# = weighed wet a day later (but kept cold to reduce water loss)unmigrated-wiki-markup
\* = weight after a bit of time in the oven \ :( \ [forgot to write down first reading\], water content will be a bit low, but dry density will be okay
Here is a quick comparison of the weights of various objects with the borrowed scale and ours. The borrowed scale read within 1g, so I wouldn't change any of the above readings.
