High strength Good quality factory mullite kiln shelf for kiln furnace
1. Description
Since the largest mullite kiln shelves commonly available are approximately 2 feet by 2 feet (61cm by 61cm), larger kilns are often outfitted with several kiln shelves, rather than one large shelf. This arrangement works well when fusing smaller items, but the seams between the shelves make it difficult (if not impossible) to successfully and cleanly fuse items that are larger than the individual kiln shelves. As a result, a number of different solutions to the large kiln shelf problem have been attempted. Here's a list of possibilities:
2. Hiding the seams
-
Fiber paper over the shelves
-
Refractory paste to fill in seams
-
Refractory scraps to cover seams (and add texture)
3. Alternative shelf materials
-
Fiber board, vermiculite board, similar products in stock sizes (typically 2 feet by 3 feet/61cm by 91 cm)
-
Custom sizes of fiber board and similar products
-
Rigidized fiber blanket
-
Moldable papers and boards
-
Stainless steel
-
Castable refractories
-
Leveled sand
-
Plaster/diatomeacous earth/vermiculite/alumina mixtures
