What is Sonication? – A Complete Guide for Jewellers

Introduction

In the jewellery industry, maintaining the shine and brilliance of ornaments is essential. Traditional cleaning methods like cloth polishing or brushing often fail to reach tiny engravings, stone settings, and hidden areas. That’s where sonication or ultrasonic cleaning comes in. By using high-frequency sound waves in a liquid solution, jewellers can achieve deep, safe, and fast cleaning for gold, silver, platinum, and gemstone jewellery.

What is Sonication?

Sonication is the process of using ultrasonic sound waves to agitate particles in a liquid. These sound waves create microscopic bubbles that collapse rapidly, producing energy strong enough to remove dirt, grease, polishing compounds, and other residues from jewellery surfaces. Unlike manual scrubbing, this process is non-abrasive and safe even for delicate pieces like diamond rings, stone-studded necklaces, or engraved ornaments.

Parts of a Sonicator (Ultrasonic Cleaner)

A sonicator, commonly known as an ultrasonic cleaner, has three main components:

• Generator – Converts electrical power into ultrasonic frequency.
  
  
• Transducer – Converts this electrical energy into mechanical vibrations.
  
  
• Tank / Probe – Holds the cleaning solution where jewellery is immersed.
  
  

At Jewellerytools.in, ultrasonic cleaners are available in different tank capacities such as 2L, 4.5L, 15L, 22L, and 30L, making them suitable for both small jewellery shops and large workshops.

How Does Sonication Work?

When the ultrasonic cleaner is switched on:

• Ultrasonic Waves – The machine generates high-frequency sound waves, usually between 20 kHz to 40 kHz.
  
  
• Cavitation Bubbles – These sound waves create millions of tiny bubbles in the cleaning liquid.
  
  
• Bubble Collapse – The bubbles collapse with force, producing micro-jets that dislodge dirt, oils, and residues.
  
  
• Deep Cleaning – This action reaches the tiniest areas of jewellery such as prongs, clasps, filigree work, and engravings.
  
  

This process is fast, efficient, and eco-friendly, requiring only water or mild cleaning solutions.

Why is Sonication So Effective for Jewellery?

• Non-Damaging: Gentle cleaning without scratching or harming delicate surfaces.
  
  
• Deep Reach: Cleans areas impossible to reach manually.
  
  
• Time-Saving: Cleans multiple items in minutes.
  
  
• Cost-Effective: Reduces the need for harsh chemicals and labor.
  
  
• Versatile: Works for gold, silver, platinum, diamonds, and other precious stones.

How to Use an Ultrasonic Cleaner (Step by Step)

1. Fill the tank with water or a mild cleaning solution.
   
   
2. Place jewellery in the basket inside the tank.
   
   
3. Set the temperature (30°C–80°C depending on model).
   
   
4. Switch on the machine and set the timer (3–10 minutes).
   
   
5. Once done, remove jewellery and rinse with clean water.
   
   
6. Dry with a soft cloth for a sparkling finish.

Frequently Asked Questions (FAQs)

Q1. Can ultrasonic cleaners damage jewellery?
No, ultrasonic cleaners are safe for most jewellery pieces. However, delicate gems like pearls, opals, emeralds, or jewellery with loose stones should not be cleaned in ultrasonic machines.

Q2. How long should I keep jewellery in an ultrasonic cleaner?
On average, 3–10 minutes is enough for effective cleaning. For heavily soiled pieces, the process can be repeated, but avoid over-cleaning delicate jewellery.

Q3. What cleaning solution should I use in ultrasonic cleaners?
Mild liquid soap or a professional ultrasonic cleaning solution works best. Avoid harsh chemicals like bleach or ammonia, as they can damage jewellery.

Q4. Which jewellery is best suited for ultrasonic cleaning?
Gold, silver, platinum, and diamond jewellery respond very well to ultrasonic cleaning. It’s especially effective for intricate designs, engravings, and stone settings.

Q5. Why should jewellers invest in ultrasonic cleaners?
Ultrasonic cleaners save time, reduce manual polishing, and restore a showroom-like shine to jewellery. They are cost-effective and essential for modern jewellery workshops.
