How to get natural colours from dried plants using hot infusions
I choose the powdered plant material (herbs, petals or seeds) and add into my oil, then mix well in a sealed bag. Place the sealed bag in a slow cooker with water and cook for 2-3 hrs on low heat. Turn off the heat and leave the sealed bag in the water until it is completely cool to the touch. Filter out the coloured oil for soap making.
I love to use sweet paprika infused oil to colour my soap, it gives my soap with beautiful bright orange colour.
