A ceramic hob with two multi-zone radiant heaters. A ceramic radiation heating cooktop has a surface made of low-expansion thermal glass-ceramic that is transparent to infrared. [5] This surface houses radiant or halogen heaters below it. The advantage of this arrangement is that the heat can be quickly controlled.
Built-in and rangetop units typically have multiple elements, the equivalent of multiple burners on a gas-fueled range. Stand-alone induction modules are typically single-or dual-element. All such elements share an electromagnet sealed beneath a heat-resisting glass-ceramic sheet. The pot is placed on the ceramic glass surface and heats its ...
A honing steel on a cutting board Common steel for use in households SEM images of the cross-section of a blade before (dull) and after (sharp) honing with a smooth rod [1]. A honing steel, sometimes referred to as a sharpening steel, whet steel, sharpening stick, sharpening rod, butcher's steel, and chef's steel, is a rod of steel, ceramic or diamond-coated steel used to restore keenness to ...
In a kitchen the hob is a projection, shelf, grate or bench for holding food or utensils at the back or side of a hearth to keep them warm, or an internal chimney-corner. In modern British English usage, the word refers to a cooktop or hotplate , as distinguished from an oven .
Ceramic material is an inorganic, metallic oxide, nitride, or carbide material. Some elements, such as carbon or silicon, may be considered ceramics. Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension. They withstand the chemical erosion that occurs in other materials subjected to acidic or caustic ...
Ceramic knife blades are usually produced through the dry-pressing and firing of powdered zirconia using solid-state sintering. The blades typically score 8.5 on the Mohs scale of mineral hardness, compared to 4.5 for normal steel and 7.5 to 8 for hardened steel [citation needed] and 10 for diamond. The resultant blade has a hard edge that ...
Other ceramic pieces would typically be used as a junction point between the wiring system proper, and the more flexible cloth-clad wiring found in light fixtures or other permanent, hard-wired devices. When a generic power outlet was desired, the wiring could run directly into the junction box through a tube of protective loom and a ceramic ...
Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets using a hobbing machine, a specialized milling machine.The teeth or splines of the gear are progressively cut into the material (such as a flat, cylindrical piece of metal or thermoset plastic) by a series of cuts made by a cutting tool called a hob.
