The glass made using this formula had good enough quality that the company could compete in the high-end of the glassware market. [62] This improvement in the formula for glass was considered one of two great advances in American glassmaking during the 19th century, the other being the invention of pressing. [63]
An induction cooktop involves the electrical heating of a cooking vessel by magnetic induction instead of by radiation or thermal conduction from an electrical heating element or from a flame. Because inductive heating directly heats the vessel, very rapid increases in temperature can be achieved and changes in heat settings are fast, similar ...
Induction ranges may be applicable in commercial restaurant kitchens, with lower installation, ventilation and fire suppression equipment costs. [27] Drawbacks for commercial use include possible breakages of the glass cook-top, higher initial cost and the requirement for magnetic cookware.
A cost estimate is the approximation of the cost of a program, project, or operation. The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values. A problem with a cost overrun can be avoided with a credible, reliable, and accurate cost estimate. A cost ...
The term replacement cost or replacement value refers to the amount that an entity would have to pay to replace an asset at the present time, according to its current worth. [1] In the insurance industry, "replacement cost" or "replacement cost value" is one of several methods of determining the value of an insured item. Replacement cost is the ...
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 .
A Allocation of costs is the transfer of costs from one cost item to one or more other cost items. Allowance - a value in an estimate to cover the cost of known but not yet fully defined work. As-sold estimate - the estimate which matches the agreed items and price for the project scope. B Basis of estimate (BOE) - a document which describes the scope basis, pricing basis, methods ...
One example of this is SiC fibres, which can start to degrade via pyrolysis at temperatures above 1470K. [14] One solution to this is to use the glassy form of the ceramic as the sintering feedstock rather than the ceramic, as unlike the ceramic the glass pellets have a softening point and will generally flow at much lower pressures and ...
