THE BENEFITS OF RASTAL HIGH-QUALITY GLASS
Excellent surface brilliance: even after many washing cycles as per DIN 10511, RASTAL HQ goblets and stemmed glasses will retain their brilliant shine.
HIGH-QUALITY CRYSTAL GLASS
Lead-free crystal glass – RASTAL’s exquisite HQ glasses meet the stringent requirements of the Crystal Glass Marking Act (“Kristallglaskennzeichnungsgesetz”).
OUTSTANDING RESISTANCE TO BREAKAGE.
Demonstrated resistance to impact stresses: quality characteristic subjected to standardised pendulum impact testing as per DIN EN 12980.
PERFECT COLOUR NEUTRALITY.
Crystal-clear quality: the clarity of a glass depends on its light transmittance rate. RASTAL HQ glasses exhibit a light transmittance value of 85% or over.
EXCELLENT RESISTANCE TO TEMPERATURE CHANGES.
Great resistance to temperature changes – ideal for catering environments: RASTAL subjects the glasses to regular testing in accordance with DIN EN 7459, whereby the glasses are first heated in a water bath and then quenched in cold water at a temperature of 5°C. These steps are an integral part of our quality inspection process.
A PERFECT BACKDROP FOR CUSTOMISED DECORATION.
The glasses are excellently suitable for bespoke decoration: a huge variety of RASTAL decoration options and techniques are waiting to transform glassware into customised “enjoyware”!
