The Guide to Utrecht Professional Artists' Materials THE GUIDE TO UTRECHT PROFESSIONAL ARTISTS' MATERIALS From the beginning Utrecht Art Supplies led the industry in promoting studio craft through tutorials, materials data and articles that made the company a valued resource for artists and educators. Included with every order from the Utrecht Linens catalog, the “Utrecht Guide” was a familiar fixture in classrooms and studios across the country. While some product formulas may have changed slightly over the years (please refer to utrechtart.com for current data), overall the Guide is as relevant today as in the 1960s. We hope this digital reprint proves as popular and useful to contemporary artists as the original was in the last century!

  • A Closer Look at Santos
    A Closer Look at Santos Objects tell us about ourselves. As we look at their style and symbolism, we can tell a great deal about the artists who made them and about the societies in which artists lived and worked. When we extend our observations by means of techniques that "see" more than the naked eye, we also expand what we can learn. Creative processes - the materials and techniques that artists chose, cultural and traditional influences - become apparent, along with physical evidence of an object's particular history. What has happened to an object may tell us about shifts in its place in society and thus about a society itself. In A Closer Look at Santos, we address other ways of looking at santos, intended for anyone interested in a long and still lively cultural tradition. Santos have been made for centuries, since the early Spanish Colonial era. In the Americas, three main traditions of artisanship - Flemish, Italian, and Spanish - contributed to a distinctly New World style, which blended local expressions and native materials with older imported styles. Today, dedicated artists in Hispanic-American communities are still creating santos, working within an evolving tradition steeped in a rich history but adapting to modern society. Santos, as objects of veneration that play an important role in religious life, lie at the very heart of the Latino cultural tradition. Specialized scientific techniques offer new ways to appreciate them and thus to celebrate some of the many threads that weave the tapestry of contemporary American culture. Seeing with Scientific Techniques In examining santos, archives of historical and anthropological literature are important sources, as are comparative studies of imagery - iconography and iconology.

  • Egg Tempera Technique
    EGG TEMPERA MISCONCEPTIONS By Koo Schadler "Egg tempera is a simple, cheap, easy-to-use technique that produced gorgeous effects...Yet nobody seems to know it." Robert Vickrey (1926-2011) There are many misconceptions regarding egg tempera, and reasons for their existence and persistence. A superficial understanding of tempera limits its potential. This handout hopes to dispel some of the myths. THE REASONS FOR MISCONCEPTIONS Reason #1: The Influence of the Renaissance Egg tempera reached its peak of popularity and achievement in the early Renaissance (approximately 1400- 1450) in Italy, and is notably associated with that time and place. Most Italian, early Renaissance paintings present a less naturalistic, more idealized rendering of the world: minimal light and shadow effects; more high-key (light) values; purer, less dirtied color; cooler color temperatures; less fully three-dimensional forms. For the most part these visual choices are not inevitable to egg tempera. Instead they reflect the less realistic, more spiritually oriented medieval perspective still present in early 1400s Italy (consequently changed by the Renaissance). Because most of these paintings were done in egg tempera, people presume the medium (rather than the culture and its thinking) accounts for this aesthetic. Misconceptions also arise from egg tempera’s association with Italian Renaissance working methods. Masters and guilds taught a successful but prescribed way of developing a painting. Its not the only way to work in tempera, but often is presented as such. Reason #2: Egg Tempera’s Disappearance Renaissance artists aspired to increasing realism in images. Oil painting has advantages (described in Misconception #7) over tempera in depicting the material world and, by the late 1400s, oil became the predominate medium of the Renaissance.

  • Adhesives and Sizes
    MATERIALS INFORMATION and TECHNICAL RESOURCES for ARTISTS - Adhesives and Sizes A “size” is a material that is applied to a support (wood, fabric, etc.) to effectively seal the surface and serve as a barrier layer between the support and the paint and ground layers. Certain materials used as size will help to prevent Support Induced Discoloration (SID), a phenomenon that occurs when water-soluble impurities in the support migrate up through the ground and paint layers. A layer of size reduces the absorbency of the support, but size should not be applied too thickly. Too thick an application can lead to problems of delamination. It is best to use either a sponge or a brush and apply an even, thin solution that effectively penetrates the surface of the support. Sizing both the back and front of wooden supports will help mitigate warping of the panel. It is generally best to also size the sides of the panel. This is even more important if the support will remain unframed or is of lesser quality wood. Fabric supports, whether adhered to a rigid panel or mounted onto a stretcher, tend to shrink once properly sized. This is especially true when an animal glue size is used. Sizing reduces the absorbency of the fibers (preventing “strikethrough” or mediums/solvents from seeping through to the back of the support), protects the canvas from the acidity of certain materials (e.g. drying oils, alkyds), and creates a taut, planar surface suitable for painting. Table (courtesy of Golden Artist Colors, Inc.) summarizing results obtained using various sizes in combination with linseed oil grounds and canvas supports.

