Heat up Opals in Microwave ! ? (3)
The smell of burnt plastic spread all over when 3 minutes end.
Remove a hot plate by hand towels then to the table.
The colour of Triplet opal has changed quite a bit.
Let's see how the opals are ....
Let's begin with Doublet and Triplet Opal.
Doublet Opal

There wasn't much changes.
Triplet Opal
Left : Before / Right : After
Left : Before / Right : After
Left : Before / Right : After
As you can see here, the difference is obvious ! There's area where it looks like air bubbles on the back side of Triplet opal, which I believe from extreme temperature while heating in the microwave.
The strong, strange smell was actually a burning smell of glued areas, in between a black plastic base and thin layer of opal.
