BQLZR 3.15x1.57x0.71inch 50ml Rectangle Alumina Aluminum Oxide Ceramic Crucible Boat Shelf Holder 1700 for Tube Muffle Furnaces

The BQLZR Ceramic Crucible Boat has garnered mixed responses from customers, primarily due to discrepancies between product images and the actual design of the item received. Many users expected a crucible with vertical walls, as depicted in the majority of the product pictures. However, they were confronted with a design featuring slanted walls at approximately 30 degrees, which could pose challenges for those hoping to use it for specific applications. While the robust material has demonstrated durability through high-temperature firings, this aspect does not entirely compensate for the disappointment regarding its shape and stability. Prospective customers should be cautious that the base may not sit flat due to an attached piece of material, which can hinder practical use in certain settings or furnaces. Some reviews highlight that it successfully performed well in melting operations, particularly for aluminum, provided users take care to preheat the crucible evenly to avoid cracking under temperature shock. In summary, the BQLZR Ceramic Crucible Boat is a sturdy option for high-temperature applications, but potential buyers should carefully Consider the design discrepancies before making a purchase, as they could significantly affect usability. **
