Are cheap plastic graduated cylinders useful? Yes, you can calibrate them yourself.

Wednesday 16th July 2014

Graduated cylinders like this are inexpensive (e.g. Amazon.com). Of course, these cheap plastic ones are not accurate. But, there is one factor that makes them useful: They are light and can thus be used to measure specific gravity on a 200g scale. There is a way to make these accurate enough for a potter: insight-live.com/picture/2222">Calibrate them by checking with 100g and 50g of water, just mark the levels using a Sharpie.
