Colour of South Drawing Room: Turner's patent yellow

"Patent yellow, also known as Turner's yellow (PbC12. 5-7PbO) was patented by James Turner of England in February 1781, hence its name. Turner noted Scheele's discovery as applicable for, "a method of producing a yellow colour for painting in oil or water, making white lead, and of separating the mineral alkali from common salt, all to be performed in one single process" (Harley 1970, 91-92). The yellow pigment was made by grinding together, in water, two parts of lead (either red lead or litharge) and one part of sea salt. The mixture was allowed to stand for twenty-four hours. A caustic soda solution was poured off and the remaining white substance was heated (and dried) until it reached the desired shade of yellow.

Turner's patent did not prevent other manufacturers from copying his process. He sued one competitor and won the case on appeal in 1787. The case was published in books on patent law because it was won on a ruling that stated that if a patentee claimed to do several things by one process and one failed; the whole patent was void. In fact, Turner had listed several different names for lead and for the type of salt that could be used. Turner's competitor could not prove definitively that variations in the raw materials would not produce the pigment and Turner retained his patent.

A statute ordered by an Act of Parliament extended the time allowed to Turner as the sole manufacturer because competitors had taken his rightful income. It went on to state that Turner's yellow was superior and less costly than orpiment. It contributed to the National income of England and to the salt tax in that it was made from native raw materials.

Turner's yellow was widely used in England and regarded as durable and bright. It was sold at one shilling per watercolor cake in spite of a known tendency to blacken. Field claimed that it worked well in both oil and watercolor but noted its impermanence in sunlight.

In spite of the introduction of more permanent yellows in the nineteenth century, it was produced on a large scale. C. T. Kingzett, author of The History, Products and Processes of the Alkali Trade, 1877, recorded its production at a soda factory at Walker-upon-Tyne, England, where it was sold as Turner's Patent Yellow. At the Great Exhibition of 1851, an example of its use in oil was provided by the Washington Chemical Company of Washington, Durham, England (Harley 1970, 91-92)."

Still need to find somewhere to stock it. Can buy here (ebay).
Think this is the Green paint in the Loggia though.

Steps

These are the measurements and general construction of the base for the steps (to be tested and adjusted as it is being built)

There might be some changes depending on the layer of reinforcement at the base of the frame (gravel or concrete) and interference with the plywood base of our opening



PS: Sorry small error on sketch, full height of lower step should be 200 not 400

Couldn't really find better photos/website. This installation at Keilder used machine-folded steel. I like the articulated joints.

Gordon Pask Quote

It is clear that an aesthetically potent environment should have the following attributes:

1. It must have sufficient variety to provide the potentially controllable novelty required by a man (however, it not swamp him with variety - if it did, the environment would merely be unintelligible).
2. It must contain forms that a man can interpret or learn to interpret at various levels of abstraction.
3. It must provide cues or tacitly stated instructions to guide the learning and abstractive process.
4. It may, in addition, respond to a man, engage him in conversation and adapt its characteristics to the prevailing mode of discourse.

Retreating Village, Happisburgh

The cliff-top village of Happisburgh in Norfolk is falling into the sea. a retreating village is deployed in the disintegrating territory between the sea and the land. It adopts an architectural language of impermanence, of permeable screens, loose-fit structures that complement and contribute to the nature of the restless landscape.

This is how we should run our installation!

This is a description of a device used by artists in Soane's time to make images look more picturesque. Pretty cool.

Really similar to one part of the Privacy Device.

Look here for more optical devices from that period. Nice aesthetic (if a bit cliched).

This website has quite a few interesting old viewing devices.

Privacy Device

Privacy Achieved

Design so far...

Hi,


These are the design process of the privacy device.

Your head and arms go inside the device, so that your actions are not visible to others. Then you fiddle with a curtain-like screen so you can spy on others without being watched. Then someone comes (next guest) and opens the screen from the outside, intruding into your privacy and ruining your "moment".

A small idea for what installation could do.

drawers open to frame a view

which slides to reveal a memory

which flips to reveal a reflection

which swings to reveal a relationship

which folds to reveal a narrative

which lifts to reveal your own position

John Huston American Director 1906-1987.

"You walk through a series of arches, so to speak, and then, presently, at the end of a corridor, a door opens and you see backward through time, and you feel the flow of time, and realize you are only part of a great nameless procession."
