Accidents in the world of food can occasionally lead to the discovery of something delicious, but most of the time cooking mistakes lead to undercooked roasts, spreading cookies and inedible eats.
Even though the cast iron itself is a poor heat conductor, the oil makes the pan effective when it is at a high temperature. The other effect that the seasoning oil has is to make the surface of a cast-iron pan hydrophobic. This makes the pan non-stick during cooking, since the food will combine with the oil and not the pan.
Heating the cookware (such as in a hot oven or on a stovetop) facilitates the oxidation of the iron; the fats and/or oils protect the metal from contact with the air during the reaction, which would otherwise cause rust to form. Some cast iron users advocate heating the cookware slightly before applying the fat or oil to ensure it is completely ...
Spot welding involves three stages; the first of which involves the electrodes being brought to the surface of the metal and applying a slight amount of pressure. The current from the electrodes is then applied briefly after which the current is removed but the electrodes remain in place for the material to cool.

The tip of the electrode needs to be at a lower angle to the workpiece, which allows the weld pool to flow out of the arc. As the electrode melts, the flux covering disintegrates, giving off shielding gases that protect the weld area from oxygen and other atmospheric gases. In addition, the flux provides molten slag which covers the filler as ...
Stashing Costco muffins in the fridge will help keep them fresher longer. Echeverría says the muffins can last seven to 14 days in the fridge. The moist environment might change the texture a bit ...
The connection can be direct, through a narrow tube to reduce mixing, or through a salt bridge, depending on the other electrode and solution. This creates an ionically conductive path to the working electrode of interest. A reference electrode is an electrode that has a stable and well-known electrode potential.
