LITHOPHANE MATERIAL

[SAVINEL]

Hello,

We are currently working on projects inspired by the lithophany technique. (see attached picture)

These are generally hollow porcelain objects whose surface (interior or exterior) presents bas-reliefs which are revealed when they are illuminated by transparency.
The thinnest parts then appear lighter and the thicker parts darker.

Does anyone have an idea to achieve this effect?

Thank you in advance...
