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 ...
The longer switching cycle time that my induction hobs actually use is likely a hangover from the days of radiant rings and solid plate electric hobs where the thermal mass of the heated metal was much larger, and the thermal time constant consequently much longer and compatible with a several second switching cycle time.
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 .
Repaired ceramic bowl from the National Museum of Vietnam History. A chemical compound that adheres or bonds items together, such as pieces of ceramic. In ceramic conservation there are several different types that range from natural to man-made adhesives. Conservators characterise the best adhesive as one which can be undone.
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 sharpness to ...
Beveled retaining rings feature a 15° beveled or angled edge. This angle allows the ring to wedge itself between the groove and the retained part until it can go no farther, effectively “locking” everything in place. Think of placing a cork in a bottle. The cork is forced into the opening until it is wedged as far into the opening as possible.
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 ...
