Historic Paint Analysis - Report Preparation

Report Preparation

Following the microscopic investigation a report is written. There are a variety of report types. Some analysts simply summarize their findings and provide little or no discussion of the individual samples and provide only their conclusions regarding historic finishes. At the other end of the spectrum are those who provide not only a discussion of each, individual sample, but also Munsell colors for each layer of each sample. This enables the clients to reach their own conclusions. In many cases the clients have access to additional information such as the history of the building and its maintenance which is not available to the finishes analyst.

Some analysts also provide photomicroscopy as part of their reports. Photomicroscopy is the photography of the samples through the microscope. Its advantage is to illustrate the findings of the report. Disadvantages include color distortions created by the light source and photographic dyes and also the tendency for some clients to match the colors observed in the photographs, rather than those provided in the report itself.

Following the basic report, further research may be required. Typical research includes the following:

  • Provision of color sheets of selected colors from the Munsell Color System.
  • Matching of the Munsell colors to a paint manufacturer's system.
  • Pigment testing, such as for lead content.
  • Media testing, such as for linseed oil or latex.
  • Testing of clear or translucent finishes such as varnishes and shellacs.
  • Further investigation of decorative painting such as graining (imitating wood), marbelizing (imitating marble), stencilling, or murals.
  • Consultation in the replication of historic finishes.

Famous quotes containing the words report and/or preparation:

    Men are born to write. The gardener saves every slip, and seed, and peach-stone: his vocation is to be a planter of plants. Not less does the writer attend his affair. Whatever he beholds or experiences, comes to him as a model, and sits for its picture. He counts it all nonsense that they say, that some things are undescribable. He believes that all that can be thought can be written, first or last; and he would report the Holy Ghost, or attempt it.
    Ralph Waldo Emerson (1803–1882)

    With memory set smarting like a reopened wound, a man’s past is not simply a dead history, an outworn preparation of the present: it is not a repented error shaken loose from the life: it is a still quivering part of himself, bringing shudders and bitter flavours and the tinglings of a merited shame.
    George Eliot [Mary Ann (or Marian)
