The combination of laboratory glassware and non-laboratory parts is interesting. If you'd spoken with someone from a lab, you could have done this whole process without any custom made parts at all. Ring stands, separatory funnels, some buret clamps, etc would have done the trick much more adjustably. Those round bottom flasks on the bottom aren't even round bottom flasks - they are flat bottom flasks. So you could have skipped the lower clamps altogether, and placed these directly on the surface, which would make a much easier to work with system.

Further, how weak the coffee in these images clearly is. Cold brew is typically *stronger* than perked coffee, and the coffee here is watery. It may taste fine; that's your preference.

So what this is ultimately is a poorly considered convoluted contraption with produces extremely weak coffee through a fiddly process.

I love the work you've put into it, and your photos and planning and building skills are clearly great. But the emphasis on form over function doesn't satisfy our need for quality coffee.

If you really wanted to stick with this method, you could use fritted funnels which can be bought much taller than those buchner funnels, and you'd increase the time the water spends with the coffee on it's way down. They would also be clear, which would add to the artsy nature of your project. Harder to clean though. You could introduce some feedback mechanism between the systems so that one would cause the other to drip (probably not hard, but I haven't thought of a way to do it just yet).

Those should probably be stainless fittings instead of brass. Some brass (maybe not your brass) has enough lead to be considered unsafe. (Again, steparatory funnels, which would have teflon stopcocks would avoid this problem altogether.) (Ice could be added from the top too, so you could increase the amount of water in your system without removing parts.)

I do understand that this project isn't about doing things "easier" - it's about "turning something mundane into an exhibition..." But you could have turned the common laboratory glassware into just as much of an exhibition, and the result would be better coffee. And isn't that what we all want?
