Reading online today (https://www.getrichslowly.org/early-retirement-extreme/#more-237770) this quote jumped out at me, "It also resists incremental learning because it doesn't make sense or flow until all of the ingredients are known and snap together. (Much like the ERE philosophy!)"
I have been trying to sum up learning the process of glass blowing. It is very much a step by step process but the mastery of craft comes with the flow of each of the steps and being able to adjust when necessary.
We were working recently and discussing the nuances of the glass. Knowing the steps and what to do next is great. It leads to the creation of beautiful things. Knowing why it is what you are doing is key. Learning to put pressure of different levels in different places to shape the glass leads to better design and better results. This is teachable and learn-able but only once a certain level of competence is reached.
Heat is glass is key. Getting enough heat throughout to have the substance move to where you want it to go with ease and efficiency. The hotter the glass gets, the more difficult it is to control. Being on the edge of losing control. Once one becomes comfortable at the control at a certain heat, it is time to get more heat. Once you have the heat that is needed stay in for five more seconds. Learn to master the glass at that next higher level. It is amazing the difference that makes in the process.
