That really depends on the baker. For instance, if you’re heavy-handed, glass and stoneware might not be the best choice for you. If you love to make intricately shaped baked goods, silicone may be the way to go. Each material (metal, glass, stoneware, silicone, cast iron) has its own pros and cons. Metal and glass are the most commonly used materials because they have a good reputation for being durable and yielding reliable results, but cast iron and stoneware are great for long-lasting heat distribution and oven-to-table charm.
