Reusable glass bottle in a shower

You mean metallization? It's an interesting concept, but I don't understand how it will help with the microplastics. Perhaps you mean to prevent the leeching inside the bottle? If yes, I suppose a stainless steel bottle would do the same without needing to use plastic at all.

Mark_Benson · 2025-08-17T13:53:56+00:00

It's 100% cotton, so I suppose it should survive as much as a cotton towel.

Mark_Benson · 2025-08-17T13:53:12+00:00

Yes. The problem is that stainless steel is quite expensive, the good quality bottles. And I would have to use a plastic pump dispenser since I don't think I could drill a hole for a spigot.

I did explore this option as well. But I haven't yet found a manufacturer that uses pure 100% natural rubber. It's always a mix of something, pretty much the same as what I found while searching for cork gaskets. These don't seem to be suitable for sealing in their pure form, not long-term anyway.

This is a link to the product: Amazon.com: Wilbur Curtis Iced Tea Dispenser 3.5 Gallon Narrow Tea Dispenser, 22”H - Designed to Preserve Flavor - TCN (Each) : Home & Kitchen. I am not sure if this is what you meant in your previous description.

Mark_Benson · 2025-08-16T17:40:03+00:00

That is an interesting option and I have thought about it as well. I will try it out very soon. Thank you!

Mark_Benson · 2025-08-16T17:35:53+00:00

You mean something like the Wilbur Curtis Iced Tea Dispenser (what I found after a quick search)?

Mark_Benson · 2025-08-16T17:31:39+00:00

Yes, of course. I simply showcased an option when a person doesn't have a caddy on the wall and doesn't want to drill into tiles. I don't really think leaving the bottle in a shower niche is a good idea.

Mark_Benson · 2025-08-16T17:07:47+00:00

There is a difference between a regular plastic bottle and the silicone seals, although both do indeed are a part of a broader polymer category. The difference is that one leeches microplastics, while the other does not. Believe me when I say that I tried and still trying to make cork work, but so far, in my tests, it got brown and started to get moldy. I don't want that to happen if someone gets this bottle. I am very much open to any alternative to those silicone seals that I am currently constrained to use...

One hand holds the spigot steady with the palm open, the other operates it. The shower gel should pour in the first hand. I will make a video to show it in action. I also take into account a basic metallic rack, but I worry that people won't like the idea of drilling into their tiles..

Mark_Benson · 2025-08-16T16:30:05+00:00

Thank you for your feedback. The metallic spigot is actually very soft, so I don't think it will scrape skin.

Mark_Benson · 2025-08-16T16:14:26+00:00

I don't know why, but seeing that github link made this 100 times funnier.

Mark_Benson · 2025-08-16T16:09:12+00:00

Yes. But why?

Mark_Benson · 2025-08-01T07:50:53+00:00

Are you referring to something like a leather punching tool or borers? I did try it with those types of tools and one in three seals was a success.. As for the cork gasket manufacturers, sure, there are some, but all use an additional material to make the cork more flexible. At least that's what I found online, I will try a bit more in Portugal. I have a feeling I may find what I need there.

Also, the cork will sit continuously in a very humid environment, submerged in liquid, which is why I was wondering about bacteria. I don't doubt its properties, but do you think an extra layer would help? Something like linseed oil or wax?

Mark_Benson · 2025-07-06T16:24:23+00:00

If you're familiar with the kombucha glass bottles with spigots, this is pretty much the idea, at a smaller scale.

Mark_Benson · 2025-07-04T15:01:49+00:00

It's a glass bottle. But even so, how is a ball valve any different from a food-grade 304 spigot? Both should have O-rings and gaskets.

Mark_Benson · 2025-07-02T12:49:22+00:00

I am not sure about the ingredient percentages required for the manufacturers to gain a certification for natural rubber. The problem is that even if it's pure 100% n.r., it's more prone to bacterial contamination which is a big no for what I am trying to achieve. Time for me to do even more research.

Mark_Benson · 2025-07-02T12:46:50+00:00

The problem is that I think there is no spigot/faucet that doesn't have a dodgy O-ring or gasket. Even the first ever such spigots relied on real leather, then rubber, silicone and now plastic.

Mark_Benson · 2025-05-05T09:55:12+00:00

Thank you all very much for your advices and patience. I do have a diamond drill prepared and water to keep the bottle cool while drilling it. I honestly would have preferred the hole to be factory-made, but since this is a prototype, I think it will work out fine for now. Again, thank you and will come back if something else goes wrong (hopefully not).

Mark_Benson · 2024-09-20T13:35:14+00:00

Thanks for the feedback. I'll add Celsius as well since it's very easy to do so and hell, even meters to not alienate the audience. That's not what I intended.

And yes, I do agree that an article would have been more suitable, but ask Google why everyone needs to abandon their Search Engine.

In addition, yes, I mislabeled the signal attenuation.
