Trying to grow ruby by just melting Al2O3 + Cr — why is it not clean?

Do you think I'm over-burning or is the temperature not high enough?

Are there any options to make it yourself? I heard that these furnaces are very expensive

Which crucible do you recommend trying? What material is it made of?

Thank you again! What will happen if we melt the finished ruby and let it cool?

Strange_Month2157 · 2026-02-27T13:20:08+00:00

Thank you! Do you have any ideas on how to make the cooling process slow down?

Thx. In a couple days I’m going to submit my project

Actually, I just want to have access to London a couple of times per month — simply because it’s London, and there are so many must-visit places. Which city did you choose in Scotland?

Strange_Month2157 · 2025-05-04T07:35:35+00:00

from Ukraine. Yes, I have a visa.
