Cooking, roasting or baking dishes made of high-temperature resistant Glass

Cooking, roasting or baking dishes made of high-temperature resistant glass are used in households as stove-table dishes, as well Widely used in hotel and diet kitchens. Such harnesses have the disadvantage that because of the bad Thermal conductivity of the glass the food in such cooking vessels with strong, local heating of the cooking utensils Easy to put on or burn »Once the food has been removed, the glass cookware, roasting utensils or baking utensils cannot be used easy to clean, as the food residues adhere firmly to the glass.

It is known, for example, polytetrafluoroethylene coverings by spraying at room temperature and then drying and sintering the order, with a adhesive, heat-resistant covering is created. If you have the inner surfaces of cooking, roasting or baking dishes made of glass with If such a topping made of temperature-resistant plastic is provided, food will stick and burn, even if

Cooking without any fat is definitely avoided. This known polytetrafluoroethylene coating is, however, proportionate slim. It is therefore easy to use cooking, roasting or baking dishes provided with such coverings the risk that this plastic coating when stirred or removed the food or when cleaning the dishes is damaged and thus the advantages of this topping get lost in a short time.

The innovation is based on the object, so as to form cooking ", roasting or baking harnesses of high temperature resistant glass whose inner face is coated with a coating of high temperature resistant plastic, that the coating is not damaged even after a long time of use and maintains its effect.

According to the invention, this is achieved in that the inside of the dishes is completely or partially covered with small, narrow, is provided close to each other bumps. If you look at the inside of such vessels in this way, or at least If the bottom surface is formed with small elevations known from metal frying pans, the service life of the Plastic covering increased considerably. They are useful on the inside of the vessel or on the bottom arranged small, narrow, closely spaced elevations as ribs, Edges or points in square, diamond, rectangular or

Honeycomb shape or arranged in the form of a hammer sole pattern. You can also use the small, narrow dishes, especially in the case of dishes intended for electrical cooking devices Elevations as ribs, edges or points in the form of concentric circles or as a spiral with relatively small Provide a distance from one another.

When using plastic-coated ones designed in this way Cooking, roasting or baking utensils are used when stirring and removing the food The object does not come into contact with the base surface, but only glides over the rib, edge or point-shaped Elevations that protrude, for example, 0.2 to 0.5 mm above the base and a distance from one another of preferably 2 to 10 mm. Should the plastic covering be damaged by using an improper object to stir or Removing the food are damaged, this damage is limited to the highest point of the small, rib-, Edged or pointed elevations «spatula or spoon slide over these bars when stirring and removing the food and can put the plastic coating in the recesses do not touch between the ribs, edges, or tips. Damage can therefore only be on the ribs, edges or Peaks occur. Because these are very narrow and only one

or baking utensils, the utility value of the

rates do not significantly adversely affected and you can use such devices over much longer periods than those _s that are inside only run smoothly with plastic covering. Since the food to be cooked can easily be removed from the plastic coating during cleaning, cleaning the spaces between the individual elevations on the inner surface or bottom side of the vessel does not pose any difficulties.

It is known that cooking, roasting and baking dishes made of glass have a relatively poor heat conduction and that the plastic covering the poor heat conduction from the heating point to the food to be cooked. The plastic covering is made from this Basically kept as thin as possible »According to the innovation, this disadvantage can be avoided by the fact that the Harnesses metallic inlays are available. These can conveniently take the form of metal particles in powder or fiber form the whole body of the cookware, roasting or baking utensils evenly distributed or piled on the bottom of the vessel. By such metallic additives in the glass mass, which are as opposed to touch on both sides, the thermal conductivity can be increased considerably. Depending on the type and purpose of the Cooking, roasting or baking utensils are these metallic additives Evenly distributed over the entire vessel or piled up at the bottom of the vessel

To ensure the heat from the heating surface on every pail Evenly over the entire base of the cookware

to distribute, it can be beneficial in the outer surface of the harness or only in the bottom of the harness a shape corresponding to the bottom and this completely or partially over to embed covering metal mesh or wire mesh in the glass mass.

As a glass mass is in the innovation according to cooking, roasting or Baking dishes have either a white or colored clear or a colored cloudy mass.

The metal powder or metal fiber additives are used during manufacture the modern cooking, roasting or baking utensils added to the glass mass as long as it is in the liquid state. By appropriate choice of the particle size achieves that the metal particles are optimally distributed in the glass and in the liquid for the respective application Float glass mass. When the glass hardens, the glass particles are then completely embedded in the glass mass. Reinforced Deposits on the ground can be achieved by adding metallic particles at the beginning or during the deformation process. The inserts made of metal mesh or wire meshes are pressed in during the forming process, as long as the glass mass is still in a doughy state .

The metallic inserts made of metal powders or metal fibers or metal meshes and nets are expediently

brings that they are completely enclosed by the glass mass. As a result, any adverse effect acting from the outside is excluded on the metal insert excluded «, in addition, when using such cookware», roasting or baking utensils no metallic abrasion occurs.

The increases in the covering surface provided according to the innovation are used in the manufacture of the innovation in the glass material intended. It has proven to be useful to shape the glass with the pattern desired for the covering surface, such as Square, diamond, rectangle, honeycomb or hammer blow patterns to prefabricate and to apply the plastic covering in a constant layer thickness to the prefabricated glass molds,

Cooking, roasting or baking utensils in the design described very often get into the oven. When removing such dishes can only be touched with pot holders. It is therefore provided for the harnesses according to the innovation, these with known removable handle or cloth « Equip handles that snap into corresponding recesses in the body of the crockery.
