Outdoor Bistro Table

My idea is to have the children in each class decorate a tile and then set the tiles on a table iron / metal. Which way should I have children to use? Is the tile must be kilned? Can I go out with acrylic and brightness of protection? Any suggestions would be greatly appreciated. I am a beginner and crafts impaired. Thank you

What a great idea! If you do not want the expense and time are pushed I would not use the oven method. I have an idea, try pre-glazed tiles (Home Depot, Lowes) and use Sharpies to color. They have series with 25-30 different colors and sizes tricks that you could probably find a Michael or office supply store. Good luck!
