Granite sinks made of SILGRANIT

Our granite sinks consist of Silgranit, a composite material made of up to 80 % quartz sand, the strongest component of granite. This is apparent not only to the eye, but also to the touch. Our Silgranit sinks have a lovely stone-like feel and are extremely easy to clean. What’s more, the material is highly resistant. You want to have free rein in your kitchen, whether you're cooking with tomatoes, strawberries, lemon juice or beetroot. Your sink is impervious to whatever ends up in it, and simply will not allow any discolouration. Only if limescale builds up on the surface of your sink you’ll need to remove it to avoid dirt accumulation. This makes your Silgranit sink an optimal synthesis of functionality and visual appeal

Sometimes, things can really heat up in your kitchen. Silgranit can deal with the usual temperatures reached on pots, pans and baking trays when preparing food. Pots filled with boiling water, baking trays coming directly out of the oven and the like can be placed directly on the sink. Silgranit material is heat-resistant according to DIN standard 13310. The DIN standard is a uniform type of testing especially designed to check whether a product can withstand the usual chores in and around a kitchen sink.

Tip: If you have an overheated pan or tray, we recommend using our top-rails or a heat pad or trivet to protect the surface of your sink and worktop from the effects of extreme heat and differences in temperature.

Silgranit is very easy to clean. For the daily routine, a sponge and a little washing-up liquid are enough. Your sink will shine again. If limescale has settled on your sink, use BLANCO DailyClean+ for cleaning. In our guide, we show you in detail how to clean your granite sink made of Silgranit.

Silgranit consists of 80 % quartz sand, the strongest component of granite. In short: your sink is extremely resistant. As such, you won’t need to worry about putting pots, pans and plates down wherever you fancy in your sink. You can also splash red wine, orange juice, hot coffee or beetroot juice around with abandon. Your Silgranit sink won’t mind one bit.

Yes, Silgranit is resistant to food acids. Acid-based foods like lemons and oranges can be directly prepared on the sink surface. Even vinegar or acid-based cleaning products will not harm the sink surface (i.e. citric acid, acetic acid).

Remember: chloride acids or any other industrial aggressive acids might hurt your Silgranit sink and many other kitchen surface like granite, wood, paint, glass, … so please avoid using them in the kitchen.

No, Silgranit has been developed to come into contact with food and food acids. Hence there is no risk. Food acids won’t harm the sink material. Silgranit has a closed surface that blocks all common household acids. The material remains as it is. Nothing gets in and nothing comes out.

And a Silgranit sink is safe for food, so no sink substances are transferred to food placed on the sink. The food won’t take on any other odour or flavor and can therefore be prepared on the sink safely.

Fresh fruit, vegetables and years of bright sunshine provide the surfaces of your sink with plenty of challenges as time goes on. But they remain completely indifferent. After all, our Silgranit sinks are solid as a rock. The material will not discolour or fade under normal use, and with a little care.

Yes, Silgranit comes with the built-in patented protective formula Hygiene+Plus with antibacterial properties.

SILGRANIT is made with a patented protective formula that makes its surface non-porous and thus water-repellent, dirt-repellent and easy to clean. As a result, Silgranit surface has a shield effect against bacterial growth. This is the Hygiene+Plus protection. The hygienic test* of the material Silgranit has shown that the material inhibits the formation of microbial biofilms and the growth of microorganisms on the material over time.

^{*Tests carried out by DHZ (German Hygiene Certificate GmbH) on behalf of and financed by BLANCO GmbH + Co KG with Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus in April 2022. More details on the tests are available here ( PDF in english / PDF in german ).}

Silgranit is ready to work with a hot mixer tap. Silgranit isn’t fazed by high temperatures, so boiling water won’t be a problem. A hot mixer tap like our TAMPERA delivers water at 100°C directly out of the spout, ready to make tea or cook food. Using it correctly is important to avoid injuries or putting an excessive burden on the sink.

Here our experienced tips:

• Always place a pot or cup below the tap before activating the boiling water and turn it off in good time to avoid spills.

• Be sure to keep your hands away from the running boiling water.

• Remember that the spout might be very hot after running boiling water, so avoid touching it or run some cold water before touching it. This might be very important if you have kids at home.

• Move the spout of the tap to different positions to ensure that the boiling water doesn’t hit always the same spot on the sink or place a cloth on the bottom to avoid subjecting one point of the sink surface to too much boiling water.

Especially on light-colored sinks metal abrasion from pots are quickly noticed. However, these can be easily removed with a soft sponge, water and cooking oil. Moisten the sponge with water, apply the oil and remove metal traces with circular movements. You can find more cleaning and care tips in our guide.

For daily care, rub the sink dry with a microfiber cloth after each use. This will reduce the attack surface for lime deposits.

Silgranite sinks are very durable. Stains do not enter through the closed surface. Sunlight does not affect a granite sink made of silgranite - the colors shine even after years.

Many of the BLANCO granite sinks made of Silgranit are delivered without a hole for the mixer tap - we give you the freedom to decide for yourself where you want to punch the hole for your mixer tap. We have already marked and pre-drilled the places for it on the sink. Have a hammer, punch (tool similar to a metal pin), file, safety gloves and safety goggles ready. Insert the sink into the countertop. Hammer the hole through from the top. To do this, pick the right position, center the punch and tap it with the hammer. Then carefully tap the remaining pieces out of the hole mark with the hammer. In the last step, bring the hole to the right size with the file until it is flush with the pre-milled hole.

Lime can be very stubborn. However, it is easy to remove. Use our professional cleaner BLANCO DailyClean+ and apply it to the stains. Let it work, rinse and wipe dry. In our guide, we show you in detail how to remove limescale stains.

Granite sinks can cope with the usual temperatures reached during the preparation of food in pots, pans and with baking trays. Even filled cooking pots or baking trays coming directly from the oven can be placed directly on the sink. This is proven by the tests according to DIN standard 13310. The DIN standard is a uniform type of test, which is intended in particular to check whether a product can withstand the usual tasks in and around a sink.

Tip: We still recommend placing an overheated pan or baking tray on our TOP rails or a trivet to keep tension caused by extreme heat away from the countertop and sink.
