Note: Dry taken 23 Feb after air-drying in the lab for 3 days.  Will repeat after baking in the toaster oven for an hour to see if any more moisture boiled off...

tare = c(5.58,2.15,2.50)

wet = c(100.74,99.59,89.51)-tare

dry = c(85.03,88.59,80.32)-tare

vol = 3*pi*(5.31/2)^2

moist = 100*(wet-dry)/vol

rho = dry/vol

ec5 = c(23.98,16.38,13.17)

matplot(moist,ec5,xlim=c(0,60),ylim=c(0,60)); abline(0,1,lty=2)
