As a culinary expert with a keen interest in kitchenware, I'm often asked about the suitability of various dishes for different cooking methods. Pyrex, a brand known for its high-quality glass bakeware, has been a staple in many kitchens for decades. When it comes to the question of whether a Pyrex dish can be placed directly on a stovetop, it's important to consider a few key factors.

Firstly, the material of the dish plays a crucial role in determining its heat tolerance. Traditional Pyrex is made from borosilicate glass, which has a high resistance to thermal shock. This means it can handle rapid temperature changes without shattering. However, it's always wise to check the specific product's guidelines, as not all Pyrex products are made the same way.

Secondly, the design of the dish is also important. Some Pyrex products are labeled as "oven safe," while others, particularly those designed for stovetop use, will be labeled as "oven and stovetop safe." It's critical to adhere to these labels, as using a dish on a heat source for which it's not intended can lead to breakage or other issues.

Thirdly, the age of the Pyrex dish can be a factor. Older Pyrex products, especially those produced before the 1980s, are often made from a formula that is more resistant to thermal shock. However, it's worth noting that with age, the glass can become more brittle, and there's a higher risk of breakage when subjected to rapid temperature changes.

Lastly, it's essential to consider the type of stove you're using. Gas stoves tend to have more direct and intense heat, which can be more challenging for some types of glassware. Electric stoves, on the other hand, provide a more even heat distribution, which might be more suitable for Pyrex dishes.

Regarding the reference to vintage Pyrex and Flameware, it's true that older Pyrex products were often used on stovetops without issue, and the Flameware line was specifically designed for direct stovetop use, including for coffee makers. However, it's always best to err on the side of caution, especially with older or vintage items, as their condition and suitability for modern cooking methods may vary.

In conclusion, while Pyrex dishes are generally quite durable and can withstand a variety of cooking methods, it's essential to check the specific product's guidelines and use common sense when deciding whether to place a Pyrex dish on a stovetop. If in doubt, it's better to choose a different cooking vessel designed for direct heat.
