hope we have a monthly crystal growing contest soon
first picture is the best one for me... it looks really clear
good job my friend
thescottandrew said:Yes, the first pic were crystals that evaporated from heptane at room temp for 4 days. The others were from evaporating at room temp for 12 hrs, then 24 hrs at 3 C, and 24 hrs at -16 C. I will definitely use the first procedure from now on.
in summer its faster evap but in winter much longer i already noticed... thanks for info about temperature, i guess i need to use my thermometer next time and experiment evaporating in different temperatures
