❥Please use AB glue to glue the cabochon :-) ❥It’s better not to put the product into oven. If you have to put it into oven, then limit the oven temperature below 45oC(113oF). Please also remember to prevent the temperature changing to quick during oven process, this will also result in defective items. ❥There is a color change coating at the back which may cause the color change. That coating is very important. in order to make the color change better,the coating on the back is not totally flat & would be a bit DOME(rounded edges). We suggest you hollow back bezel for setting. A hollow back will speed up mood color changing function. When you set the cabochon on a hollow back,you’d better seal the back with resin to protect the coating so that it won’t be damaged easily. & we suggest you to add edges on the top of charm/pendant around the mood cabochon to hide the domed part if you don’t want to do a hollow back. ❥ Beads colors varies among 12 different colors by different temperature!
