Capture the form.
Silicone is applied to the original model, capturing the cup and its spinal details. A plaster support holds the flexible mold in shape.

MR.NOPLAN / LOST-WAX CAST GLASS
Spine
Whiskey
Glass.
An exposed backbone. A transparent body. An everyday vessel shaped through wax, plaster and fire.
OBJECT STUDY / LIULIDiscover the making ↓
01 / THE FORM
A backbone.
A different body.
Vertebral forms interrupt the round vessel. Light passes through their edges; the drink brings color to the clear body.
02 / THE MAKING
30 days
from start to finish.
Every cup requires its own wax model, refined by hand and then melted away. Glass takes its place; the plaster mold is broken to release it. Cutting, grinding and detailed hand finishing complete the piece.
A complete making cycle—not just time in the kiln.
02 / Cast + release
One wax model. One cup.
Each cup begins with a new wax model, cast in the reusable silicone mold. Once cooled, it is carefully released. This wax model will be melted away—not used for a second cup.
03 / Refine the wax
The detail begins by hand.
Mold lines, rough edges and small surface imperfections are corrected on the wax model before the next mold is made.
04 / Plaster investment
Enclose the wax form.
Refractory plaster is mixed in the correct proportions, then poured around the refined wax model. Once set, it forms a plaster mold with the wax enclosed inside.
05 / Kiln casting
Placed by hand. Shaped by heat.
The wax is melted out, leaving a cavity. Selected glass pieces are arranged in the cleaned plaster mold, then slowly heated until they soften and flow into its fine contours. A carefully controlled cooling cycle follows.
06 / Break away
Break the mold. Reveal the glass.
After cooling, the plaster mold is broken away. The glass casting emerges with mold material still clinging to its surface.
07 / Clean the casting
Reveal the cast surface.
Water removes the remaining plaster from the castings, exposing the cup’s surface and the spaces between its vertebral forms.
08 / Cut + grind
Remove the excess.
Excess glass is cut away. Grinding refines the casting’s surfaces after it leaves the mold.
09 / Detail finishing
Refine the smallest details.
A handheld rotary tool reaches around the vertebral forms, refining small areas of the glass casting one at a time.
