Hi! If your interested in using plaster Paris as a nozzle, I recommend checking out my channel. It’s all about test firing rocket motors with plaster Paris nozzles and end caps. I have done 1 inch, 2 inch and 3 inch rocket motors using this method. TIP: next time, put in the plaster directly into the metal tube you are using, so there is no risk of it popping out like it did in this video. Im currently finding out solutions for making the plaster Paris stronger,a and a few solutions I found was using glue and ash to create a higher density and less brittle solution. Im currently creating a 4” diameter rocket motor using rocket candy as fuel, a cardboard shipping tube that is 0.15 thick as a insulator, and a Aluminium 6061 T6 tube that fits snuggly into the other tube. The Aluminium tube keeps the motor together from rapid disassembly and holds the psi. I will be making a video on it soon. Good luck!
Maybe try plaster or kitty litter with waterglass/sodium silicate? That should be strong, heat resistant and bind well. Try making some cuts in the inside of the tube to get better adhesion with the nozzle assembly too.
@@GamerPro132 I honestly don't know if they do or not, but it dries as basically glass and is extremely heat resistant. I know that people grind, then pound kitty litter nozzles into rcandy rockets, but I'm not sure if the pressure from your hexamine fuel would be too high for that.
@@chemistryofquestionablequa6252 I see. Well I'm trying to move away from kitty litter for now as I haven't had much luck with it. But maybe I'll go back to it later. I wonder if the waterglass can mix into plaster I'm using without making it crumble.
@@GamerPro132 it should, but you'd have to try to know for sure. It can be made with that crystal cat litter (silica gel) sodium hydroxide and water. It's useful for all sorts of things, from high temperature glue to keeping eggs fresh for a year without refrigeration if you dip them in it.
nice stuff, good luck on the next run

I'm defiantly planning to modify the tube for better adhesion. I'll look into sodium silicate. Do other hobbyists do that?
