Thats a nice deal there! Thank you but unfortunately I won't be able to get that equipment shipped to India. I have to source one from here itself!

Hi! I'm not sure this is the right tread to post but I wanted to share my experience with the direct flame cupellation.

I'm using ordinary household items to perform it: simple propane burner, kitchen measuring spoon and dry portland cement.






a detailed video on the process: https://youtu.be/MwDfUxgNxeA

Hope it will help someone

What type of torch should I use ?. Any Torch with an oxidizing flame.
Any danger of damaging the cupel if using a torch?. You don't even need a cupel. Use some flat clay pot.
Any chance I could lose values if heating too much ?. No, if you stay below 1000 C on the lead.
Anything am I missing ?. Always something is missing.
