The next dye, in alphabetical order, that we experimented with was from the barberry family, namily berberis chitria, or daru haridra in hindi.
First the cold baths.
I will start out with the picture of the 1 month wet- and dry-aged, 25% alum yarn in a cold bath. The wet is on the left and the dry is on the right.
I really cannot see any difference in these and will stop posting the results of this sub-experiment unless something unusual catches my attention in the future. Again the dry method seems to conserve the fiber quality a bit better than the wet method.
Berberis on alum, in a cold bath: there was very little different alum concentrations, so I will omit the details this time.
The fiber quality was constant throughout and again the best of all mordants used.
Berberis on copper, in a cold bath: mordant concentrations do not make much difference here as well, and the colors do not really appeal to me
Berberis on iron, in a cold bath: 1. 1% Fe; 2. 1% Fe + 2% CoT + 1% Glauber’ Salt; 3. 2% Fe; 4. 2% Fe + 4% CoT + 2% Glauber’ Salt; 5. 4% Fe; 6. 4% Fe + 6% CoT + 4% Glauber’ Salt
A nice selection of shades of olive green, and almost identical result to the hot bath.
Berberis on tin, in a cold bath: 1. 2% Sn; 2. 2% Sn + 2% CoT; 3. 2% Sn + 2% Oxalic Acid; 4. 4% Sn; 5. 4% Sn + 4% CoT; 6. 4% Sn + 4% Oxalic Acid; 7. 8% Sn; 8. 8% Sn + 8% CoT; 9. 8% Sn + 8% Oxalic Acid.
Again, the most exciting of the bunch, but the fiber problems persist.
Berberis on merino in a cold bath: 1. 4% Sn + 4% Oxalic Acid; 2. Cu 4% + 8% Citric Acid; 3. Al 15% + CoT 5%; 4. 2% Fe + 4% CoT + 2% Glauber’ Salt;
Berberis on angora/merino in a cold bath: 1. Cu 4% + 8% Citric Acid; 2.Al 15% + CoT 5% ; 3. 2% Fe + 4% CoT + 2% Glauber’ Salt; 4. 4% Sn + 4% Oxalic Acid.
The fiber quality is excellent and even tin is superb.
And here are the hot baths.
Berberis on alum, in a hot bath: 1. Al 5%; 2. Al 5% + CoT 5%; 3. Al 10%; 4. Al 10% + CoT 10%; 5. Al 25%; 6. Al 25% + CoT 25%; 7. Al 50%; 8. Al 50% + CoT 15%; 9. Al 15% + CoT 5%.
Berberis on copper, in a hot bath: 1. Cu 1%; 2. Cu 1% + 2% Citric Acid; 3. Cu 2%; 4. Cu 2% + 4% Citric Acid; 5. Cu 4%; 6. Cu 4% + 8% Citric Acid; 7. Cu 8%; 8. Cu 8% + 10% Citric Acid.
Berberis on iron, in a hot bath: 1. 1% Fe; 2. 1% Fe + 2% CoT + 1% Glauber’ Salt; 3. 2% Fe; 4. 2% Fe + 4% CoT + 2% Glauber’ Salt; 5. 4% Fe; 6. 4% Fe + 6% CoT + 4% Glauber’ Salt.
Berberis on tin, in a hot bath: 1. 2% Sn; 2. 2% Sn + 2% CoT; 3. 2% Sn + 2% Oxalic Acid; 4. 4% Sn; 5. 4% Sn + 4% CoT; 6. 4% Sn + 4% Oxalic Acid; 7. 8% Sn; 8. 8% Sn + 8% CoT; 9. 8% Sn + 8% Oxalic Acid.
