Materials of BK
Tri-ply is a three-layer construction and consists of an outer layer of 18/0 stainless steel or copper and an inner layer of 18/10 stainless steel, between which a layer of molten aluminium has been applied. The Tri-ply material flows smoothly from the bottom of the pan to the sides and up to the rim. Tri-ply stainless steel or Tri-ply copper ensures quick heating of the pan and ideal heat control. Copper pans are coated with a protective layer. Wash with boiling water before using this product for the first time. Copper pans are not dishwasher safe. The Gastronomic and Conical Deluxe pan series are made from Tri-ply.
In 1960, BK introduced its first stainless steel pans in the shops, under the name BK Karaat. You can still find them in our range, although they have been adapted to meet current quality requirements.
Over the years, quite a few other models - such as Q-linair Master, Q-linair Classic, Conical+, Apple+, Excellent, Profiline, Exclusive, Solid and Conical Deluxe - have been added. BK also uses stainless steel 18/10 for its whistling kettles, BK Kitchen utensils and Lifestyle kitchen utensils.
The material BK uses for its pans and kitchen utensils consists of a steel compound with 18% chromium and 10% nickel. This allows you to cook all possible dishes. Including those with high acidity. Stainless steel is a very durable material that does not rust and is dishwasher safe. The pan bases are made of magnetic 18/0 stainless steel with an aluminium layer between the steel. Aluminium ensures perfect heat distribution and retains heat, which saves energy. The combination of magnetic 18/0 stainless steel and aluminium also makes BK pans suitable for induction.
Traces of use in stainless steel casserole pots
Frequent use of steel kitchen utensils, such as mashers or (stick) mixers, can result in scratches to your pan. Rainbow colouring and white spots are visible. These are caused by a reaction between starchy products, such as potatoes, pasta, etc., and water (lime), heat and stainless steel. These spots can be easily removed with a little cleaning vinegar. There is no need to polish, the vinegar just needs to be swilled around the pan.
Earthenware of red fired clay is used in the Slowcookers. One part of the Slowcookers is untreated, the other part is white-glazed. There are silicone rings on both sides. Look under silicone for more information on this.
Because cooking with the Slowcooker is steam-based and the earthenware absorbs water, the earthenware part of the Slowcooker must first be soaked in cold water for 10 minutes. Earthenware cannot withstand large temperature differences. Always place the Slowcooker in the oven before turning it on. Pre-heating is unnecessary and can actually cause the Slowcooker to burst. The rings serve as a buffer when the Slowcooker comes out of the oven and you should not place the Slowcooker on a colder surface without protection. This is for the same reason, of course, that the Slowcooker may burst.
Silicone - used in the silicone kitchen utensils, the anti-splash lid, the Slowcooker, the Balans spatulas and the Easy Tools - is a type of rubber that is flexible, durable, food-safe and suitable for use in ovens up to 220˚C and microwaves (the silicone spatulas are heat resistant up to 480˚C). But it is also perfectly suitable for the freezer (down to -50˚C). Silicone rubber is a pure material and contains no stabilisers or plasticisers.
Silicone products are produced from 100% silicone suitable for food use, which offers many advantages over traditional metal moulds. Examples of the advantages are that products do not stick, bacterial and fungal growth is prevented and the products are odour and flavour resistant. All products are designed to meet all applicable standards required of (catering) kitchens, cooking schools and bakeries.
Aluminium is usually used for the production of frying pans. This is because an aluminium frying pan gives a very fine and even cooking result. Aluminium pans are lightweight, easy to use, offer good heat distribution and are easy to maintain.
BK applies a durable coating to the outside of its non-stick pans. The Easy pan series has a durable Teflon® non-stick coating on the inside. The Balans+ pans have a heat-resistant Thermolon® coating, which is produced in an environmentally friendly manner. The 2-ply and Tri-ply series of pans, such as the Robust and the Conical Deluxe, also contain aluminium.
Teflon non-stick coating
Thanks to the fantastic non-stick properties of Teflon®Platinum Plus and Teflon®Classic Plus, you can prepare even the most difficult dishes with ease using the Easy Induction, Easy Fry, Easy Basic and Robust 2-ply frying pans, as well as the Easy Cooking pans. You can recognise the genuine Teflon® non-stick coating from DuPont by the different quality labels. These coatings are PFOA-free. PFOA is a harmful component of PTFE, which is used in the manufacture of non-stick coatings.
Ceramic non-stick coating
This non-stick coating is the first non-stick coating based on the revolutionary ceramic nano non-stick technology. This non-stick coating contains no synthetic chemicals, such as PFOA. This new technology is used in the Balans+ pans. The ceramic coating is environmentally friendly and less energy is used in the application of the non-stick coating. Also, less CO2 is emitted during production. During use, no harmful gases are released when frying at higher temperatures.
Pans with this coating are therefore also suitable for temperatures up to 450ºC. This ensures a shorter cooking time, meaning that flavour, vitamins and proteins are better preserved. Fish and meat no longer stick to the pan, meaning that your cooked items can be served neatly.
To enjoy pans with this coating for as long as possible, BK recommends that they be washed by hand using a mild detergent.
