Frequently asked questions

The non-stick coating is not harmful for health, because the substance of which it is composed (PTFE) is inert, which means that it is not assimilated by the organism. Even if we swallow small pieces of this substance, it would not be dangerous, because they would be eliminated by the body.The PTFE, shortening of polytetrafluorethylene, is a slippery compound, made of “tetra fluoro ethylene” molecules, which are made of carbon and fluorine.

Every overheated piece can provoke emanation of fumes. However, the fume emanated from non-stick pieces does not represent any hazard for users, or pets, except birds. These animals, due to its particularly delicate respiratory system, are very sensitive to any kind of fumes.

One of the characteristics of the non-stick coating is, in fact, the possibility of cooking without using any grease, or reduce it to the minimum, depending on each one’s taste. So, it can be healthier, because the ingestion of fat is significantly reduced. Nevertheless, you must always be careful to not overheat the piece.

The CELAR pieces in tempered glass and in sandstone, with non-stick coating, as well as cake moulds and oven pans, are suitable for using in the oven. All the other pieces, due to their accessories (long handles, side handles, Bakelite and wooden knobs) cannot be used in the oven.

If you use the piece according to the instructions given, you should not have that problem. Though, you have to follow the using instructions.

The qualities of the pieces can be preserved for a long time, if there are adequate maintenance and using. The overheating, the scratches (due to the metallic utensils) and/or cleaning with abrasive products or sponges, are the main causing factors of the wearing out of the coating.

All metallic cookware is conceived to work among certain temperature limits. So, higher temperatures can burn the food, cause stains, and deform the pieces. This overheating can also change the non-stick properties. A moderate temperature is enough to cook, since the aluminium is a good heat conductor. Never leave empty pieces on a turned on heat source, because they can be seriously damaged.

The pieces can be deformed by a thermic shock (for ex.: an overheated empty piece, an heated piece dip in cold water or put on a cold surface, etc.). After using the utensil, let it cool off at air temperature before cleaning it. It is important to refer that a deformed utensil can prevent its use in some heat sources, mainly glass ceramic or induction plates.

No. The non-stick coating is applied during the initial manufacturing process.

You should not use metallic utensils to scrape, because these can damage the coated surface. We suggest the use of plastic or wooden utensils.

No. CELAR products cannot be used in the microwave oven. This type of heating (through the emission of electromagnetic waves) in addition to not being compatible with metal parts it would also damage the coating and its properties in the long run.

All CELAR utensils can be used in gas and electric hobs and in glass ceramic plates. As higher the thickness of the bottom, the better will be the performance in electric hobs and glass ceramic plates.For induction plates, you can only use the CELAR pieces in which are mentioned the symbol “Bymetall” or “F.I.T – Full Indiction Technology”.This symbol means that the pieces have a thermic bottom which allows the aluminium cookware to be used in induction heat source.This new technique consists in the application of a stainless steel special disc on the exterior bottom of the piece, and which gives it the above mentioned capacity, as well as gives more resistance to the piece.
The CELAR utensils can be washed up in the dishwasher machine. However, the water and/or the detergents used may cause some changes in colour brightness of the piece and accessories, without changing, however, its efficiency. To recover the initial view, in non-stick surfaces, you must grease again the interior with a little bit of cooking oil.

To wash up, use hot water, a sponge and liquid detergent. Never use a metal pad or scouring powder.

When the useful life of your Celar’s cookware reaches the end, you should drop it in an Ecocentre or in our facilities at Rua Alto de Mirões, 99, Zona Industrial, 3700-727 Cesar, and therefore contributing for recycling the material.
