“1704” Varnish Recipe

“1704” Varnish Recipe

by George Manno

Originally published in American Lutherie #12, 1987 and Big Red Book of American Lutherie Volume One, 2000



The subject of violin varnish and its making has been the topic of great debate and secrecy for the last hundred years. Many makers still spend a great deal of time chasing the elusive dream of coming up with the perfect varnish. Books and manuscripts are filled with endless recipes from the very basic to the most absurd. I have seen some formulas that call for ingredients such as goat urine, sheep bile, gold, and other even more exotic organic extracts that have to be boiled, dried, and then mixed with many different hazardous chemicals. I showed Dr. James Martin, head chemist for Bradshaw and Praeger Shellac Co., one of these more eccentric recipes. His reply to me was, “If you heat these chemicals, you will probably blow your shop to smithereens.” Needless to say, I took his advice.

The varnish recipe described on the preceding page is known throughout the world as “1704”. The recipe came out of the old Wurlitzer shop in the early ’50s. As you can see, the varnish is a simple mixture of seedlac, gum, resin, and oil mixed with alcohol.

Rosin Varnishes

Rosin Varnishes

Rosin varnishes are shunned by master violin makers because they are soft, “chippy,” and do not adhere well. Yet they are not so bad in these respects that they could not be used by an amateur or beginner on instruments with no pretension to outlast their maker. Pale rosin is a wonderful, natural, wood-derived resin that can be very easily made into a variety of beautiful and acoustically suitable varnishes both of the spirit and oil type. Its solubility in both alcohol and turpentine and its compatibility with oils and other resins make it a versatile ingredient that can help in combining normally incompatible substances to achieve special properties. Rosin varnishes have been around for centuries and in some respects they resemble those of the old Cremonese masters.

Pale rosin in powdered form can be obtained from pharmaceutical companies which use it in preparation of salves and ointments. This is the purest grade and is recommended for varnish making.

Rosin can be added to many varnishes to add body and to make them softer. Adding rosin to shellac makes a “woodcarver’s varnish” that can be prepared in just a few minutes, although it is best to let it stand overnight. This varnish brushes well, dries considerably slower than straight shellac, has good luster, and is much softer than shellac. To prepare, simply dissolve as much rosin as will go into solution in orange shellac and strain.

Oil Varnish Techniques

Oil Varnish Techniques

by David Rolfe

Originally published as Guild of American Luthiers Data Sheet #89, 1978 and in Big Red Book of American Lutherie Volume One, 2000



I decided to investigate the use of traditional oil varnishes as used by violin makers. At first sight, there seemed to be a lot of information around with enough detail to get on with the job. But as I delved deeper, I found enormous gaps in details of technique and lack of information on what is important and what is not. This is a detailed summary of what I have learned so far. My basic sources of information are the books and articles listed at the end.

Materials

Varnish. Traditional oil varnishes consist of a variety of resins, heated and dissolved in linseed oil, and turpentine. Coloring is added, and these agents can either be from the heartwood of certain trees (like dragon’s blood or gamboge) or organic mineral salts. Linseed oil is a slow-drying oil, and in conjunction with the resins, goes through the process of oxidation and polymerization (molecules of short length combine to become longer). Polymerization occurs mainly in the presence of ultraviolet light and continues for decades. Turpentine is used as a thinner or as a solvent to get the varnish on and then to evaporate in a relatively short time. The important characteristics of the varnish in liquid form are:

Review: Selected Articles from VSA Journal
Violin Society of America

Vol. VII No. 3. (All the articles in this issue were originally presented as papers at the VSA’s Tenth Annual Convention in November 1982, and include discussion based on questions from the audience.)

Peggy Shipman: “Retouching: Methods and Materials.” Ms. Shipman’s paper mentions the use of water color; choosing the right wood for repairs and possible heat treatment for same, types of stains, color theory, the use of oil vs. alcohol varnish, pigments and coloring materials, and brush types.

Herbert A. Wilson: “Space Age Technology for the Violin World.” Mr. Wilson manufactures an abrasive called “Micro-Mesh” which can be used for producing an ultra-fine finish on many surfaces including those of musical instruments. (The material is also sold on a foam backing under the name “Polysand.”) The paper deals with where, when, and how to use this material, how it acts on a surface, and how its action differs from that of other abrasives/polishing agents.

Review: Italian Violin Varnishes by George Fry

Review: Italian Violin Varnishes by George Fry

Italian Violin Varnishes
George Fry
Virtuoso Publishers, 1981
Out of print (1999)

Any book on making violin varnish, I buy. Halfway through most, I find my money would have been better spent elsewhere. Not so with this well-written conglomeration of facts, recipes, and chemical analyses.

A novice with a little experience in varnish making will be able to understand Mr. Fry’s sometimes complex theories. Mr. Fry goes into great detail explaining each and every experiment he made to obtain color, transparency, and consistency of the varnish he thought to be used 250 years ago by the great Italian masters. Unfortunately, some of the materials used in Fry’s experiments are more scarce now than when the book was first published in 1901.
