£3.00 inc. VAT

Schinopsis lorentzii

The dye comes from the heartwood of the Quebracho Tree which is found in South America. This dye contains a lot of tannin, so it can be used as a tannin or as a dye.

When used as a dye use at 20 – 30% per dry weight of fibre.

When used as a tannin use at 15% per dry weight of fibre then mordant with Alum if used on Protein fibres. If to be used on cotton used at 15% then Use either Aluminium Acetate or Aluminium Lactate.

For cellulose fibres use either
Aluminium Acetate at 5% in a heated mordant bath.
or
Aluminium Lactate at 5% in either a cold or heated mordant bath.

The picture shows wool which has been mordanted with alum, then dyed with quebracho.

The left-hand skein shows how all the skeins originally came out of the dye pot. The other four were each dipped into a different modifier bath for approximately 10 minutes. From left-to-right these modifier baths were Citric Acid, Ammonia, Copper and Iron.

The dyed samples are as follows
Alum – no modifier = deep brown pink
Alum + Citric Acid = pink orange
Alum + Ammonia = pink
Alum + Copper = warm brown
Alum + Iron = dull purple
