3.13.6 The importance of producing colourless glass The fact that manganese
oxide (potentially a glass decoloriser) occurs at higher levels in the faintlytinted
glasses of type VIII than in colourless glasses of types 111 and V, with iron
impurity ...

Decolorisers. Manganese dioxide (pyrolusite) was the decoloriser used by
Venetian glassmakers to neutralise the colour due to Fe impurities in the raw
materials. Its use is first mentioned in a document of 1290. It was imported from
Piemonte ...

Quality Assurance of Aseptic Preparation Services
Holding the slide with the forceps, apply alcohol/acetone decolorising solution to
the wet slide. This stage is critical and the decoloriser should only be left on for 5-
10 seconds. Rinse again with running water and place the slide on the rack.

Biopharmaceutics & Pharmacokinetics
But both the properties are not an absolute as it is based on the rate at which the
cell release the complex to decoloriser. Various other factors such as freshness
of stains used, cell density of a smear, nature and concentration of decoloriser ...
For example, no more than \ (one half) part by weight of arsenic per 1000 (one
thousand) parts of sand is all that is required to act as a decoloriser, and
stabiliser to selenium ; any larger amounts make it necessary to use larger
quantities of ...

The batch composition was progressively simplified until it was composed of
sand, limestone, and soda ash with a very small addition of saltcake and of the
decoloriser, which was made up from arsenic, selenium, and cobalt oxide (see

In order to produce good colourless glass, a mechanical mixer is essential as the
amounts of decoloriser required are so small that bad mixing will result inevitably
in patchy colour. In adding the decoloriser, it has been found that quite as good ...

decolorising follow at about the turn of the century, though there was at the time
some uncertainty about its efficacy. Cousen & Turner'191' referred to selenium as
a 'secondary' decoloriser, i.e. following the oxidising action of arsenic.
