The dye pits

There is a date painted above a gate in Kano: 1498. Behind it are the dye pits, which have been in the same family ever since. What is closing them is not neglect. It is the price of a yard of cloth.

A group of workers at the Kano Dye Pits, Nigeria, 1951. Silver gelatin print by an unknown photographer. Original held in the Archives Centre, National Museums Liverpool, John Holt Collection, B/JH/PHO/470. Reproduced with permission. The caption on the reverse reads: “the pits are about 12 feet deep”.

Station 01 · The gate

Somebody painted the date on the wall.

Above the entrance to the dyeing ground at Kofar Mata, in letters that need repainting, is a year. 1498. It is not on a plaque and it is not behind glass. It is on the arch, over a gate people walk through to get to work.

The claim behind it is specific rather than vague: . His descendants still run the place, and it is the seventh generation of them who answer the phone.

Most heritage dates arrive from a government body or a tourist board. This one arrives from the family, and it has been on the wall long enough to need repainting.

1498
The year painted above the gate, and the year the family gives.
Station 02 · What is in the pit

Indigo, ash, and a month of waiting.

A dye pit is not a bucket. — we know that because somebody wrote it on the back of a photograph in 1951, and the photograph is at the top of this page.

. Then it waits: . Cloth goes in for hours, not minutes, and is lifted out periodically to drip, because the chemistry needs air as much as it needs time.

Everything about the process is slow on purpose. That is the whole of the economics of this piece, stated early.

Station 03 · Thirteen grounds

This was not a workshop. It was a sector.

It is easy to read Kofar Mata as a surviving craft. For most of its history it was closer to a works. .

Kano sat where the desert routes met the savannah, and the thing it sold was finish. Cotton could be grown in a lot of places. A deep, even, fast blue that did not wash out was harder, and the city that could do it reliably could charge for it.

The month of fermentation was never the inefficiency. It was the barrier to entry. Anybody could sell cloth. Not everybody could sell that colour.

The slowness was not a weakness in the business. For five hundred years it was the business.

Station 04 · What is left

A hundred and forty-four pits. Five working.

In 2020 the association gave a number: . In 2023, .

Two counts, three years apart, from the same people. That is not a trend line, but it is a direction, and it is the closest thing to a measurement anyone has published.

5of 144
Pits still working, on the association's own count in October 2023.
The counts do not agree

A wire report from 2007 describes thirteen pit complexes across Kano and more than a hundred pits fallen into disrepair. The association describes a hundred and forty-four pits at this one site. Those two things can both be true, or one of them can be counting something different, and we cannot tell you which.

There is no published condition survey of Kofar Mata that we have been able to find. We have asked. If one exists we will publish the number; if it does not, then the oldest working industrial site in the country is being counted by the men who work in it, from memory, for journalists who visit every few years.

Station 05 · The price of a yard

Nobody closed the pits. They were outbid.

The reasons the dyers give are not about heritage. They are about cost. . On the input side, , so the cloth to be dyed got more expensive at the same time as the finished competition got cheaper.

, which squeezes the last part of the process they still control.

Read in order, those three facts describe an ordinary commercial failure rather than a cultural one. A producer whose cost is time, competing against a producer whose cost is nothing, in a market where the buyer cannot see the difference until the colour fades.

Hidden in plain sight

The dye takes a month to come up. The cloth it loses the sale to is printed in a day and sells for about half the price. That is the entire mechanism. Kofar Mata is not being neglected to death; it is being outbid, one yard at a time, by a product that does not have to wait.

The gate still says 1498. Five pits are still warm. Whether that is survival or the last of it is a question nobody has the figures to answer, which is the reason this page exists.
