1972 – Jan and Dad	Putting the cones into sacks.	The green cones are spread out over a floor of an oven.
Coke stoves provided a constant temperature of 49 °C.	Due to the high temperature the cones open.	By means of a shaking sieve the cones are shaken and the seeds fall out. Here you see my father and mother at work. This sieve is a modern version. Formerly everything was sieved by hand.
Peek under the sieve.	Pine seed (uncleansed).	Pine seed with coat.
