How To Tell If Piano Keys Are Ivory

Piano keys have been made from various materials throughout history, including ivory.

Ivory keys were popular in pianos manufactured before the mid-20th century but have since been replaced by synthetic materials.

Determining whether piano keys are made of ivory or a synthetic substitute can be challenging but is important for both historical and legal reasons.

In this comprehensive guide, we will explore various methods to help you identify if piano keys are made of ivory.

Visual Analysis

One of the first steps in determining if piano keys are made of ivory is to conduct a visual analysis.

Here are some aspects to consider:

Color:

Ivory keys tend to have a warm, yellowish-white color. Over time, they may develop a natural patina that adds depth and character.

Synthetic keys, on the other hand, often have a brighter and more uniform white appearance.

Grain Pattern:

Ivory keys typically exhibit subtle grain patterns that resemble the growth lines found in elephant tusks.

These lines may be more prominent under certain lighting conditions. Synthetic keys lack this organic grain pattern and appear smooth and uniformly textured.

Surface Texture:

Ivory keys possess a unique texture that is smooth but not as slippery as synthetic materials.

They often have a slightly porous surface that can absorb moisture from fingertips, resulting in a more tactile feel.

Conversely, synthetic keys tend to have a smoother and sometimes slightly glossy surface.

Acoustic Analysis

Another method to determine if piano keys are made of ivory is through acoustic analysis.

Different materials produce distinct sonic characteristics, and trained ears can detect these differences.

Here are some aspects to consider:

Sound Quality:

Ivory keys are known to produce a warm and resonant tone with a rich timbre. They offer a degree of natural dampening that enhances the subtleties of piano playing.

Synthetic keys, while capable of producing good sound, often lack the same depth and warmth.

Key Responsiveness:

Ivory keys have a unique responsiveness that allows for more nuanced control over dynamics and touch. They offer a tactile feedback that many pianists find favorable.

Synthetic keys may feel slightly different under the fingers, often with a smoother but less responsive touch.

Expert Opinion

Consulting with an expert can greatly assist in determining whether piano keys are made of ivory.

The expertise of a piano technician or appraiser can provide valuable insights based on their knowledge and experience.

They can examine the keys and consider factors such as age, piano make and model, historical context, and manufacturing techniques used during a particular era.

Legal Considerations

The trade and sale of ivory have been heavily regulated due to conservation efforts and concerns regarding animal welfare.

It is essential to be aware of and comply with legal restrictions when dealing with pianos containing ivory keys.

Laws vary by country, so it is wise to consult local regulations or seek professional guidance to ensure compliance.

Chemical Analysis

In addition to visual and acoustic analysis, chemical analysis can provide further insights into the composition of piano keys.

Although this method requires specialized equipment and expertise, it can offer definitive results.

Here are some techniques used in chemical analysis:

Microscopic Examination:

Microscopic examination involves analyzing small samples of the piano keys under a microscope.

This allows experts to observe the structure and composition of the material at a microscopic level.

Ivory keys may exhibit distinctive characteristics such as Haversian canals or Schreger lines, which are not present in synthetic substitutes.

Fourier Transform Infrared Spectroscopy (FTIR):

FTIR is a technique used to analyze the molecular composition of a material.

By shining infrared light on a sample, it produces a unique spectrum that can be compared against known spectra to identify the material.

Ivory has a characteristic spectrum due to its molecular structure, allowing for differentiation from synthetic alternatives.

X-ray Fluorescence (XRF):

XRF is a non-destructive technique that can determine the elemental composition of a material.

It works by irradiating the sample with X-rays, causing the atoms in the material to emit characteristic fluorescent X-rays.

By analyzing the emitted X-rays, experts can determine the presence of specific elements, such as calcium and phosphorus, which are found in ivory but not in synthetic materials.

Historical Context

Understanding the historical context of piano manufacturing can also provide valuable clues when identifying ivory keys.

During certain periods, such as the late 19th and early 20th centuries, ivory was commonly used due to its availability and desirable properties.

Piano brands known for their use of ivory keys during these eras include Steinway & Sons, Bösendorfer, and Bechstein.

Researching the history of a particular piano model or consulting vintage piano catalogs can help establish the likelihood of ivory keys.

Environmental Considerations

Apart from legal restrictions, it is worth considering the ethical and environmental implications of ivory.

Due to the conservation efforts surrounding endangered species, it is generally not recommended to trade or purchase pianos with ivory keys unless they are antique or hold historical significance.

Synthetic key replacements are widely available today, offering a sustainable and responsible alternative for piano restoration.

Conservation and Preservation

Preserving ivory keys, whether they are part of an antique piano or a historical instrument, requires special care to prevent damage and deterioration.

Here are some considerations for conserving and maintaining ivory keys:

Humidity Control:

Ivory is sensitive to fluctuations in humidity, which can cause it to shrink or expand. Maintaining a stable humidity level in the piano's environment, ideally between 40% and 60%, can help prevent warping or cracking of the ivory keys.

Cleaning and Polishing:

Regular cleaning and polishing of ivory keys can help maintain their appearance and prolong their lifespan.

It is important to use gentle cleaning agents specifically designed for ivory, as harsh chemicals can damage the material.

Soft, lint-free cloths should be used for cleaning, and excess moisture should be avoided to prevent absorption by the ivory.

Protection from UV Light:

Excessive exposure to sunlight and ultraviolet (UV) radiation can cause ivory to yellow and deteriorate.

Positioning the piano away from direct sunlight or using window treatments to block UV rays can help protect the ivory keys.

Additionally, covering the keys when the piano is not in use can provide additional shielding.

Professional Restoration:

If ivory keys show signs of damage or wear, professional restoration may be necessary.

A skilled piano technician or conservator experienced in working with ivory can repair cracks, restore lost patina, and address any other issues to bring the keys back to their original condition.

It is important to choose a reputable professional with expertise in working with ivory.

Synthetic Substitutes

Due to the regulations surrounding the trade of ivory and the ethical concerns associated with it, the piano industry has shifted towards using synthetic substitutes for key materials.

These alternatives aim to mimic the appearance, feel, and acoustic properties of ivory while providing a sustainable and legal option.

Some common synthetic materials used for piano keys include:

  • Acrylic: Acrylic-based materials offer durability and good resistance to wear. They can be manufactured to closely resemble the appearance of ivory and provide a similar tactile experience.

  • Mineral Composite: Mineral composite materials combine mineral powders with resin to create a key material that replicates the look and feel of ivory. These materials are often used in high-quality digital pianos.

  • Cellulose-Based Plastics: Certain cellulose-based plastics, such as celluloid or ivorite, have been used as synthetic substitutes for ivory. These materials can be molded to shape and can exhibit properties similar to ivory keys.

The Value of Ivory Keys

Pianos with original ivory keys, especially those from renowned manufacturers or particular eras, can hold historical and sentimental value.

Some collectors and enthusiasts appreciate the authenticity and unique characteristics of ivory keys, contributing to their desirability.

However, it is essential to navigate the legal landscape and ethical considerations surrounding ivory trade before engaging in any sale or purchase.
