Bored Panda wanted to gain more insight into the sculptor's work, so we reached out to him with some new interview questions. This time, we were curious about how the artist sources the materials for his pieces. Brian explained: “I've crushed my own scrapyard at this point, after decades of collecting from local machine and auto shops, and people who contact me when they have stuff to unload.”

We also learned more about some of the memorable discoveries the sculptor has made while sourcing materials: “There have been lots of neat finds along the way, like antique silverware and coins, a beautiful clock which I haven't been able to bring myself to dismantle yet.”

When asked about the most challenging objects to work with, Mock shared: “Aluminum is difficult because it’s not as easy to source as steel and it takes a different welder. I've made a few aluminum sculptures for a few outdoor installations, but I prefer not to work with it.”

Lastly, we were curious if Brian ever revisits any of his older pieces to rework them with the skills he has today. The artist said: “All the time! I have grown so much as a sculptor in the 25+ years since I started that I saw pieces from a decade ago that I wish I could ‘fix.’ But on the flip side, I also really appreciate those pieces for what they are, for where I was at the time, and as pieces of my growth as an artist.”
