[meteorite-list] Tissint - Density Measurements - UCF

[Greg Hupé]

Hello Martian Fans,

Yesterday I drove up to the University of Central Florida (UCF), Orlando, 
with the 91.3g Tissint individual to have some density measurements 
performed by Dr. Dan Britt.

Dr. Britt using tiny glass beads as the medium to determine the bulk density 
measurement for this sample from the Tissint Martian meteorite. The stone is 
submersed in the cup containing glass beads sitting on the vibrator to allow 
the beads to fill all the surface voids and contours. The vibrator in run 
for five seconds for each measurement.

helium as the medium for density measurement.

the pycnometer for measurements.

It takes approximately 1 - 1.5 hours to do both the glass bead and helium 
methods to measure a sample. There are several repetitive steps needed to 
get enough measurements to get an overall average density for the meteorite.

Best Regards,
Greg
