One year in one room.
A continuous year of large one-shot sumi ink paintings on paper, made in a live-in studio in Bangkok. One-shot means the ink cannot be taken back: a sheet resolves, or it is destroyed. This is the year as it was recorded at the time, week by week, with the numbers it left behind.
The idea.
Three dates mark the start, and the record keeps all three rather than choosing the convenient one.
On his 41st birthday, in Hanoi, Peter sets out a year of continuous one-shot painting on paper.
T_001, 100 × 200 cm. The year's count starts here, and so does this site.
The move to Bangkok; a studio is leased for the year and two large tables are surfaced in wool felt.
“The Crucible Year emerged as a need FOR stability as opposed to emerging from it.”Peter Yuill · 2026.03.01
The year is the ninth period of a practice that began in 2011, most of it built in Hong Kong. It is the first, in Peter's own account, that set out to build rather than to tear down. Why he staked a year on it is told on the opening page.
The room.
There are no sessions. Peter lives and works in the same space, and painting happens in fragments through the day and night, paced not by a schedule but by how many wet sheets the drying rack can hold.

A felt table, open on every side.
Plan of the studio table, to scale: two 120 × 240 cm boards joined in an L, 80 cm high, upholstered in 5 mm wool felt and open on every side, so a sheet can be approached from any angle. A standard 97 × 180 cm sheet is drawn on it.
“I'm not working over it depositing ink onto it, I'm painting into it as if it's connected to me, a direct conduit or an extension of my being.”Peter Yuill · 2026.02.22
The output.
Paintings are photographed in batches, so each bar is one photo day. April has 113 paintings and 189 m² of painted paper, the most of any month. Nothing is dated in August: the studio paused.
Every photo day, and what happened.
Each photo day is a stack of its own sheets, one tile per painting, lit where the painting is shown on this site. The cyan line climbs with the total area of paper painted. Amber pins mark the turning points the weekly reports recorded.
The year, hung on the wall.
Every painting at its true size and proportion, hung month by month in the order it was photographed: the area of paper is the area you see. Paintings shown on this site carry their photograph; those kept in the Archive hang blank, face to the wall. The April switch to premium paper was also a switch to larger sheets. Hover a sheet for its size; select it to open it.
The record.
For the first 28 weeks, every Sunday, Peter wrote a report with fixed sections: a raw account of the week, hours and works, steps, energy, the habits he was avoiding, what came next. 28 reports, kept unedited. The share of paintings destroyed fell from 100% to 24% as the work found its footing. From Week 28 the record changed rather than stopped: Neon asks him questions through the week and keeps a daily roundup, and his answers are kept word for word. Hours were no longer logged; Peter puts those weeks at about 60 hours each.
About 2,030 hours in the studio.
Each week is one brush column, drawn from Peter's own brush lines to the length of the hours he worked that week, and titled as that Sunday's report titled it. Solid where the report logged the hours; dry brush from Week 28, where they are Peter's estimate of about 60. In violet, the share of all paintings made so far that had been destroyed, kept while the reports recorded it. Hover a week for its report.

“This week was the first time in the Crucible Year I can see the light at the end of the tunnel as far as creating work goes.”Peter Yuill · 2026.02.22
The turn.
At the end of May, in the week his mentor told him he was a better artist than he was showing, Peter looked back over the work and saw what the counting had done to it.
“I had the realisation that I've been rushing works to try to get higher numbers because I was more excited about collecting the data than I was about actually making paintings.”Peter Yuill · 2026.05.31
Months afterwards the Oracle, which knew nothing of this decision, found the same thing in the record: busier fortnights, rougher surfaces. A lead that agrees with him, not proof.
“It's just proved you can't mathematically map out what good work looks like.”Peter Yuill · 2026.05.31
Stronger, then steadier.
Read by one engine throughout, the studio-photographed paintings rise month by month into June, then settle. March 4.1, April 4.7, May 5.6, June 7.1, July 6.1, September 5.7, October 6.1: the average V23 rating of each month with eight or more paintings. June, the first month after the decision to slow down, is the year's highest, 7.1 across 30 paintings.
Every painting, every month.
Every painting's engine rating by date. Lines: the weakest tenth and the best tenth of each month with eight or more paintings. Both climb through spring: the weakest tenth from 2.5 in March to 5.7 in June, the best from 5.4 to 8.2. Within each system later paintings rate higher (rank correlation with date: V23 0.60, V23 lite 0.45). The early months rest on V23 lite, read once from phone photographs and about 0.8 of a point rough per painting, so read its line as a trend, not a measurement. The scale is relative to this archive, and a difference under half a point between two paintings is noise. Most early works exist only as phone photographs, so the two systems are kept apart and never averaged.
“I respect the engine. My p rating is not the ultimate, I am fallible too.”Peter Yuill · 2026.10.06

Each quality as a channel: its floor and its ceiling, and the day it stepped up for good. Then where the flaws were.
