Cotton + blankets

Cotton mordanted with Gallnut Tannin plus Alum Acetate and Calcium Carbonate (T+AA+CC).

Four pieces.


In this experiment I used iron mordant instead of iron dip. Here is the difference:

Iron mordant

Measure iron at 2% WOF. Dissolve in hot water.

Add to mordanting pot. Fill the pot with enough water to fully cover the fibre when added. 

Add wet, mordanted fibre.

Heat to 55ºC (130ºF) hold for 30 minutes. 

Rinse well.

Iron dip

Measure iron at 2% WOF. Dissolve in hot water.

Add wet, mordanted fibre.

Leave it 30 seconds. No rinse.

Experiment 1

Target: T+AA+CC+ orange osage dye

Blanket: NO

Botanicals: dry and fresh petals

No plastic barrier


 

Experiment 3

Target: T+AA+CC+ I mordant

Blanket: chestnut tannin

Botanicals: hydrated dry leaves

When mordanting cotton with Iron, became gray because it was the mordanting process for cotton contain tannin. In silk, can be mordanted with iron and still keep the natural color (since there is no tannin involved in mordanting silk).

The blanket introduces yet more tannin, so the grey is stronger.


Experiment 2

Target: T+AA+CC+ I mordant

Blanket: orange osage dye

Botanicals: hydrated dry leaves

The blanket got more interesting effects here. Experiment to try: dye in target, iron in blanket.

Experiment 4

Target: T+AA+CC

Blanket: orange osage dye

Botanicals: hydrated dry leaves
