Lacquerware is a traditional craft that involves applying layers of lacquer—made from the sap of the Toxicodendron vernicifluum tree—over carved wooden items, metal, glass, fabrics, and even plastics. While lacquer is often associated with Japanese lacquerware, it is also used in other cultures, such as Russia, where it is applied to boxes. Telling lacquer from plastic can be challenging, but some key differences can help with identification. For instance, lacquerware tends to have a depth of field achieved by layering applications of lacquer, while plastic may show seams or joints. The weight of an object can also be a clue, as papier-mâché, a common material in lacquerware, is usually lighter than plastic of the same size and thickness. The sound of a gentle tap can also be indicative, with plastic giving off a louder, sharper click compared to the muted sound of papier-mâché.
Characteristics to tell lacquer from plastic
| Characteristics | Values |
|---|---|
| Application | Lacquer is applied to carved wooden items, but can also be used on metal, glass, fabric, and plastic. |
| Composition | Lacquer is made from the sap of the Toxicodendron vernicifluum tree, which contains urushiol, the same compound found in poison ivy and oak. Plastic is a synthetic material made from polymers. |
| Appearance | Lacquer has a distinctive depth of field achieved by layering applications of paint. Plastic has a more uniform appearance. |
| Texture | Lacquer has a smooth, glossy texture. Plastic can vary in texture depending on the type, but is often smooth as well. |
| Weight | Lacquerware is typically heavier than plastic items of similar size. |
| Sound | When tapped, lacquerware produces a muted sound, while plastic gives off a louder "click". |
| Reaction to Solvents | Lacquer thinner tends to melt plastic. Some plastics that are more resistant to lacquer thinner include PVC, polyester, and acetal. |
| Allergenicity | Lacquer can cause severe rashes and allergic reactions due to the presence of urushiol. Plastic is less likely to cause allergic reactions. |

Weight: Papier-mâché is lighter than wood, plastic, or argillite
When it comes to distinguishing lacquer from plastic, one of the key indicators is the weight of the object in question. Papier-mâché , a versatile material with a rich history, is known for being lighter than wood, plastic, or argillite.
Papier-mâché has been used for centuries to create a wide range of items, from nativity figures and decorative panels to functional objects like trays and chair backs. Its lightweight nature has been particularly advantageous in certain applications, such as the construction of lightweight domes for observatories in the 19th and early 20th centuries. These domes needed to be light enough to be easily rotated for telescope positioning.
The weight difference between papier-mâché and other materials like wood, plastic, or argillite can be quite noticeable. This is due in part to the construction of papier-mâché, which typically involves layering paper and glue or paste over a base form. The paper used can vary, from newspaper to brown paper, and the number of layers can be adjusted to achieve the desired thickness and strength.
Additionally, the base form or core of a papier-mâché object can impact its weight. While some creations may be hollow, others might have a solid core made of materials like wire mesh, a balloon, or wadded-up newspaper. This core provides support while the papier-mâché dries, ensuring the desired shape is maintained.
The lightweight nature of papier-mâché is one of its defining characteristics and can be a crucial factor in its selection for certain applications. However, it's important to note that the weight of a finished papier-mâché piece will also depend on factors such as size, wall thickness, and overall construction.

Sound: Wood sounds sharp, plastic gives off a loud click, and papier-mâché sounds muted
When trying to distinguish between lacquer, wood, plastic, and papier-mâché, one of the key indicators is the sound the material produces when gently tapped.
Wooden objects, for example, will generally emit a sharp or harsh tone when struck. This is due to the natural resonance of the wood, which can vary depending on factors such as the type of wood, grain pattern, and moisture content.
Plastic, on the other hand, tends to produce a loud and distinct "click" when tapped. This is because plastic is often a more rigid and less resonant material than wood. The sound of plastic can also vary depending on its thickness and the type of plastic used, with some plastics having a higher pitch or a duller tone than others.
Papier-mâché, being a lightweight and porous material, will typically produce a muted and dampened sound when tapped. This is because the paper fibres absorb and dampen the vibrations, resulting in a softer and less resonant sound compared to wood or plastic.
Lacquer, a natural coating often applied to wood, can also affect the sound of an object. Lacquer can add a layer of protection and shine to wooden surfaces, and it dries to form a hard and durable finish. However, the sound of lacquered wood may not be significantly different from untreated wood, as the lacquer is typically applied in thin layers. The sound may depend on the thickness of the lacquer and the number of coats applied.
It is worth noting that the sound of these materials can also be affected by other factors, such as the size and shape of the object, the temperature, and the presence of any additional coatings or treatments. Therefore, while sound can be a helpful indicator, it may not always be definitive in determining the material.

