Sintered glass is made from glass powders pressed at a temperature under the melting point of glass.

because sintered glass crucible does not need of prepration and it filter both base as well as acid

Sintered glass crucible is a glass mesh used for filteration. It can be used instead of filter paper, and in fact it is preferrable to filter paper. Sintered glass crucible must be cleaned then dried to constant weig befoe it can be used to filter out precipitates such as silver chloride.

A sinterd funnel is simply a funnel with a built in filter. The filter is sintered, I think that this means that small particles are compressed together (and heated ?) to form a single piece of material with many small holes. The sintered funnels I use are made of glass, a link to some images is below (not mine). http://curlyarrow.blogspot.com/2008/01/how-to-clean-your-sintered-funnel.html I have also used sintered polyethylene and sintered stainless steel for filtering.

sintered iron or bronze

To avoid contamination, especially in chemical analysis.

The crucible is made by mixing graphite with clay.

A small dish made of ceramic material might be a crucible or a Petri dish. The Petri dish is most often made of glass and comes with a lid while a crucible is most often ceramic.

Some examples are: - filtration on a filter paper - filtration on a textile material - filtration on a sintered glass filter - filtration on a sintered metal filter - filtration on bentonite - filtration on active carbon etc.

It is a laboratory object made from glass, platinum or platinum alloys, ceramics, metals (nickel, zirconium), glassy graphite, etc. A crucible is used for the evaporation of liquids from samples, calcination, gravimetric analysis, etc.

Sintered glass is a glass mesh used for filtration. It can be used instead of filter paper, and in fact is preferable to filter paper. Its other advantage is that it is permanent so you can get various different pieces of glassware with sintered glass in it e.g. an enclosed filter suitable for filtration under nitrogen. As for the porosity.... Porosity of sintered glass is labelled by integers from 0-5 (viz. 0, 1, 2, 3, 4, 5) where 0 has a pore size of 160-250 micrometres and is considered course filtration, that is fluid will pass through it quickly and some finer solids will pass through. Whereas, porosity 5 has a pore size of 4-10 micrometers so even ultrafine solids will not pass through and liquids will drop through. I hope this is clear, makes sense and is helpful.

Crucible tongs are huge forceps that are used to hold a hot crucible and remove it from the furnace. Crucible tongs are made from steel that can stand high temperature.

Ceramic magnets are made of a sintered composite of powdered iron oxide and barium/strontium carbonate ceramic.

You answered your own question. Balustrade glass is made of .... glass!

A window. Or what you may refer to is what is glass made of. Glass = Sand.
