This mirror was made using mastic adhesive and no grout and its all about creating texture. Here's some information to get you started on creating your own mirror:
Mastic is a very sticky / tacky adhesive that is usually used to stick tiles to vertical surfaces.
It is suitable for use for indoor areas only that aren't exposed to moisture.
It's thick consistency allows you to build-up for use with materials of different thicknesses.
When applying it to a surface you want to create a bed for your tesserae to sit in. Be careful, apply the mastic too thin and your tesserae will fall off. Apply too much mastic and your tesserae will be swallowed up in thick mucky goo. You should aim for you adhesive bed to be about 1/3 of the size of your thickest piece of tesserae.
Don't push your tesserae down into the mastic; rather place them gently in the adhesive bed.
Apply mastic with a pallet knife (I used a fid which is a tool used in making stained glass to apply the mastic).
Mastic typically comes in a white powered form that can be tinted with grout colourant. Laticrete make a powered mastic that can be used for indoor applications.
As allows follow manufacturers instructions.
