Pigments for Fresco Painting - Part I

There have been another one hundred and thirteen posts in a previous Art Resource series that have focused on the following topics:
(i) Units used in dyeing and printing of fabrics;
(ii) Occupational, health & safety issues in an art studio;
(iii) Color theories and color schemes;
(iv) Optical properties of fiber materials;
(v) General properties of fiber polymers and fibers - Part I to Part V;
(vi) Protein fibers;
(vii) Natural and man-made cellulosic fibers;
(viii) Fiber blends and melt spun fibers;
(ix) Fabric construction;
(x) Techniques and woven fibers;
(xi) Basic and figured weaves;
(xii) Pile, woven and knot pile fabrics;
(xiii) Durable press and wash-and-wear finishes;
(xvi) Classification of dyes and dye blends;
(xv) The general theory of printing.

To access any of the above resources, please click on the following link - Units Used in Dyeing and Printing of Fabrics. This link will highlight all of the one hundred and thirteen posts in the previous a are eight data bases on this blogspot, namely, the Glossary of Cultural and Architectural Terms, Timelines of Fabrics, Dyes and Other Stuff, A Fashion Data Base, the Glossary of Colors, Dyes, Inks, Pigments and Resins, the Glossary of Fabrics, Fibers, Finishes, Garments and Yarns, Glossary of Art, Artists, Art Motifs and Art Movements, Glossary of Paper, Photography, Printing, Prints and Publication Terms and the Glossary of Scientific Terms. All data bases in the future will be updated from time-to-time.

If you find any post on this blog site useful, you can save it or copy and paste it into your own "Word" document for your future reference. For example, Safari allows you to save a post (e.g. click on "File", click on "Print" and release, click on "PDF" and then click on "Save As" and release - and a PDF should appear where you have stored it). Safari also allows you to mail a post to a friend (click on "File", and then point cursor to "Mail Contents On This Page" and release). Either way, this or other posts on this site may be a useful Art Resource for you.

The new Art Resource series will be the first post in each calendar month. Remember - these Art Resource posts span information that will be useful for a home hobbyist to that required by a final year University Fine-Art student and so undoubtedly, some parts of any Art Resource post may appear far too technical for your needs (skip those mind boggling parts) and in other parts, it may be too simplistic with respect to your level of knowledge (ditto the skip). The trade-off between these two extremes will mean that Art Resource posts will be hopefully useful in parts to most, but unfortunately may not be satisfying to all!


Pigments for Fresco Painting - Part I
There is a lack of modern scientific and technical studies directly related to artists' materials; much carefully controlled research remains to be done to bring our data on fresco colors up to date.

The fresco palette is more restricted than any of the others; the pigments must not only be absolutely light proof, but must resist the alkaline action of lime plaster and the acid action in the polluted air. Pigments must be free from soluble salts and any impurities that are likely to react with acids or alkalis. When selecting pigments, attention should be given to the brilliance and purity of tone in the dry state, which is approximately, if not exactly, the same as the finished fresco effect.
