Sizing Paper and Gelatin Sizing

6/10/2013 12:14 AM

European PapermakingUnsized paper is called “waterleaf” paper. It is usually composed of cellulose fibers that are hydrophilic, meaning they ‘love water.’ This is an advantageous quality while paper is being made, but can lead to unfortunate consequences once the paper is made. The extreme porosity of an untreated sheet of paper means that printing or drawing inks and water-based paints will soak into the paper spreading quickly and randomly. This is called ‘bleedthrough.’ Sizing retards some of paper’s absorbency.

MY FIRST INTRODUCTION to the art of fresco was at a very young age, when I was taken to the Detroit Institute of Art and exposed to the Detroit Industry Murals by Diego Rivera. I'll never forget the awe and excitement I felt as I walked through the gates to the courtyard where the murals live. I still feel it today — on every visit. It wasn't until many years later that my wife and I had the pleasure of meeting two people who worked as apprentices on these murals under Rivera, Lucienne Bloch and Stephen Pope Dimitroff. It was through their generosity and tutorage that we embarked on a journey to become fresco artists. We have found that learning the day-to-day workings has only increased our excitement and awe for the work that has been done before us. The present article will supply a brief history on fresco and enough instruction to enable the reader to feel this same excitement.

Water or Bole Gilding

6/2/2013 9:45 PM

Gilding is an art that requires dexterity, savoir-faire and skill, qualities that craftsmen obtain after years of experience. There are two basic techniques in applying gold or metal leaf to surfaces: oil and water gilding. Both techniques employ a glue to adhere the leaf to the substrate, but the difference lies in the type of glue. This technique uses a water-based glue or size.

Harley holds the views that the use of the English word pink referred to a pseudo-lake pigment, differentiating it from lake pigments, for which the English word lake described. In some of the treatises cited in my earlier post, they describe depositing the dye on alum (aluminum sulfate postash) or chalk (calcium carbonate). This is different from the process used to make lake pigments where the dye is precipitated on freshly made aluminum hydroxide. Interestingly, aluminum hydroxide is made by dissolving alum or aluminum sulfate in water and then precipitating it in a chemical reaction with an alkali, such as soda ash (sodium carbonate) or pearl ash (potassium carbonate), by adding this alkali dissolved in water to the first solution. Aluminum hydroxide precipitates from the solution as a powder, gel or horny mass, depending upon the temperature and pH of the solutions. This procedure is quite different from that outlined in the treatises for making Dutch pink.
