Titanium Oxalate
Titanium oxalate is an alternative mordant for use with natural dyes on both protein and cellulose fibres. Titanium will produce a distinct palette (for example it gives a bright orange when combined with dyes containing tannin). Sample test to determine colour.
Use at 8-10% WOF, dissolved in hot water. Add to the dye bath, add fibres and cook for 45-60 minutes at 170-190° F (75-90° C), stirring frequently.
