Encaustic

In Short

This technical treatise explores the "encaustic" method—a process of binding pigments with bees-wax and setting them through the application of heat. Originally prompted by Count Caylus’s fascination with the writings of Pliny, the book moves beyond mere antiquarian theory to provide a functional, reproducible system for the painter. Through detailed instructions on preparing canvases, selecting pigments, and managing the heat-fixing process, the author establishes a durable, vibrant alternative to oil painting. It remains a fascinating artifact of eighteenth-century artistic experimentation and a surprisingly practical guide for those interested in the chemistry of traditional craft.

The Story

The narrative arc of the book is essentially the journey of a scientific inquiry. It begins with the author acknowledging his role as a foreigner writing in English, humbly dedicating his efforts to a patron of the arts. He establishes the intellectual context: Count Caylus, a French scholar, had famously sought to decipher Pliny’s cryptic references to the "burnt wax" paintings of antiquity. While the academic community debated whether these ancient techniques were a form of enameling, the author rejects such pedantic confusion. He argues that the Latin urere—to burn—does not imply the fierce heat of an enamel kiln, but rather a gentle application of warmth sufficient to fuse wax and pigment.

Having cleared away these theoretical obstructions, the book transitions from history to methodology. The author recounts his own trials, describing his struggle to standardize what was once a mysterious, guarded secret. He describes the process of "dead coloring" in water-based pigments on a waxed ground, followed by the miraculous transformation that occurs when the finished work is exposed to a fire. The climax of the argument lies in the author's comparative experiments. He pits his encaustic creations against oil paintings, subjecting both to the ravages of smoke, damp, and chemical solvents. The results are decisive: the oil paintings fail, fading and cracking, while the wax-fixed colors remain vibrant and clean.

The story concludes with a shift toward the practicalities of the studio. The author provides a comprehensive guide to materials, meticulously vetting every pigment—from flake-white to bone black—to ensure they harmonize with the wax medium. He introduces a secondary application for the technique: the use of crayons. By preparing surfaces with a specific mixture of wax and chalk, artists can apply pastel-like pigments and fix them with heat, combining the ease of drawing with the permanence of painting. The book ends not with a finality, but with an invitation. The author provides a candid summary of his findings, acknowledges the limitations of his own writing, and offers to provide further guidance to any artist brave enough to set aside their oil brushes and attempt the encaustic method. It is a work that insists on the supremacy of experience over conjecture.

How It Unfolds

The intellectual foundation The author introduces the ancient mystery of "painting in wax," framing the project as an attempt to translate historical texts into modern practice. He positions his work as a rational successor to the experiments of Count Caylus.

The shift to methodology Moving from theory to the studio, the text outlines the preparation of the canvas. The author emphasizes that a clean linen cloth, thoroughly waxed on the reverse, is essential for a stable and receptive surface.

The process of execution The core of the book details the application of pigments ground in water. The author instructs the reader on how to manage tints and highlights before the final, critical step of heat-fixing.

The application of fire Detailed instructions follow on how to safely approach the canvas with a controlled heat source, such as a fire of sea-coals or a portable brazier. The author explains the precise distance and timing required to melt the wax into the canvas fibers without scorching the pigment.

The comparative trial The author documents his rigorous testing, where encaustic and oil paintings are exposed to harsh conditions. This section functions as the proof of concept, demonstrating the superior stability and washability of the wax-based method.

The extension to crayons The final technical beat covers the use of crayons on a waxed ground. This system offers a faster, more flexible alternative for the artist, essentially adapting the encaustic principles to the medium of dry media.

The People

The book is centered on the interaction between the author, Jean-Henri Müntz, and his intellectual peers. Müntz is the protagonist of this technical drama; he is pragmatic, empirical, and deeply suspicious of "conjecture." He presents himself as an outsider, both as a foreigner dealing with the English language and as a proponent of a "new" system in a world dominated by oil painting. He wants to prove that his method is not merely a historical curiosity but a professional standard that could outlast traditional techniques.

Count Caylus stands as the catalyst for the entire endeavor. While the count is not an active character in the studio, his theoretical work in the Academy of Inscriptions provides the spark that sets Müntz in motion. The count represents the scholarly, speculative side of art history, which Müntz respects but ultimately seeks to surpass through hard labor.

The "Professed Artists"—specifically those like Reynolds or Ramsey—are the silent, skeptical audience. Müntz addresses them directly, challenging them to abandon their long-practiced success in oil for the sake of an experiment. He does not view them as enemies, but as peers whose long-standing habits prevent them from seeing the inherent advantages of encaustic. By the end of the work, the reader is positioned as the final figure: an aspiring practitioner who must decide whether to trust the empirical evidence Müntz has laid out or remain committed to the status quo.

In Its Own Voice

"The colours have not that natural varnish or shining, that they acquire with oil; but you are capable of seeing the picture in any light, or in whatsoever situation you place it."

The author uses this quote from the Abbé Mazeas to explain why encaustic paintings do not suffer from the distracting, reflective glare common to oil portraits.

"It matters not if the ancients did so or not."

Müntz asserts this in response to those who would dismiss his work because it might not perfectly replicate the lost techniques of Pliny’s era, arguing that the practical value of the invention is more important than historical purity.

"In arts, one experience is worth a thousand conjectures."

The author includes this statement to defend his reliance on rigorous, repeated experiments over the abstract debates of scholars and critics.

What It's Really About

At its core, this book is an argument for the superiority of craft-based knowledge over aesthetic tradition. It asks whether the "glare" of oil varnish is truly a desirable quality or merely a crutch that obscures the natural beauty of color. By focusing on the chemical stability of wax versus the volatile nature of oil, the text questions the durability of art itself. It posits that a painting is a physical object that must survive the environment—smoke, damp, and age—and that the artist has a duty to understand the materiality of their work. Ultimately, the book is a defense of empirical observation, suggesting that the truth of a medium is found in the fire and the brush, not in academic debate.

Why Read It Today

Readers with an interest in the history of art materials or those who practice traditional painting will find this volume deeply rewarding. It provides an intimate look at the eighteenth-century artist as a laboratory scientist, carefully weighing pigments and testing the melting points of wax. The book feels like a conversation with a dedicated craftsman who is eager to share his secrets, though it does not shy away from the technical rigor required to master them.

Modern readers should be prepared for the idiosyncratic prose of an author writing in a second language; his humility regarding his "defects and improprieties of language" is charming, though it sometimes requires a careful eye to follow his technical instructions. The book is not a light, casual read; it is a serious, manual-style document that demands attention to detail. However, for those who value the tangible connection between the artist’s hand and the chemical process of creation, the book offers a rare, clear window into a lost technique. What stays with you is the author's relentless commitment to his craft—the image of him washing a test painting with soap and water just to prove that his colors will survive the test of time remains a powerful testament to his vision.
