Asked by Andrew

when the beaker has rated capacity of 10 ml, does it mean that it has to be filled to the brim?

No. Chemical beakers usually have an etched line in the glass where the liquid level is supposed to be when "full"

I didn't know that. I guess I always used "backward" beakers. Isn't technology great?

I answered based upon what I remember from college and high school chemistry. That was over 50 years ago. Apparently I was wrong.

There are such things as calibrated beakers. Some are shown at

No, you probably are not wrong and I didn't doubt you. Your schools may have had the money to buy those calibrated beakers and mine didn't. Those calibrated beakers really are quite nice.
