For me it was going into winter. I actually think that it may have had to do with my then 120f honeypot that I proceeded to run even after supersaturation. I am no wizard like these other guys, but in my simple mind, there is less butane to move around a gas bubble, which means the oil is flexing around it, and that creates that notorious violence and bubbling in the wax that ruins glass. I was able to easily switch over to making sauce, crystal type formations, so I quit trying to make shatter. After I corrected that, I have made it, but making shatter out of good material, at least in my opinion, is like having the knowledge, parts, and facilities to make a Lamborghini, but making an 88 Honda instead, but to each their own.
Told that story to tell this story,
…And that according to my best guess based on the troubleshooting we were doing, was our problem. don’t use hot water to take all of the butane out. If you have a pump that is, use that to create the negative pressure (which gives it a relatively lower boiling point WHITHOUT THE INTRODUCTION OF ACTUAL THERMAL ENERGY) on that instead of bulldozing it with thermal energy. Again, I am no wizard, but I am pretty sure that anything that might be in that stew you’re making, has a lower boiling point in degrees as more vacuum is applied. That’s why it happens in the vacuum oven. If you were letting it sit too long in the honey pot and giving it even an extra 5°F, that’s gonna play a huge role as more vacuum is applied. I also went from a $250 Robinair to an Edwards xds. Shit changed, full vacuum was better, And though I think it was the hot water bath’s temp, My vacuum pump is what pushed it over the line. It took me four months And to me a shitload of money to figure it out.
Google H2O boiling point at different vacuum pressure’s. If I remember correctly, I think when your at like 29” and change, water boils and 5 celsius or close to. I’m sure wax, though not the same, is similar in ways to this.
Food for thought.
I hope this helps, and again I am no scientist, if I was wrong in any of the concepts, Let me know so I’m not a dumbass twice.
