Fun with phytoliths, part 2
|Deflocculating the clay particles. Don't forget to label the beakers.|
|Rinsing beakers into crucibles|
When the time is up, carefully pour the water + clays down the sink - you sohuld be able to pour most of it away before the silt and sand sized particles start moving from the bottom. As soon as this happens, stop pouring or you'll lose some sample. Then, add the water back up to the mark and repeat, until the water is clear. As you can see in the photo above, some of the samples are very dark. This tends to mean a lot more clay particles, and can take up to 8 hours to remove. When the water is clear, it's time to transfer the samples into crucibles for Stage 3 - removal of organic materials!
