Making Madder Lake - Part 4

The sediment (which is actually the madder lake pigment that will result from this process) has now settled to the bottom of the bucket after being left undisturbed for 36 hours. You can see in this picture that the water is more transparent at the top of the bucket:

The next step is to use a siphon to siphon half of the water from the bucket into a separate bucket. The siphon is used to avoid disturbing and removing the sediment / pigment from the bottom of the bucket:

With half of the water gone from the bucket, you can see the madder lake pigment at the bottom of the bucket:

Because the water removed isn't entirely transparent (see the color of the water in the small glass jar in the photos above), the bucket will again be filled with cold water:

Because adding water has disturbed the sediment/pigment, the mixture will again be left undisturbed, this time for 24 hours, and the siphoning/washing process will be repeated. This process will be repeated until the siphoned water is clear. I will post an update at that time.
