borosilicate

However, hard glass or borosilicate, would be more resilient.

It was formerly made of low expansion borosilicate glass and ideal for oven use.

Borosilicate originated as laboratory glass, but it has recently become available in color to the studio artist from a number of companies.

Initial results were disappointing due to cracking of the first borosilicate mirror, which was replaced in 1978.

Quartz tubes must be used as borosilicate glass interferes with measurement.

It can serve either function in the form of borosilicate control rods or as boric acid.

Like most laboratory glass, stir rods are made of borosilicate (commonly known as pyrex).

The addition of sulphur to boron-rich borosilicate glasses imparts a blue colour.

The mirrors were constructed by Corning and used honeycombed borosilicate to reduce the weight.

A few picks are constructed of a handblown borosilicate glass that can double as a guitar slide.

Unlike borosilicate, it is not as heat resistant, leading to an increase in breakage from heat stress.

The glass forms include borosilicate glasses and phosphate glasses.

In borosilicate glasses rich in boron, sulfur imparts a blue color.

This is "naturally" low thermal emissivity, found in some formulations of borosilicate or Pyrex.

Sodium borohydride can also be produced by the action of NaH on powdered borosilicate glass.

Such glasses absorb lower frequencies of Infra-red energy relative to conventional borosilicate glasses.

As an example, the coefficients for a common borosilicate crown glass known as BK7 are shown below:

Major types of glass, e.g., borosilicate and soda-lime glass, are not compatible with each other.

Since borosilicate glass melts at a higher temperature than ordinary silicate glass, some new techniques were required for industrial production.

Both of these are used to create electrically conductive paths through the walls of sealed borosilicate glass containers.

Four gross of borosilicate scintillation vials.

The reaction vessel consists of a lipped heavy-wall borosilicate glass tube and a lid made from stainless steel.

Over 800 products are manufactured with Pyrex borosilicate glass including beakers, bottles, flasks, dishes and test tubes.

Most micropipettes are made of borosilicate, aluminosilicate or quartz with many types and sizes of glass tubing being available.
