Sure people i know refer to it as “paste stacking” but it originated with crete and he called it “maxx forging”. I’ll dig up a video link in a sec.
Using a gum with stabilisation paste 2 buff on gives you +50 stability if it’s not clear after watching the video, so you can burn some extra gums and push that stability up as long as you want to keep spending pastes. I’ll edit the link on after a forum search.
EDIT: Crete’s Max Forging technique:
I guess “Maxx Forge” was just the name of his shop lol.
Here you can see pics of a forge at round 583, and the first rank 480 item ever posted 
And also some price analysis showing that this would have cost roughly 28k in forging mats at the time.
