Thanks for the data, but it seems like you guys are getting different numbers. Maybe you have different versions of the Evernew 1.3 pot? Per Evernew's website, the 1.3 L pot is 4.6 oz (including lid) and the 0.9 L pot is 4.2 oz (including lid). But actual weights are more helpful than manufacturer suggestions.
What would be really cool is if someone collected all this data and posted it somewhere online. Personally, I keep an excel file of all the stuff I've weighed (My list includes 247 items at present).
Hopefully someone else will chime in here...
