Shellac is an all purpose sealant and finish that is durable, time tested, and so non-toxic it is edible. It is environmentally friendly, renewable, and capable of incredibly deep rich finishes that are organically and aesthetically compatible with all woods. It can be used alone, with traditional natural finishes and coatings, and with modern synthetic mixtures.
Shellac consists of a resin which is the secretion of the female lac beetle and the solvent ethyl alcohol. The lac beetle (Laccifer Lacca) is found in southwest Asia, primarily India. The beetles feed on the tree sap of three specific trees: Palash, Kusum, and Ber or Indian Plum. During the life and egg lying cycles of the female beetle lac is secreted to protect the beetle and the eggs. The branches are then harvested and the lac resin scraped off. This is called sticklac and at this stage it is still very impure with a lot of contaminants and debris.

The method is very labor intensive, requires drying between layers, is very tricky to master, and has about as many recipes, methods, and tricks as there are French polishers.

In the spring of 2013, I was contacted by the Mystic Seaport Museum. I had been a Conservation Fellow there in 2000 and worked under the direction of then Curator, William Peterson and Conservator, David Matthieson. My old friend and colleague Christopher White (then Collections Manager) had a request for me. “Would you be interested in conserving the Narwhal Hall Tree?” My first reaction was: “Yes, of course I would”. It is one of the most unusual and cherished pieces of maritime history and I certainly knew the piece since I walked past it in storage many times. Saying yes was the easy part of the project, what laid ahead was the conservation of an object that would take me on a journey of a lifetime.
The hall tree was said to be made by Capt. John O. Spicer of Groton, Connecticut on the Whaling Bark Nile in the second half of the 19th century. The hall tree came into the museum’s collection in 1964. It had descended in the Spicer family and had one other owner before it arrived at the Seaport. After I had accepted the challenge, an account was discovered in the museum’s archives written by Capt. Spicer detailing the story and fabrication of the hall tree. Capt. Spicer states that wood came from the Sandwich Islands and is called “Man-ne-ta wood”. The letter is a fascinating account, rich with fanciful tales of his whaling expedition and his account of how he captures the narwhal with the large tusk. More >>

Cooper Technica, Inc.
My company, Cooper Technica, Inc., has been privileged to work on some of the greatest automobiles ever made. At our workshops in Chicago, Illinois and in Lyon, France, we restore rare and valuable vintage European cars from the 1930s and 1940s. These specially selected cars embody the best of pre-WWII creativity and engineering genius.
Because these cars are an important historical record, collectors and restorers share the responsibility to preserve these cars as much as possible in their original condition. Often the best option is to do a mechanical restoration only, and leave the body in its ‘as found’ state. However, some cars are too far gone to leave it ‘as found’. Either the deterioration is too extensive, or previous attempts at restoration destroyed or lost original components. For these cars, the question is, how to restore them to preserve as much of the original car as possible, and also to insure that the restored car is accurate and authentic to the original.
To achieve the highest degree of authenticity and originality, we must be more than restorers; we must be meticulous automotive historians and dauntless forensic sleuths.
Why? Because we cannot bring a car back to original without knowing what original was. We must learn how the car came to be in its current condition and configuration.

AIC Annual Meeting, Miami, FL
This 2-day pre-session is intended for a range of practitioners from specialties spanning architecture, objects, and paintings, from those with little or no experience to expert laser users.
On Tuesday, May 12 participants will learn about the various types of lasers available, safety, and how lasers have been used in the treatment of cultural property. Protocols for determining safe working parameters for different materials will be discussed, along with some of the most important current research on damage parameters. Several lasers will be available for demonstrations.
On Wednesday, May 13 participants will divide into smaller groups for practical, hands-on demonstrations and experience. A field trip will also be offered for those interested in cleaning of exterior architectural surfaces.

AIC Annual Meeting, Miami, FL
This two day, hands-on workshop is specially designed to introduce and broaden the conservation professional’s exposure to the range of materials, technical skills, and processes available while using an airbrush. Practical conservation applications and materials use will be explored, along with details on airbrush set-up, usage, trouble shooting, accessories, and maintenance. Emphasis will be placed on proper tool handling techniques and form. The range of projects will progress from basic operation, skill drills, masking and frisket methods, and freehand spraying, before moving on to advanced airbrush techniques. The Iwata airbrushes will be available for optional purchase after the workshop at significantly discounted prices.
