sample 36 limestone we cut a slice off to reduce the weight. slicing it thinner was too dangerous, hans was afraid to saw his fingers off. the glue is specular and is clearly visible at specular positions. the sample has a white area in the upper right corner that looks a bit like chewing gum, but it is really part of the texture. 4:49 pm starting set aperture at 11 refocussed. i continue with this one tomorrow 10:23 am parameters z=360 p=18 l=177 during the measurements i zoomed in to 1 tick before 90. i will take a millimeter picture afterwards. this is because this sample is smaller. the calibration was done at normal zoom. 11:59 finished (i did lots of things in between) millimeter paper saved as mil36.bmp
