Machined Quartz Pieces
The group photo shown at top is an arrangement of machined quartz glass resting on silica sand, which is used to make clear glass. The pure white sand creates a nice effect but some of the individual parts needed to be highlighted to show their details a little better.
The lower photo shows four of the pieces separated from the group, with their details enhanced. The surroundings in three of them have been retouched. The fourth was intended to show some of the machined edges.
