That is a easy question. Basically what you need to find out is whether you like silica sand or to use glass changes on a molecular level when heated (chemical change), or is just melted into another form (physical change).
However, after some research, it appears that to make glass, you simply melt silica sand (or some other form of silica) into the resulting product... Glass! There is no chemical reaction or molecular change.
The ConclusionTherefore, making glass from sand is a physical, not a chemical, change.

Is adding sand and water a physical change or a chemical reaction?
It is a physical change, as the nature of the sand remains the same, only its position is changed by wave action.
What evidence do you have that changing sand into glass is a chemical change?
Making glass from sand is a physical because the actual composition of the substance (silica) is not changing. Making glass is just melting all the bits of sand into a large piece (glass).
Is mixing of glass pieces and sand a chemical change or physical change?
