Home Foundry - Refractory and Insulation Materials for Hobby Metal Casting
High-temperature linings and thermal insulation for DIY crucible furnaces
A home foundry refers to a domestic setup for metal casting, typically used by hobbyists and small-scale artisans, as opposed to large-scale industrial foundries. Whether for casting aluminium, bronze, or other non-ferrous metals, the proper use of refractory and insulation materials is essential for safety, efficiency, and durability.
Hobby furnace construction
Creating a home crucible furnace involves building a chamber capable of withstanding extreme temperatures while maintaining thermal efficiency. Vitcas provides a range of materials specifically suited for DIY furnace construction. For step-by-step guidance, see our blog article on how to make your own foundry.
The inner lining of the furnace can be cast using Refractory Castable rated to 1700°C, ideal for shaping inside a metal drum or bucket. This castable provides excellent thermal resistance and structural integrity under repeated high-heat exposure.
To further protect the interior and enhance temperature resistance, a zircon-based refractory coating can be applied over the cast lining and the inner surface of the metal shell. This coating helps reduce erosion, prevents loose fibres, and increases the overall life span of the furnace lining.
For external insulation, materials such as ceramic fibre blanket or aluminium-coated glass mat can be wrapped around the outside of the furnace. These lightweight insulation products reduce heat loss and improve energy efficiency by keeping the furnace's external temperature lower and safer during operation.
