“Slice-Acado” by Ralph Rinke
Country: North Vancouver, British Columbia, Canada
Parts used: Skins: cleaned off all the flesh and chopped finely
Amount: 30 grams
Extracted by: Soaking in 100 mL distilled water with 10 mL of ammonia added, over
a period of one to two weeks. The ammonia will bring out the reds: shake/stir to
aerate the emulsion every day to intensify the colour
Thinner: Distilled water for smoother, easier coating
Application: Brushing with synthetic brush
Layers: 6
Substrate: Watercolour paper, Stonehenge, white 250 gsm cotton rag
Created with: Positive on Fixxon transparency material printed with Epson P600
Exposure: Approx. 130 hours/17 days over 4 weeks; about 7.5 hours per day, June 06-July 03, summer, 2023
Contrast: ✿✿ (Medium)
Challenges: Subsequent prints had a lower contrast and were solarized in the shadow areas. This was the case with emulsions from both the avocado skins and the avocado pits. This could be due to a variation in the avocados used.
Additional information or observations: Prints produced from the avocado skins are a dark reddish brown colour and had a coarser texture (the emulsion was not filtered), whereas prints using the emulsion from the avocado pits are a lighter pinkish brown colour and had a very fine smooth texture. When collecting your avocado skins and pits for printing, save them in the freezer.
