有疑問？ 與我們聊天

客戶問題＆回答

  • 題: What is a black scratch stone used for?

    回答: A black scratch stone is primarily used to test precious metals like gold, silver, and platinum. By rubbing the metal against the stone, users can leave a streak that helps identify the metal's purity. This method is ideal for jewelers and goldsmiths who need a quick way to determine the value of their materials.
  • 題: How do I use the Gold Silver Platinum Testing Black Scratch Stone?

    回答: To use the testing stone, first, clean the surface of the stone and the metal piece. Then, make a scratch on the stone with the metal, ensuring a good amount of the metal is applied. Apply a specific testing acid to the streak, and observe the reaction. Based on the color change or reaction, you can determine the metal's purity. This process is essential for those who deal with precious metals regularly.
  • 題: Is the black scratch stone durable?

    回答: Yes, the black scratch stone is made from durable materials designed for repeated use. It can withstand multiple tests, which is perfect for professionals who frequently assess different types of metals. Its longevity ensures that you won’t need frequent replacements, making it a reliable tool for jewelers and appraisers.
  • 題: Can this black scratch stone test all types of metals?

    回答: This scratch stone is specifically formulated for testing precious metals such as gold, silver, and platinum. While it can offer insights into other alloys or metals, its primary effectiveness is in providing accurate readings for these precious metals. This specificity ensures users can trust the results for valuable assessments.
  • 題: What size is the black scratch stone?

    回答: The black scratch stone measures 3 inches by 2 inches and is 1/2 inch thick, making it convenient for both storage and use. Its compact dimensions allow jewelers to easily carry it in a toolkit or workstation. This portability makes it accessible for on-the-go testing, whether at a shop or during field assessments.
  • 題: How often should I clean the black scratch stone?

    回答: It’s advisable to clean the black scratch stone after each use to maintain its accuracy and longevity. Using a soft cloth or brush to remove any residue from previous tests prevents contamination, ensuring that new results are precise. Regular cleaning enhances the reliability of your testing experience.
  • 題: Is the black scratch stone suitable for beginners?

    回答: Absolutely! The black scratch stone is user-friendly and ideal for both beginners and experienced jewelers. Its straightforward testing process allows anyone to understand how to test metals easily. Beginners can also seek additional resources or guidance to better grasp metal testing techniques, making it a perfect starting point in precious metal evaluation.
  • 題: What is the difference between a regular scratch stone and a black scratch stone?

    回答: The difference lies in the material and its suitability for testing. A black scratch stone is specifically designed to highlight the streaks of various precious metals against its dark surface, offering clearer visibility compared to regular scratch stones. This enhanced visual contrast is crucial for accurate assessments, making it a favored choice among professionals.
  • 題: Where can I buy 3" x 2" x 1/2" Gold Silver Platinum Testing Black Scratch Stone for Precious Metals in Hong Kong?

    回答: You can purchase the 3" x 2" x 1/2" Gold Silver Platinum Testing Black Scratch Stone for Precious Metals through Ubuy in Hong Kong. Ubuy offers a seamless shopping experience, allowing you to explore various options and make the best choice for your metal testing needs.
  • 題: Can I use this stone for gemstone testing as well?

    回答: While primarily designed for testing precious metals, the black scratch stone can provide some insights when assessing gemstones as well. However, it is not the most reliable method for determining gemstone authenticity. For more accurate gem testing, dedicated tools should be used alongside the black scratch stone, especially in professional settings.
