The Swan Collection is the latest product released by RONA in Frankfurt since 2014.
It once again amazed the wine glass industry and
demonstrated RONA's ambition by improving the wine glass to the highest quality!
Q:What is difference between?
A:The potential health risks of lead have led to the development of “lead-free crystal glass”.
This is made by replacing the lead oxide in the production of the glass with barium oxide, zinc oxide, or potassium oxide.
Lead-free crystal is the ideal material for engraving because it is harder and lighter.
Q:Why should we choose lead-free crystal wine glass?
A:(1) Durability: Durable and scratch resistant
(2) Thinness and Delicacy: Enhances the tasting experience by allowing the wine to breathe and releasing its aroma.
(3) Transparency and Clarity: To observe colour and visual appearance of the wine
(4) Compared with the metal sound of the leaded crystal glass, the sound of the lead-free glass is more pleasing to the ears, rich in the reputation of "music" cups.
(5) Lead-free crystal are completely safe
RONA's Pulled Stem process creates a monolithic product from the original two – piece process,
and it significantly enhances its mechanical resistance and thus durability.
RONA nowadays owns automatic technology processes which
simulate handmade production and create products of high quality.
