Radu LRC's glass is high-quality, colourful, unique creations that will add brilliance and light to any setting.

These are the steps LRC takes to create a Pâte de Cristal Artwork using the Lost Wax Method:
- create a model from wax
- hand build a kiln mould from plaster/silica around the wax model
- steam the wax out of the kiln mould
- weigh and clean the lead crystal, pack in a terracotta pot
- place the kiln mould in the kiln with the terracotta above
- set the kiln controller to desired firing schedule (minimum 1 week)
- unpack the kiln, discard the terracotta pot (1 use only)
- remove the mould from the glass
- grind the base by hand-lapping with four grades of grit
- soak glass in polish dip for 48 hours
- hand polishing and final stage polishing with pumice and cerium oxide
- engrave signature and number piece on the base


Pâte deCristal technique is rare and ancient. This technique dates back to 5000 B.C. (pieces have been found in pharaohs’ tombs). The process is extremely delicate to master. The pieces produced by the melting of fragments of crystal within a mould have a texture, substance and a softness of contours that can not be obtained with blown glass.

Pâte de cristal is a LRC speciality, sometimes copied but never equalled ; a precious material that gives pieces a sculptural dimension and which has been refined unceasingly. Pâte de cristal has the quality of giving translucency to the forms it reproduces. The brilliance of this material, the intensity of coulours and the myriad subtile shades all contribute to its singularity.

Pâte de cristal is in fact a paste made of crystal with a 45% lead content. Pâte de cristal originates from specially produced batches of crystal melted in crucibles. Several factors have a bearing on the final coulour : the granule size of the crystal fragments, the proportions in the batch, the chemical reaction between some materials and metals, the rate of increase and decrease in temperature within kilns.

The process of melting glass coupled with the lost wax technique that LRC has developed, ensures a perfect reproduction of the original piece just as the artist had imagined it. Pâte de cristal is a mutable substance, which has translated every whim of the imagination of the glassmakers for over a century. Thanks to mastery and constant research, world renowned masterpieces are born

Molding of the model
Starting from sketches, LRC creates an initial model in clay. The volume, details and expressions are worked to perfection. Once the sculpture is finished, it is used to generate a negative mold in elastomer.

Wax pouring
The hot wax is poured into the hollow mold, emptied of the original sculpture.

Reproduction in wax
Once the wax sets, the wax sculpture is removed from its mold.

A perfect reproduction
The wax sculpture can be hiseled and worked to obtain a perfect reproduction, identical to the original.

The wax model is then immersed and encased in heat-resistant plaster. The block of plaster containing the wax model is placed in an oven. Under the action of the heat, the wax melts and runs out of the plaster block through specially-created drain holes. The wax is said to be « lost ».

Filling molds with groisil (coarsely crushed crystal)
Once all the wax run out of the plaster block, the hollow part of the mold thus created is carefully filled with fragments of crystal of different colors and different sizes.


Finishing and polishing process
Once cooled, the plaster mold is carefully broken, to reveal the sculpture in pâte-de-cristal.

There remain a number of finishing operations to be carried out before proceeding with the quality control inspections to ensure the quality of the materials and the distribution of the colors.

Final Piece
You can admire the exceptional color blend and the sculpture details finely hand-crafted. This unique know-how gives birth to exceptional pieces.
