Archimedes Method and Open Porosity

I've sintered some ceramics which seems to have open porosity. I had a discussion with my supervisor and some things remain unclear.

If one wants to measure the density of such a sample by using Archimedes method, water will enter inside the open pores. This isn't what we desire as water entering the pores eliminates the volume of open pores from the measurement. This leads to too high density calculated.

I concluded that the density of the samples with open porosity can't be measured using Archimedes method as a displaced volume in the liquid isn't the same as the actual volume of the sample.

Is this correct or I got something wrong?
