The living record of a work: technique, support, pigments, condition

A work is made of things, and those things age. The material record says what they are and how they were on a given day, so the next owner, framer or conservator starts from the truth.

ByErick González

Naranja, Camila Baeza

When we talk about a painting we talk about what it shows. When a conservator talks about it, they talk about what it is made of. Both conversations matter, and the second one is the one most collectors only start when something goes wrong. A material record starts it on the first day.

What the record holds

Technique. Oil, acrylic, gouache, ink, a print process. Precise words, not “mixed media”.

Support. What the work is painted or printed on: linen or cotton canvas, wood panel, paper and its weight. The support decides how a work reacts to the air of a room.

Ground and surface. Whether the canvas was primed, whether there is a varnish, whether the surface is thick or thin.

Pigments and materials, as the artist names them. A record that keeps the colours the artist used helps any future retouch match the hand, not guess at it.

Condition, with a date. A few lines and a few photographs: the front in even light, the back, the signature, the corners and edges, anything already there such as a small crack in a thick passage.

Why we call it living

A condition is a sentence with a date in it. A work that hangs in a sunny room for ten years, travels twice and is reframed once is not the same object as on the day it left the studio, and that is fine. What matters is that each moment is written down: who looked at it, when, and what they saw. Read in order, those lines become the work’s health record.

Three habits that cost nothing

Photograph the back of every work the day it arrives. Labels, stamps and the stretcher tell their own story.

Ask the framer to note what they used: glass, mount, backing. It belongs to the record.

When a work changes hands, look at it with the record in hand, together. Disagreements end there.

Our certificates can carry the work’s material record beside its wall label (technique, support, pigments, condition), on the public page, the document and the pass. See how a certificate works; if you are an artist, the certificate wizard asks for it one question at a time.

If you would like company

This is what we do every day from Mexico City: help people find, buy and live with original contemporary art, with its papers in order. Book a free 30-minute call, or look at how our certificates work.

  1. Provenance in five questions

    Provenance is the life story of a work: where it has been and in whose hands. Five questions, asked calmly, tell you most of what you need to know.

  2. When a work is sold again: the resale and the artist’s share

    A work you love may one day go to someone else. How a resale works, what the artist’s resale right is, and why we like a world where the artist is not forgotten.
