Lost wax casting powder is offered for copper-jewelry DIY and workshop requests. The powder/water mixing reference is 100 g powder to 38–40 mL water. Choose the actual gold, silver or copper selection label and confirm its color/formulation or intended-alloy role for the jewelry process.
Working interval and initial setting
Working time is 8–10 minutes, while initial setting time is 10–12 minutes. Agree the selected formulation's preparation and measurement conditions for those separate intervals. Define the actual mixing and investment procedure against the jewelry pattern and accepted working sequence.
Maximum burnout and expansion limit
Maximum burnout temperature is 750°C (1382°F), with expansion no more than 0.08%. Confirm the selected powder's actual test and operating conditions. Obtain the complete burnout instructions for the investment process, keeping the maximum-temperature reference separate from the required schedule and any molten-metal temperature.
Fluidity and smooth-surface acceptance
Fluidity directions are 15–18 cm and more than 18 cm. Confirm which result applies to the chosen formulation and how it is measured. Smooth surface and minimal/no-bubble conditions are acceptance directions to agree under the actual preparation process. Define the accepted surface and bubble level for the particular jewelry job.
Option role and offered support
Match the selected powder option to the actual alloy and investment requirements after its designation is clarified. Online technical support and onsite inspection are offered. A one-year warranty is available, with its actual powder/service coverage to agree. Confirm the formulation, operating instructions and required acceptance with that support scope before choosing the powder.
