The image shows three items placed against a neutral, dark-gray background:

  1. Left Item: A small clear glass jar with a black lid containing a fine white powder labeled "PLASTER OF PARIS / Calcium sulphate / (Gypsum) / RJG." There is a handwritten numerical marking "168" near the bottom of the jar.

  2. Center Item: A rectangular sample with two distinct sections made of plaster of Paris. The upper section appears smooth and bright white, labeled "above - size," while the lower section is slightly textured and stained with a yellowish-brown tint, labeled "below - linseed oil." The text description is printed on a beige label at the base of the rectangle.

  3. Right Item: A small ruler-like scale chart, serving as a measurement reference, marked with gradations and numbers.

This setup seems to be a scientific or material-testing display used to demonstrate how plaster of Paris interacts with size and linseed oil.

The image shows a comparative display of materials associated with plaster of Paris. On the left, there is a small transparent glass jar with a black cap containing a white powder labeled "PLASTER OF PARIS Calcium sulphate (Gypsum) RJG" on a beige paper label wrapped around it. The jar is numbered "168" in black on the lower part.

In the center, there is a rectangular board that is divided into two sections. The top section of the board is white with a textured surface, while the lower section has a yellowish tint. Below this, a label reads: "PLASTER OF PARIS above - size below - linseed oil," indicating that the top section of the board is treated with size and the bottom section with linseed oil.

On the right side of the image is a ruler with grayscale bars, marked with numbers from 0 to 3 and increasing by increments of 10, which serves as a scale reference for the objects. The background of the image is a plain grey.

Here's a description of the image:

Overall Composition:

The image is a still-life composition against a neutral gray background. It features a glass jar containing a white powder, a rectangular block of material, and a small color calibration strip. The lighting is even, creating a well-lit and clear presentation of the objects.

Objects and Details:

  • Glass Jar: On the left is a clear glass jar with a black lid. It's filled with a white powder, likely "Plaster of Paris" or calcium sulfate, and has a label wrapped around it that provides information: "LASTER OF PARJS," "Calcium sulphate (Gypsum)," and "RJG". A number "168" is visible on the bottom of the jar.
  • Rectangular Block: To the right of the jar is a rectangular block, presumably made of the same powder. The top portion of the block is a pristine white color. The bottom section of the block is a darker, yellowish color and is labeled "Plaster of Paris," "above - size," and "below - linseed oil" which indicates it may have been treated with something.
  • Color Calibration Strip: Next to the rectangular block is a small gray and white color strip used for color correction.

Subject Matter and Likely Purpose:

The image seems to be a scientific or educational shot illustrating the properties or characteristics of the powder material used in plaster of Paris. The two sections of the rectangular block illustrate the impact of a treatment such as size or linseed oil.

Here is a description of the image:

The image shows three objects: a jar of plaster of Paris, a block of plaster of Paris with a coating, and a gray scale ruler. All items are resting on a gray surface.

The jar is glass with a black lid, and it is about half full of white powder. A tan label is affixed to the jar, reading "LASTER OF PARJS" at the top, followed by "Calcium sulphate (Gypsum) RJG". Below the jar, the number "168" is written on the glass in white.

To the right of the jar is a rectangular block. The lower third of the block is covered in a tan paper label that reads "PLASTER OF PARIS" at the top, with "above - size" and "below - linseed oil" below it. The middle third of the block has a tan, oily appearance, and the top third of the block is a smooth, matte white.

To the right of the block is a gray scale ruler.

The image depicts a demonstration of Plaster of Paris, which is a type of plaster made from gypsum (calcium sulphate). The setup includes three main components:

  1. Jar of Plaster of Paris:

    • The jar contains a white powder labeled "PLASTER OF PARIS" and "Calcium sulphate (Gypsum) RJG". The label indicates that the jar contains calcium sulphate, which is the primary component of Plaster of Paris.
  2. Plaster Sample:

    • A rectangular sample of Plaster of Paris is shown, divided into two sections:
      • The upper section is white and labeled "above - size". This section appears to be the dried and hardened form of Plaster of Paris.
      • The lower section is yellowish-brown and labeled "below - linseed oil". This section shows the effect of linseed oil on the plaster, which seems to have altered its color and texture.
  3. Scale:

    • A small ruler or scale is placed next to the plaster sample for size reference. The scale has markings in centimeters, providing a sense of the dimensions of the plaster sample.

Overall, the image illustrates the appearance and properties of Plaster of Paris in its powder form and its hardened state, as well as the effect of linseed oil on the plaster.
