LAMINAM Cristallo Gold is a fully through-porcelain with water absorption < 0.1 % and needs no sealing. Its care is the simplest of all material classes for worktop surfaces.
Daily cleaning: a soft microfibre cloth, warm water and a neutral all-purpose cleaner or a mild glass cleaner. Afterwards wipe over with clear water and polish dry with a soft cloth — otherwise water marks remain visible, particularly on the light Cristallo Gold surface.
Acid resistance: complete. Unlike marble, lemon juice, vinegar, wine, tomato sauce, coffee, cola or descalers are uncritical on Cristallo Gold and leave no etch marks. In cases of heavier soiling, concentrated specialist porcelain cleaners can be used.
Heat resistance: complete. Hot pans, pots, baking trays or casserole dishes can be set down on the surface straight from the oven — without a trivet. Porcelain is the only material class that offers this carefree heat resistance (engineered quartz and marbles have clear limitations here).
Scratch resistance: very high. Mohs hardness 7–8. Steel knives and usual kitchen tools produce no scratches. A chopping board is not required, but is recommended in order to protect the knives (not the slab), because the hard porcelain blunts the blades more quickly.
UV stability: complete. Direct sunlight outdoors causes no discolouration — Cristallo Gold is equally suited to outdoor kitchens, pool surrounds, terrace tables and south-facing façades.
Stain treatment: all commonly occurring food stains can be removed with warm water and a neutral cleaner. Stubborn stains (dried-on meat juices, turmeric, red wine) can be treated briefly with special porcelain cleaners or a mild paste of baking powder and water and then rinsed off.
Do not use: extremely aggressive acids (hydrofluoric acid HF — relevant to the glass industry, not relevant in households), coarse steel wool, diamond files — these materials could in theory damage the polish, but are not to be expected in a normal household.
Outdoors: regular cleaning of pollen, bird droppings, algae growth and de-icing salt residues — with no special protective measures. Freeze-thaw cycles are uncritical (water absorption < 0.1 %).
Repair: porcelain is very robust, but a direct blow to the edge can cause the material to chip or break — unlike stone, this is difficult to repair. Edge damage generally requires the affected slab element to be replaced or a proper build-up to be applied. Careful fabrication and protective edges are important detail considerations.
