in February we'll prepare some "classic" thin sections which should definitely work.

In the meantime we are running some of Steffi and Liane's snow algae samples that have simply been smeared onto slides.
Liane is now off to bed (11 pm). Steffi and I will stay up until 2 am to put on another sample then we'll reconvene at 9 am tomorrow.
Oh the joys of beamtime
