One area of activity at North Brisbane Lapidary Club that remains popular is lost wax casting. A session is run about every 6 weeks. Members purchase waxes from a variety of sources and then sprue and invest their moulds in individual flasks. Generally the flasks are set over night to burn out and the metal is melted and thrown in the centrifugal caster after about an 8 hour kiln program.
The next work session is scheduled for 27 February so there is plenty of time to get names onto the list – limit of 12 per session. The session is suitable for beginners as instruction will be given and assistance available for new members to help them understand the process.
The photo shows flasks with moulds being prepared for investing ready to sell at the upcoming gem and jewellery festival.
