After that, I colored all the minerals and did my own bracket poster.

(I have it printed. I'll post a photo eventually).

Last year, for Mineral Cup 2025, I ink-sketched all the minerals in a handmade sketchbook as an exercise to learn more about minerals. This was the result:

#mincup #mincup25 #mincup26 #minerals #sketchbook #sciart

a collage of 16 photos os my minerals sketchbook, each photo a double page spread with two different minerals inked, the ones who participated in the 2025 mineral cup.

Exploring in my studio yesterday.

Four canvas boards. Each covered in a home made ink (Charcoal, Burnt Umber, Caput Mortuum, Red Ochre). Each with first Turmeric, then Indigo alcohol-based inks dropped into the centre.

I love how each base layer reacts differently
