Of course you can. If you want to crystallize silicate and study degree of crystallization and texture evolution for example, start with a melt with the right composition and cool down at different velocities. you will obtain different amount of crystals with different sizes.
Sure, you can. Mix reagent-grade oxides (and carbonates) in the right proportions for your target silicate glass composition. Grind these powders together, and then melt them into a homogeneous glass at a temperature higher than the liquidus temperature. You can carry out crystallization experiments using different high-temperature experimental techniques. There is a vast literature on this topic. When you cool the glass from high-temperature, crystals with various composition will grow: their size, shape, proportions will depend on the cooling rate, the cooling path, starting glass composition, temperature, pressure, oxygen fugacity ..... Good luck!
Yes. You may kindly refer an article on "Crystallization and Densification of Nano-Size Amorphous Cordierite-Powder Prepared by a PVA Solution–Polymerization Route

[1]All the silicates are molten at about 1200°C and all are solid when cooled to about 600°C. Often the silicates are grouped as high, medium and low-melting point solids.
[2] The principle formation of crystals of silicates is ANALOGOUS TO FRACTIONAL CRYSTALLIZATION SO THAT SILICATES WITH HIGH M.PTS. CRYSTALLIZE FIRST AND THOSE WITH LOW M.PTS. CRYSTALLIZE LAST.
[3] MAGMA is the term used to describe their molten material . There is a considerable range of melting temperatures for different compositions of magma.
[4]Upon cooling from the completely molten state, it is typical for SILICON TETRAHEDRA TO FORM FIRST AND THEY, IN TURN, JOIN WITH EACH OTHER AND THEN WITH OTHER IONS TO FORM NUCLEI FOR CRYSTAL GROWTH.
[5]The crystal growth may continue unhindered as long as the surrounding material remains molten.
[6]Depending upon the surroundings and the rate of cooling, the
crystallization is complete; no matters the time differs and the result is a solid mass of interlocking crystals of different sizes.
[7] When the silicate with highest mpt has crystallized, then comes the turn of silicate with mpt having value immediately less than the first one and so on
to obtains a number of fractions each containing a specific silicate with different sizes , colors( may) and shapes.
