Captive Exhibition


The Captive (or ‘unfinished’) figures of Michelangelo are the primary inspiration for the series by Brian Richer. Richer, the Creative Director at Castor Design is also a trained stone carver. He has worked on many architecturally significant buildings in North America, and has explored captives for years.

The Captive sculptures are simple Platonic forms, hand-carved with a mallet and chisel – no power tools were used in their carving. Unlike most sculptors—who built a model and then marked up their block of marble to know where to carve—Michelangelo always worked freehand. He saw the sculptor’s job was to reveal the work that already existed within the stone. In these figures one can still see the grooves from the chisel, the process of the work, revealing the hand of the sculptor.

The finished collection is one that presents simple classic forms: a stool, side table, and a bowl emerging from rough blocks of Indiana Limestone partially consumed by the natural material. The result is both recognizable and venerable at once.

Particle Accelerator

​“Nature Abhors a Vacuum”

Despite our growing familiarity with particle accelerators like CERN’s Large Hadron Collider, for most of us the idea of a particle accelerator is still abstract. Castor Design have produced their take on the particle accelerator in an effort to make the science behind the concept more approachable.

The Castor Design particle accelerator is based on research by physicist JJ Thomson at Cambridge in 1897. Thomson is credited with discovering the electron while passing a cathode ray between two electrodes in a glass vacuum tube. Castor’s particle accelerator operates in the same way.

With consideration given to the accelerator’s design, its hand-blown glass tube with machined electrodes is displayed on top of a black marble base with an overhanging shade. Its transformer and vacuum are presented alongside, housed in custom component boxes.

When electrical current is activated and a enough of a vacuum has been formed within the tube in order for electrons to travel without striking a molecule of gas, low­-mass particles accelerate to 30% of the speed of light, which strike other atoms and give off light as they settle.

The arced plasma light quickly stabilizes and “flows” in a straight line across the centre of the tube. As gas molecules undergo more collisions, emission wavelengths appear separated out into plasma bands, demonstrating the Heisenberg Uncertainty Principle. More columns indicate that the electrons’ energy in a given state is less defined. When the vacuum dissipates, the plasma reaches its extinction point and scatters.

Candy Table


Castor Design have made a dining table and a pair of benches out of hard candy. Two inches thick, the treatment resembles a glass-top dining table. The set was made during the 2015 Toronto Design Offsite week for the Dinner by Design charity event hosted by GE Monogram and the Toronto Design Exchange, the proceeds going toward Toronto’s Casey House.

Responding to the theme of the event, at the intersection of dinner and design is an edible table. Following this line of logic, Castor Design made the table top out of hard candy, pouring a 150°C/300°F mixture of sugar, water, syrup, and colouring into a mould on top of an 8’ x 3’ powder-coated steel frame. The hard candy is meant to be used, so after pouring it is left to cool and solidify and then finished with a lacquer spray. Prior to its finishing the table would be edible, having a maple flavour.

The dining set was made at Parts & Labour’s catering kitchen where Castor Design’s principals Brian Richer and Kei Ng are part owners. The table was formed in three separate 60L pours, each with a slightly different shade of red, which results in a marbled texture in the candy. Lit from underneath, the table has molten look that is amplified by the back bench’s slow decline to the floor. Glass tableware is set up to catch the light coming through the table.

The table is installed at the Design Exchange from January 19-25th 2015.

120kg sugar
60kg water
30kg syrup
Food colouring as desired

Bench (x1)
40kg sugar
