Concrete, cast stone and Raysin: differences explained
Why labels matter
Different casting materials can appear equally grey and matte. The marketing term cast stone does not always identify the binder or confirm the intended use. Read the exact product specification.
Concrete
Concrete is fundamentally cement, aggregates and water. Final properties depend on the recipe and surface treatment.
Cast stone
In decorative retail, cast stone may describe several mineral or composite recipes. It does not alone guarantee cement content, waterproofing or food suitability.
Original Raysin 200
Rayher's Raysin 200 is a calcium-sulfate-based casting material mixed with water and allowed to harden. It is not a type of concrete. The manufacturer warns that the material absorbs water and should not remain exposed to moisture.
What does SteinKunstWerk use?
Our own items explicitly identified as Original Raysin 200 are made from that material. Bannik Design describes its products as concrete. Do not interchange the terms. Neither material name certifies a decorative item for direct food contact, water-filled vases, candles or outdoor use.
Cleaning
Follow each item's care advice. Raysin should stay dry; concrete behaviour depends on formulation and finish.