Texture: Real papier-mâché has a depth of field, achieved by layering paint and lacquer
Real papier-mâché is formed with very few actual joints and has a depth of field, achieved by layering paint and lacquer. This technique is not only used in papier-mâché but also in paintings to capture a rich depth and atmosphere. Layering paint involves applying one layer over another until the final effect is achieved. This makes it easier to add surface texture, subtle colour shifts, and depth. Layering techniques differ depending on the painting medium used. For instance, if the paint is transparent, adding a small amount of white can make it opaque. On the other hand, if the paint is opaque and you want to make it transparent, you can add any clear medium or clear gel.
Additionally, the right amount of blending can add richness and complexity to the artwork. Masking, for example, allows you to create layered and intricate designs by covering parts of your painting. This gives you precise control over where your layers are visible, enabling you to refine details and make seamless adjustments without altering the layer beneath. You can also adjust the colour and contrast of layers to simulate how distant objects appear fainter and cooler in colour. This technique, called atmospheric perspective, is particularly effective in landscape paintings, adding a sense of depth and distance.
Watercolour lifting is another technique that involves applying layers of watercolour and then removing or blotting specific sections of the paint to reveal the layers beneath. This technique is often used to create highlights. Similarly, sgraffito involves scratching or scraping through a layer of wet paint to reveal the layers beneath, creating intricate textures or accentuating particular areas.

Visuals: Examine for a grid pattern, cutouts, or tiny dots that make up a photo decoupage
When trying to distinguish lacquer from plastic, one of the key things to look out for is the presence of a grid pattern, cutouts, or tiny dots that make up a photo decoupage.
Firstly, when examining the piece, look for a grid pattern on the bottom or sides. This could indicate a machine-pressed argillite or argalite box, which is a sign of a fake lacquer box. Authentic lacquer boxes should not have seams that show, as real papier-mâché is formed with very few actual joints.
Secondly, use a magnifying glass to closely examine the piece for cutouts and tiny dots that could indicate a photo decoupage. These are telltale signs of fake lacquer boxes, which often use decoupage techniques.
Additionally, consider the weight of the box. Papier-mâché, which is commonly used in authentic lacquer boxes, is usually lighter than wood or pressed argillite/argalite of the same size and wall thickness. So, a heavier box could be an indication of a fake lacquer box.
Finally, gently tap the box with your fingernail or close the lid to listen for a distinct sound. Wood boxes produce a "sharp" or "harsh" sound, while plastic or argillite/argalite boxes give off a louder "click" when tapped. Authentic lacquer boxes made of papier-mâché will have a muted and dampened sound.
While these visual cues can be helpful, it is important to remember that distinguishing lacquer from plastic may not always be absolutely certain. The reliability of your supplier and the presence of marks and signatures can also provide valuable clues.

Material: Lacquerware is applied to carved wooden items, but can also be used on metal, glass, fabric, and plastic
Lacquerware is typically applied to carved wooden items, but it can also be used on other materials, such as metal, glass, fabric, and plastic. Lacquer can be applied to a variety of surfaces to enhance and protect the finish. When applied to wood, it provides a glossy and durable coating that preserves the item.
On metal surfaces, a clear lacquer finish can be used to protect the material from corrosion and enhance its appearance. It is important to follow the correct application procedure to ensure a successful result. This includes cleaning the metal surface with acetone to remove any residue and ensuring a dust-free environment during the spraying process.
Lacquer can also be applied to glass to increase the longevity of the item. Clear coat lacquers are often used for this purpose, providing protection from UV light, dirt, and external factors such as salt air or pollution, which can cause fading or chalking over time.
Plastic items can also benefit from lacquer application. Clear coat lacquers are suitable for use on plastic and can enhance the durability of the item, especially in external conditions. It is recommended to use a spray application method for plastic items to achieve an even finish.
Additionally, lacquer can be applied to fabric to create a unique effect. While it is less common to use lacquer on fabric, it can be done to create a stiffened or waterproof surface, although this may require specific products and techniques. Overall, lacquerware is a versatile technique that can be applied to a range of materials with the proper methods and precautions.

Frequently asked questions
Lacquer is mainly applied to carved wooden items, but it can also be used on metal, glass, fabrics, and plastics. Plastic, on the other hand, is commonly used to create thin sheets or coatings.
Some well-known types of lacquerware include Negoro Urushi, Tsugaru-nuri, Wajima-nuri, and Johana Urushi. Negoro Urushi, for example, involves painting items with black lacquer and then layering them with red, resulting in a distinctive black area over time.
Authentic lacquer boxes have a depth of field achieved by layering multiple applications of paint and lacquer. They should not have visible seams or "cutouts," and the bottom or sides may reveal a telltale "grid pattern." The weight and sound of the box when tapped can also help distinguish it from plastic or other materials.
PVC is mentioned as a plastic that can resist lacquer thinner without being as susceptible to solvent stress cracks. Nylon is not recommended due to its moisture absorption and expansion/contraction properties, which can cause cracking in the lacquer.
Plastics can be electroplated using various methods, such as treating with electroless nickel or cupramonium hydroxide solutions. However, these chemicals can sometimes attack the surface of the plastics, and the expansion and contraction of certain plastics like nylon can affect the lacquer coating.
