Challenges or observations: This tree is also known as Indian redwood and is related to Brazilwood, a species native to my country that gave it its name. However, years of uncontrolled exploitation have brought the tree to the brink of extinction. Planting and extraction are now subject to severe restrictions, making the wood almost impossible to obtain. For some works, I use Indian redwood, which produces the same characteristic red colour. As it is not native to my country, I can only obtain it in powder form.
Additional information: I chose isopropyl alcohol for the extraction because it works fast. The resulting emulsion is orange-red, but turns pink when diluted with water. I believe longer exposure would produce better definition. I had to use a UV bed for the entire exposure, as El Niño brought many rainy days and very little sunshine to my region.
