Re: Does potassium chlorate have different crystal shapes?
KClO3 has at RT only monoclinic structure. HT is stable above 523 K and has orthorhombic structure. Structure of HP KClO3 is rhombohedral (hexagonal).
RT = room temperature
HT = high temperature
HP = high pressure
RT = room temperature
HT = high temperature
HP = high pressure

Re: Chinese strobe/glitter composition from patents
1. Some of the abstracts in espacenet.com have bad translation. I also check originals. I agree that some compositions do not work properly. For example, red star from CN1598474 burn with white smoke. But corrected work better. 2. CN100999429 and CN103694071 give glitter effect. Close to Winokur one...

Re: New encyclopedic dictionary of pyrotechnics
Thank you Pyro. I found him in facebook. He has unique name.
Redish glitter I saw ones. It was modified Win20 with lithium hyposulfite Li2SO2.
In other cases it was matrix comet (BP base and red strobe microstars).
