Should have been using straight Alcohol with Phenolic.
With Dextrin i use straight water, and seems like my stars are harder.
I love Sunrise Yellow.

I have only made these stars by pressing and use dextrin and 5 % water then in the dry box and have never had a problem. found a 25 kilo bag of sodium nitrate locally now I don't have make my own. a lot more yellow stars in my future.

I still have a bag of Baking Soda labeled "Lloyd's Favorite" from a couple years ago, so that probably means he hates it.

Cryolite is cheap and nearly insoluble in water. I got a pound of it at a local ceramics supply shop for $4.50. I made some Hardt yellow 3 with it and it was incredibly bright. I didn't have any suitable Al so I substituted 16.2 MgAL for the 19 Al.

I am working on Hardt yellow 3 but it is very hard to ignite. What prime did you use and what mesh size on the MgAl.

I probably used monocapa + bp. I fired them from a small mine which gives easier ignition than in a shell. A dozen stars lit up the whole backyard. My MgAl is -200 +325.
I don't have a copy of the Hardt book but I recently found this:Hardt Yellow Star #5
