This Natural Dye material contains all the tops and will produce yellow with an Alum mordant, if modified with iron a lime green can be produced.

Use at a rate of 100% per dry weight of fibres.

An Alum mordant is required for protein fibres.

A tannin and Alum mordant are required for all cellulose fibres.

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 marigolds.

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 gold yellow
Alum + Citric Acid = gold
Alum + Ammonia = warm brown gold
Alum + Copper = warm gold
Alum + Iron = golden green

Not food safe, so please do not make a drink with this dye.
