Glass is placed in the filter funnel to create a fritted glass filter bed. This helps to separate the solid particles from the liquid in the filtration process, allowing the liquid to pass through while retaining the solid material. The fritted glass filter bed provides a uniform porous surface for more efficient filtration.
Though there are exceptions, it is usually an open-top, glass funnel.
It is a glass funnel into which can be placed a circle of folded filter paper (so that it too is the shape of the funnel) liquids may then be poured into the funnel and while the liquids will drain through (to be collected at the base of the funnel), any solids will be retained on the paper.
A filter funnel is typically made out of either glass or plastic, such as polypropylene or polycarbonate. Glass funnels are more durable and resistant to chemicals, while plastic funnels are usually more affordable and lightweight. It's important to choose the appropriate material based on the specific filtering needs and the chemicals being used.
They are used for vacuum filtration to separate crystals, or solids, from a liquid. Usually a neoprene adapter is used to fit the funnel to a flask that is attached to some sort of vacuum. A filter paper is used to make sure no solids get through, or clog, the funnel. Typically, it is advised, that hot solutions are not used in vacuum filtration because the reduced pressure will cause solvents to evaporate, and the solid will precipitate out; causing the funnel, and pores of the filter paper, to clog.
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.

To make pouring liquids easier, and, when filter paper is placed in a funnel, it is used as a filter.

A filter paper is typically held in a funnel during filtration. The funnel is often placed in a ring stand or held by a clamp to support it during the filtration process.
You can use a ring placed on a laboratory stand.

It needs to be flute so it can be perfectly placed in the funnel
Usually, it's used to separate a precipitate from the liquid in the solution. The filter paper is folded into quarters and placed in the funnel. The solution is then poured onto the filter paper, where the liquid filters through and the precipitate stays on the filter paper. The precipitate can then be saved or discarded, depending on which part of the solution you want.
The apparatus required for filtration typically includes a filter paper, a funnel, and a receiving flask or container to collect the filtrate. The filter paper is placed inside the funnel, which is supported above the receiving flask. When the mixture is poured into the funnel, the filter paper allows the liquid to pass through while retaining solid particles. Additional equipment may include a stand or clamp to hold the funnel in place.
