The Sonic-Safe Glass Jewelry Washing Cup is a precision tool for organized and chemical-free jewelry restoration.

Borosilicate Glass Construction: Heat-resistant and chemically inert, this high-quality glass ensures no reaction with jewelry cleaners while perfectly transmitting sonic waves from the machine to the jewelry.
Acoustic Transparency: The walls of the jar are calibrated to allow soundwaves to pass through with minimal loss of energy, ensuring your beads and rings receive a full-strength sonic scrub.
Contamination Prevention: Allows for the “tank-in-tank” cleaning method, keeping dirt and debris contained within the jar so your main ultrasonic machine stays pristine.
Portable & Secure: Featuring a wide-mouth design for easy access, this jar doubles as a safe storage container for DIY jewelry projects or bead sorting.
Chemical-Free Refresher: Ideal for those who prefer to use distilled water or eco-friendly solutions, providing a targeted environment for refreshing the luster of delicate stones.

“There is a tactile elegance to using glass that plastic simply cannot match. When you drop your favorite ring or a handful of intricate beads into this jar, it feels like a professional apothecary ritual. You can watch the cleaning process through the clear glass—seeing the tiny particles lift off and settle at the bottom of the cup, away from the rest of your machine. It’s incredibly satisfying for the organized hobbyist; you don’t have to fish through a large tank of murky water to find a tiny earring back or a loose bead. It feels safe, clean, and deliberate. Holding the cool, smooth glass after a cycle, you can see the renewed ‘pop’ of color in your beads and the crispness of your silver, all while knowing your main cleaner is still sparkling clean.”
