I was recently asked to make about 20 tiles all 20cm x 10cm for a customer. It really is challenging not only making them- (all the same!) but to fire them too and achieve a consistant -lasting result. Raku by it's nature is pretty randomn, and especially with copper lustre- the effects can be fleeting. I'll try and answer some of these points. Making: Firstly- I made the tiles using roller guides- rolling onto a wooden board, covered with canvass or paper. They key thing is have enough space to work and not to lift or move them! They all need to be a uniform thickness so roller guides area must. Use a template and a ruler- and a potter's knife to cut. A wooden board can be placed on top to stop warping. You will need to periodically check for this as they dry. Make more than you will need. Firing: Supposing you get through the bisque firing unscathed- it's the "fun" part. I place the tiles onto a pad of ceramic fibre onto the kiln shelf. This helps...
