You can sugar faster if you spray butane on it and let it sit on the oil. What happens is the oil becomes more mobile and the separation can happen faster. Shatter is oiled out thca that was purged too fast to allow it to sugar out. So shatter that sits in heat can basically become more mobile and start to separate the sugars from the terps. Stable shatter means there is about 80%thca and the rest is Terp. Because the thca is so concentrated it will want to sugar out on its own but since the solvent was purged fast to make shatter, this separation didn’t happen. Therefor only heat will speed it up or by adding solvent to it
Here’s something to help visualize those ratios. When we pour out from the machine into jars it’s basically liquid crystal. The jar on the left crashed out too fast and it shows poor formations but it also shows the ratio of thca to terps in the extract. The one on the right is crashing slowly by controlling how fast the solvent leaves the extract and that allows for clean faceted diamonds
