1) Sketch and create templates (make sure students are aware of their base board size so they know how much space they will need to take up)
2) Create a slab, and use template to cut out (I like using x-acto blades, but needle tools work as well)
3) Make 3 extra 6"x6" tiles, these will work as your background tile pieces to break up later
4) bisque fire and glaze fire all tiles (use a kiln safe pencil or underglaze to place initials on back of tile pieces.
6) Start with main tile and then add smaller pieces. You can use a tile nippers for breaking slabs into smaller pieces, but that was kinda fussy for me... instead... we used old canvas to wrap the tiles in before safely smashing them with a hammer. Worked surprisingly well! just remember safety glasses!
7) Glue, glue, glue as you go, one bump from a neighbor could erase a whole days work.
6) Let sit over night after all pieces have been placed down, and grout after 24 hours.
7) If mixing grout, follow box directions, one person told me once that the grout mixture should be the consistency of sturdy browny mix... whatever that means.
8) Once grouted, rub the surface of the mosaic vigorously in circular motions with an old rag, I used old t-shirts. Do this until all tile pieces are clean and grout free. Use a small dab of water on the rag if necessary in spots stubborn to clean.