  • GROUNDS from the Beginning of the Earliest History Of
    GROUNDS From the beginning of the earliest history of the creative arts, grounds were used in the preparation of the creative process. A ground is a first coat of paint or other preparation applied to the surface to be painted. It is designed to protect that support from dampness and atmospheric pollution as well as make a suitable surface which holds the paint. The ground gives the desired qualities of color, smoothness, rough texture, absorbency, or repellent base. The four types of commonly used grounds are oil, gesso, emulsion, and acrylic. Oil -- made by grinding pigment, then mixing with oil. Usually linseed oil or walnut oil. Gesso -- made of ground gypsum or chalk mixed with water, glue, or gelatin (which hardens as it cools) to provide a dense, brilliantly white absorbent surface for an assortment of paints. It is applied to the support's surface in several coats. The first coarse undercoat is called "gesso grasso": the final fine surface coat is known as "gesso sotile." Allowed to harden thoroughly, it is then lightly sanded. The result is surface as smooth as an egg shell. It accepts paint readily, but has enough texture to act as a slight brake, which helps the artist control the brush stroke. Emulsion -- a painting medium containing materials which will not mix (such as oil and water or water and resin), unless combined by an emulsion agent. Agents can be natural (egg yolk or milk of figs), artificial (gums or varnishes), or soponified (fatty oils or wax). Tempera is an example of an emulsion. The egg tempera is equal parts powdered pigment, egg yolk and water.

  • The Pete Swann Quick Guide to Painting with Egg Tempera
    The Pete Swann Quick Guide to Painting with Egg Tempera www.peteswann.co.uk Painting is a bit like chess - an hour to learn, a lifetime to master. Here’s a quick guide to that first hour… About egg tempera Egg tempera has a long history as a painting medium. It was widely used in ancient Egypt, Greece and the Roman world and there are many surviving examples. It involves mixing powdered pigment with egg yolk and water to make an emulsion. The paint is quite translucent and dries very quickly so it can be layered into complex compositions. The paint remains soft for a while but gradually hardens into a tough film of extraordinary durability. Egg tempera protects and preserves the support that it is painted on and tends to brighten with age. Oil paint is acidic, causes its canvas to slowly disintegrate and darkens with age. The most famous egg tempera painting is probably Boticelli’s Birth of Venus from 1485. The medium was in widespread use in medieval times and the early renaissance, particularly for religious icon paintings. Many of them survive in perfect condition due to the properties of the emulsion. After about 1500, when oil paint became widely used in Europe, the popularity of egg tempera rapidly declined. In later centuries William Blake used it, and there was a modest revival in the 20th century by Marc Chagall, Giorgio di Chirico, Mark Rothko and others. When I first tried it I worked on paper and cardboard. Later on I discovered that renaissance painters sometimes glued linen onto wooden panels and primed them thickly with gesso, sanding them down to make a smooth white surface to paint on.

  • Exposed Gesso on an Oil Painting Change Course Solely Based on Concern for Future Cleanings
    Exposed Gesso on an Oil Painting change course solely based on concern for future cleanings. Since exposed acrylic primer is more receptive to dust and contaminants, we think you might want to consider using a picture varnish that is appropriate for both oils and acrylics. This varnish should be one where resin and solvent content can be determined, so you can include this information with the painting, along with a general description which explains the surface is acrylic dispersion primer and oil paint. Documenting the materials used and sequence of application goes a long way toward ensuring the permanence of your work, and it's a great service to the collector as well. If you include that information Ask the Experts: “My paintings are done in oils, with the finished piece, a qualified conservation but there are large areas of white acrylic gesso specialist will know what to do from there. which I like to leave unpainted. Is there any reason to worry about how this will age? Will it cause problems later if the painting needs to be cleaned?” A: While we can’t speak to how a conservation professional would treat your artwork, we consider the instance of some exposed acrylic ground on an oil painting to be "within tolerances" and not a malpractice. Many, many artists include passages that are very sparsely covered or completely exposed.
