The thick juice is boiled until crystals are formed, which are a glowing golden yellow color because they are covered with syrup. The syrup is separated from the crystals in a centrifuge. Hot water is used to rinse off any residual syrup. The remaining sugar crystals are clear as glass, and the light refracted from them is white as snow. This sugar is dissolved and re-crystallized to produce refined sugar - sugar that is extremely pure.
