• Heat onion skins in white wine then reduced to 1/4
• Add Alum mordant (pH3) = Yellow
• The Yellow dye was mixed with chalk then left to naturally dry = Orange pigment. 

• Quarter of the onion can be crushed then sieved through a fine mesh which can be used to stick the onion skin pigment. 

Method:

• Heat the flowers in water and reduced by 1/4.
• Add Alum mordant (pH3) = Yellow 
• Add Tin mordant then a small amount of chalk = Orange Paint

Method:

• Break the stem or root of the plant which will bleed a bright orange sap 
• The sap can be applied onto the silver / tin leaf from the stem, representing an imitation gold
• The sap can be irritant to the skin

Method:

• Dried coreopsis flower are heated in water and reduced to 1/4
• Add Bicarbonate of Soda mordant (pH9) = Orange
• Add Alum mordant (pH3) = Orange

Method:

• Heat flowers in water and reduce down to a 1/4 (ph7)
• Add Potash mordant (ph12) = Yellow /Orange
• If the dye is painted onto aluminium-foil it can produce an imitation gold colour.

Method:

• Heat the flowers in water and reduce down to a 1/4
• Add Alum mordant (pH4) = Yellow
• Add Potash mordant (pH12) = Dull Orange / Rust

• Heat the flowers in water and reduce down 1/4 (pH5)
• Add Alum mordant (pH2) = Yellows
• Add Potash mordant (pH12) = Rusty Browns (Flowers)
• Add Iron Sulphate mordant (pH2) = Browns

Method:

• Heat and crush the unripe berries in water and reduce down 1/4 
• Add Alum mordant (pH3) = Yellow-Orange

• Heated the flowers in water and reduce by 1/4 (pH5)
• Add Alum mordant (pH3) = Yellow
• Added Biocarbinate if Soda (pH9)= Orange Yellow
