How are interstices created in mosaic work?

Interstices in mosaic work are created by leaving small gaps or spaces between the individual pieces of tile or glass that make up the design. These gaps allow for grout to be applied, which helps to hold the pieces in place and create a cohesive finished piece. The size and placement of the interstices can vary depending on the desired aesthetic and style of the mosaic.

Interstices in mosaic work are created by leaving small gaps between the tesserae. These gaps can be filled with grout or mortar, which helps to hold the tesserae in place and create a smooth surface. The width of the interstices can vary depending on the desired effect. Wider interstices can create a more rustic look, while narrower interstices can create a more polished look.
