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.
The development work was done by a team led by Bill Moreland and Terry Malarkey. The ranges were priced at US$1,500 ($11,050 in 2023 dollars), including a set of high quality cookware made of Quadraply, a new laminate of stainless steel, carbon steel, aluminum and another layer of stainless steel (outside to inside). Production began in 1973 ...

Fracture surface of a fiber-reinforced ceramic composed of SiC fibers and SiC matrix. The fiber pull-out mechanism shown is the key to CMC properties. CMC shaft sleeves. In materials science ceramic matrix composites (CMCs) are a subgroup of composite materials and a subgroup of ceramics. They consist of ceramic fibers embedded in a ceramic matrix.
The conduit methods were known to be of better quality, but cost significantly more than K&T. [2] In 1909, flexible armored cable cost about twice as much as K&T, and conduit cost about three times the price of K&T. [6] Knob and tube wiring persisted since it allowed owners to wire a building for electricity at lower cost.
A Schlenk flask, or Schlenk tube, is a reaction vessel typically used in air-sensitive chemistry, invented by Wilhelm Schlenk. It has a side arm fitted with a PTFE or ground glass stopcock , which allows the vessel to be evacuated or filled with gases (usually inert gases like nitrogen or argon ).
