What are the names of the processes used to separate sugar from a mixture of sugar and glass pieces?

I would use the processes of dissolving, filtration, and evaporation to separate a mixture that is composed of sugar and glass pieces.


First, the entire mixture can be placed in and stirred in a container of water. The sugar will dissolve in the water, but the glass will not


Next, a piece of filtration paper should be placed in a funnel. The filtration-lined funnel is then placed over a container, such as a beaker. The solution that contains the mixture of sugar and glass is then slowly poured into the lined funnel. The dissolved sugar particles will pass through the filter paper and into the container. Likewise, because the glass pieces are larger, they will be left behind in the filter paper.


The next step will be to separate the sugar from the water. This can be done via evaporation. Because water has a lower boiling point than sugar, it will evaporate first. Thus, the sugar will be left behind in the beaker.
