Here's a description from Ira Katz's "Techniques of Non-Silver
Photography"-1987
"Description: This process is merely the grinding up of petals of
flowers in a mortar and then adding a little alcohol to the ground-up
flowers. Then this substance is strained through a cloth and spread
onto a piece of paper with a brush. It is then exposed to light for
about 2 weeks- one month with the negative over it.
Materials and Supplies:
1. Mortar and pestle
2. Piece of cloth.
3. Petals of a rose, poppy, violet or carnation.
4. Alcohol.
5. Brush, paper, negative.
Process:
1. Peel off the petals of a flower and place them in the mortar.
2. Grind the petals until they are thoroughly crushed.
3. Add alcohol to the pulp and mix well.
4. Strain this pulp through a cloth and brush the liquid result onto a
piece of paper.
5. Expose to light (sunlight or arc-light) through the negative you
desire.
