Custom Promotional Glass

Often referred to as the sand clock or the sandglass, the hourglass is a sand timepiece. It, too, necessitates meticulous calibration, just like any other timepiece. When making an hourglass, the person who makes them must do tests and make sure the tool is working properly.

The hourglass's ability to measure time precisely is influenced by a variety of factors. The right sand is essential. It is essential that the flow rate be constant. Custom promotion glass will eventually be worn away by sand that is too fine, resulting in larger neck size. The ratio of the diameter of the sand particles to the width of the neck is the most important factor.

Additionally, the following factors influence an hourglass' precision: How much sand is needed depends on how the custom promotional glass bulbs are positioned. The sand's or granular material's quality. Fine, dry, and consistently formed must be used for smooth flow. Fine-grain sand, powdered eggshells, and powdered marble were all used in the past. The neck's width is an important factor. A tight seal to prevent moisture from entering the chambers should be considered. Sand can become heavier if it is wet, and the neck can become clogged if it is too wet. The hourglass should be placed on a flat, level surface.


The frames, or housings, for custom promotional glass, are open to the designer's whims. Raw materials most often consist of pieces of fine wood that can be crafted or carved to suit a particular style, decor, design, or theme. Bamboo, resin, and various metals like brass, bronze, and pewter are also beautiful framing materials. Specialized hourglasses are made in such small numbers that raw materials are purchased from outside sources for limited issue. Sometimes customers provide their own materials to hourglass makers. Egg-timer hourglasses are also framed in wood or plastic. Manufacturers buy plastic chips from suppliers and make frames in their factories by injecting or extruding them.

Sand is the most complex of the components of hourglasses. Not all types of sand can be used because the grains may be too angular and may not flow properly through the neck of the hourglass. White quartz sand, the sand found on sparkling white beaches, is attractive but not the best for hourglass-making because it is too angular and does not flow smoothly. Marble dust, other rock dust, rock flour (powder from glass cutting) and round sand grains, like those of river sand, are best for sand clocks.

Manufacturing Process

The hourglass's body is blown on a custom promotional glass lathe to the correct size after the design and materials have been chosen.

There may be a single piece or multiple pieces depending on the design of the frame; it may include a bottom and a top, as well as three or four posts. This process is dependent on the materials used. It's possible to make molds, pour the resin into them, wait for it to harden, then sand, or otherwise smooth, polish, or shave the pieces before putting them together. Depending on the materials, the frame pieces can be glued, bonded, or welded together to form a solid structure.

For some reason, many people believe that the amount of sand in an hourglass is determined by some sort of formula. An hourglass shape or design's sand content is not determined by science or a mathematical formula. As the sand flow rate through the custom promotional glass is influenced by a wide range of factors, such as grain type, curvature, and opening size, it is impossible to mathematically predict how many grains will pass through. In order for the sand to flow through the glass, it must be added to the frame and allowed to do so for the prescribed amount of time. The sand on the top of the glass is poured off, and the custom promotional glass is sealed at the end of that time period.
