DIY mosaic tiling? - diy mosaic

I have a small round table with a focus on Formica. I want to try my luck at the forefront of the mosaic. Is it possible, in the Formica, or I have to remove it. If so, what should I use to prepare for "Formica before tiling.

ps I've never tiled. With this framework of a learning project.

Thank you for suggestions, advice.
