Jewellery kilns are an exciting addition to a studio. There are several models available that suit a variety of budgets. Buyers should consider the types of materials they use in their work before selecting a model. Then they can choose a kiln with a ceramic fibre or brick interior that operates digitally or manually.
Choosing the Right Jewellery Kiln for Your Materials
Jewellery makers should consider which materials they intend to fire in the kiln. For example, some machines are perfect for firing Parian ware, but not ceramics. Buyers should choose a kiln that has a higher temperature limit than they require so that their heating elements last longer. They must also consider the size of the materials they use in the kiln and choose a model with sufficient space. Jewellery kilns have either a ceramic fibre or brick interior. Each type of material has advantages and disadvantages.
Jewellery Kiln with a Ceramic Fibre Interior
Ceramic fibre kilns, sometimes referred to as muffles, heat to just over 1,000 degrees Celsius, which means that they cannot fire certain materials, such as porcelain. They have a solid shell with the elements moulded within, which means that these kilns are less likely to experience damage when moved. However, if the element burns out, users must replace the entire interior shell, which can be costly.
Jewellery Kiln with a Brick Interior
Kilns with brick interiors contain fire bricks that can withstand intense heat, which makes them ideal for baking ceramics, including porcelain. Buyers should note that the bricks are heavy and fragile, which means that these kilns are best left in one place. In addition, the heating elements are exposed, so the kiln must always be meticulously clean to prevent foreign matter from causing the elements to burn out. However, exposed elements are easy to replace, if necessary.
Digital vs. Manual Jewellery Kiln
Digital kilns have an electronic processor that controls firing from start to finish, adjusting temperatures as it proceeds. Manual kilns have a knob to control temperatures that is similar to the dial on a standard oven. This means that jewellery makers must adjust the knob during the firing process, in some cases every few minutes, to ensure that the temperature is correct. To help with this process, an external timer or digital temperature controller may be necessary. While manual kilns are often the cheaper option, many users prefer digital kilns for their added convenience.
