I would recommend that your readers get a copy of the book, Artisan Bread in Five Minutes a Day by Jeff Hertzberg and Zoe Francois. Many of the breads in the book use a high-quality, half-inch thick baking stone, much like the types used for pizza. Also shown is a pizza peel. The book has many recipes using many types of grains to make peasant loaves, rolls, baguettes, flatbreads and pizzas.
Another suggestion from an outdoor cookbook is to use a large Dutch oven and put small stones or nails in the bottom, then set your baking pan on the stones, and then cover. This way you create a more controlled heat for your baking pan.
As for the pot holder issue, many online kitchen supply stores sell high heat gloves and mitts. I believe Chef Depot has some mitts that will withstand 700 degrees. Also at this time of year it is easy to find high heat gloves in the Barbeque section of most stores. Hope this helps. – Yvonne
