Lead argument

Paint left the studio when somebody made it portable

A screw-capped metal tube held colour that could be closed again and carried. Around the same span the colourmen were selling chrome, cadmium and cobalt — a palette that had not existed a generation earlier. Where a painting could be made, and what it could be made of, changed together.

Standing distance is part of the work: a canvas sized to the wall asks the body to move back until the picture resolves.

Raking light does the reading for you: the cracks follow the weave of the support and the drying of the layers above it.

The eight arguments

Every entry is one cause and its consequence

02

Outdoors

What portability did to the horizon.

06

Scale

When size became the subject.

08

The Canon

How the list gets made, and by whom.

Chrome yellow is lead chromate; cadmium reds and yellows are sulphides; emerald green is an arsenical copper compound the trade sold regardless.

The material argument

A palette is a supply chain before it is a style

Industrial chemistry handed painting a set of colours it had never had, and the brightest of them were cheap enough to use in quantity. Synthetic ultramarine replaced a blue that had meant grinding a semi-precious stone.

None of this dictates a picture. It changes what is cheap, what is bright, what is stable and what a painter can carry — and those constraints show up in the work long before anybody writes a manifesto about them.

Commercial house paint and unstretched canvas on the floor made a size that easel practice could not reach.

Sent to the shop

Ordering an object from an industrial fabricator by drawing and specification, and what that does to the idea of a hand.

Nothing here is a parade of masterpieces. It is an account of causes: what was available, what it cost to do, who was allowed to show, and what the work looks like as a result.
