Flasks, Bases & Gaskets

Flasks, Bases & Gaskets

Casting flasks, bases and gaskets are critical for clean, consistent casting, especially when you're working with silver, gold or copper. These components help maintain a secure, sealed environment during burnout and casting, whether you're using vacuum casting machines or centrifugal units. Suitable for a wide range of jewellery making techniques.

Built to withstand the high temperatures and pressures of metal casting, these parts pair well with crucibles, mandrels and soldering kits. They’re suited for use across all types of jewellery crafting.

Frequently Asked Questions:

1. What size flasks are compatible with my casting machine?

Most machines support standard flask sizes (e.g., 3"x5" or 4"x6"), but always check the machine specs or speak with your casting supplier to confirm fit.

2. How often should I replace casting gaskets?

Replace gaskets when they show signs of wear, loss of flexibility, or reduced seal performance—typically every few months with regular use.
