Yes. Using laundry detergent in the boil-out.

Nothing but water in boilout can cause this, also can cause stone sticking issues. Too much excess water in mold can cause spots as well.

wrong program? air leak reducing pressure in flask? poor isolation? outdated material? counterfeit material?

If the bleaching is just around the teeth, its probably do to an incompatible lab putty.

The bleaching located in the intaglio surface . My technician processed the case following correct steps , including flexistone packing flask room temp etc, difference could be detergent was added .. I'm hols now but will try and add photo when home .

Pictures on stuff like this really can narrow down what happened, much better than our guesses.
