| Welsh Color & Conservation, Inc. specializes in analytical and consulting services for a number of areas. We offer expertise in the research and analysis of all types of paint, and wallpaper finishes for the architect, engineer, curator, historic site administrator, contractor and homeowner. |
| |
| Typically, we visit the building to conduct an overall investigation and sampling of the interior and/or exterior. In this approach, the most thorough and accurate evaluation of historic finishes can be accomplished. However, for those who need only a few samples analyzed and do not require our expertise for an on-site investigation, you can take your own samples to send to us for microscopical analysis. For such projects, our publication, the Paintpamphlet™, which is a "how-to" booklet, gives detailed and illustrated instructions on investigation and sampling procedures. |

| Laboratory analysis is done with stereo, polarized light and/or scanning electron microscopes and spectrophotometers to assess and identify: |
