Paul mentions that he heats the glass and puts pressure on it by pressing it over the items, but is it actually that simple :) I guess only specific parts of the glass should be heated at least. And should the glass have specific requirements? Thanks for your replies in advance.
This is the answer. Casts the stone, makes a form, slumps the glass.
At least from what he's shown of his works they actually heat glass while its atop the rock.
does that mean he's creating casts of the stones or logs to slump over?
Yes
At least from what he's shown of his works they actually heat glass while its atop the rock.
graphite coating/mold of the shape on which the plate is sunk vertically would be my guess.
That was my exact guess as well... Mold the shape make the tool
At least from what he's shown of his works they actually heat glass while its atop the rock.
This is my best educated guess as to how he makes this, with the spoiler that I think I may be wrong.
My best guess would be he places his base (the stone) in a kiln, and lays sheet glass on top. As the kiln heats up, he can set the temperature so that it starts to slump over top. However, I think I may be wrong because if this were his method the tree trunk would be scorched. Also the glass would evenly melt so it wouldn’t be so flat along the edges.
He could be making molds of the base first to prevent any damage while making the fitted sheet glass.
More likely IMO, he could and be using selective heating to heat the center more than the outside so that he can press down and fit the glass to the base. Much more complex and impressive than it sounds on paper.
Idk how hot kilns are but rocks explode in fire
Around 1700f but also dependent on size.
Rocks are not combustible so they don’t explode, but they can fracture or break apart with thermal energy converted to kinetic energy for sure.
I’d guess it depends on the kind of rock you use, also size to play a factor since I’d imagine it takes a long time for the core of a rock that size to start to heat up at first it would just be surface heat. He could also be making a plaster mold out of the rock then fitting the glass to it later on. Kilns temps can be changed to achieve different desired outcomes, for something like this my best educated guess would be around 1000 degrees Fahrenheit.
The more I observe the work though the more convinced I am he’s using selective heating to fit the sheet glass atop, either that or an extremely elaborate mold process which would take way more time and effort than selective heating.
Rocks with an internal moisture content will absolutely explode due to steam pressure, so be very careful heating rocks unless you really know what you are doing.
You are right but what you are describing is a result of pressure (steam without a provided path for the water vapor to escape) not combustion. I state this explicitly above.
So while there is an “explosion” it’s really just depressurization.
The definition of explosion is: a violent expansion in which energy is transmitted outward as a shock wave.
That would be little consolation after being hit by rock shrapnel. It's an explosion, no need for the quotes. Combustion isn't required.
Smart cookie you are. I think you're right about the selective heating. You clearly know more than I do but I would imagine the rest of the glass starts drooping without any support if it were all in the kiln.
Yeah you’re definitely right about the drooping, unless he’s making some extremely elaborate molds/supports the sides are definitely going to droop. That’s what made me lean away from a kiln melt to selective heating.
Seems simple to heat the middle and place it on top but a lot more complex when you consider how those are huge objects to be moved around and how easy it is to crack the glass is not heated properly throughout
I think if he used your method the stump would have some discoloration from the heat... I sincerely believe this is achieved using molds
You nailed it. He posts videos occasionally of them doing it and its a couple people heating and helping guide the glass so the outside is level and still smooth while the center gets stretched.
What is wrong with my brain, I thought you wanted one of these for your dick
I think he has a video about this on his Instagram
Check out the show “blown away” it’s a really interesting glass blowing competition show. I’ve learned a lot by watching about how diff glass reacts at differing temperatures and how colors are used. Was a fun watch after working in a glass shop/headshop for 5 years
COE ROCK
Ooo I bet the artist is using vacuums.
🏴☠️
Yeah he has videos of how he does it on Instagram. He using a round piece of glass and heats it til it molds to the shape
Cast the object to the desired depth you want it to protrude into the glass, slump it in a kiln. Cold work the edges for the perfect square/circle.
He said in an interview they slowly heat the glass while above the bases until they take form
