Glass gets its color from metal oxides cooked with the pot metal, and from reheatings. Copper oxide anciently gave turquoise blue, green, or red. Cobalt gave light to deep blue. Manganese gave amethyst to purple, and with iron, orange to brown. Iron gave green, and with copper, forest green. Tin gave milk or opaque white. Silver nitrate, reheated, gave yellow. Iron gave brownish yellow. Gold gave amber, or, reheated, gave ruby red; reheated with tin it gave pink, with manganese, purple. Gold leaf, scattered through the bubble, gave aventurine.
When you put a drop of food coloring into a glass of water, the water will turn that color.
Put some in a clear glass jar and see for yourself.
Sand is made into glass by adding several chemicals to help with color and strength of the glass. Then it is put under extremely high heat within a kiln. After it is liquefied, it is shaped.
Put it over some sort of fire so that the glass will melt. You will then shape it into scalptures or even vases to put your flower. There, the glass is now recycled/reused(if that's what you think it is:-P).
Usually you cant, but if the flower is white you can put it in glass with water and pour food coloring in the water. After a few days the flowers will be the color of the water.
You don't. The color is in usually in the glass.
