GRS Gemresearch Documentary: Heat treatment of spinel in Mogok, Burma (Myanmar) 2015

Ғылым және технология

In order to understand the potential for colour enhancement of spinels by heat-treatment, we have performed heat-treatment experiments. For this purpose, we have acquired a heat-treatment furnace in Mogok and used the local heat-treatment techniques available in the Mogok area

    Best and most valued gem is untreated. Even slightly different colour. Natural is highly prized. Celebrate all colours of the beautiful gems.

    I have loved the little red spinel octahedrons for a long time, was nice to see one pop out of the gravel it called home!

    No cert. No buying. Thanks for making this known. Many people think that all Spinels are unheated. You have proven it otherwise.

    By the look of the Spinel found at the mine, I would have left it as is. It was a beautiful color without the need for any treatment IMO.

    It's a little tough to make out what the treatment did to the stones as the clip starts with rough crystal then at the end, the guy shows a pre-packed box of faceted and polished gems. You don't actually get a good view of the rough at the end of the process. Can someone clarify? (If I was to guess, I'd say the heat removes the orange-brown hue?) 🤷🏻‍♂Apparently, using vinegar (3:47) is no secret as that comes out in the conversation but the temperature is a secret.

    It has always been said Spinel is not heat treated because treating it would not improve color wipe away inclusions like Sapphire or ruby

    @ali akbar heidari - It is called a *_crucible_* in chemistry, it is made of a special heat resistant ceramic. They are also used in blast furnaces. The ones you can see here are low quality containers : they can only be used once and they break as the man says. A quality crucible is probably too expensive for their use -I am a european biochemist.

    การที่ผู้คนจะหาอัญมณี สักเม็ดนั้นยากแล้ว แต่จะให้ได้ดังใจต้องการ สี ขนาด และ ไร้ตำหนิเลยนั้นยากยิ่งกว่า ผู้คนต่างเสาะหา คนรู้ดูออกก็ไม่ได้มองแค่เป็นหิน กรวด ย่อมรู้ค่าของมัน อัญมณีนั้นก็เหมือนคนนั้นล่ะ คนมองจะเอาให้ดีเลิศ ไร้ตำหนิ อย่างนั้นแบบนี้ บางครั้งคนก็มองไม่เห็น คิดว่าเป็น หิน กรวด คนที่มองรู้ก็ไม่ทันมองเห็น .... นั้นเอง
