Patinas on a budget

So for the last couple of days I've been talking about living finishes and patinas and how they fit into the world of plumbing fixtures. To review; copper, bronze and brass as reactive metals --they change color and texture as they react to their environment. That change is called a patina. A patina is what corrosion's called when it's desirable. Think about it. The patina silver develops is called tarnish and it's a badge of shame. Copper does the same thing and people call it verdigris and prize it. Interesting.

Now, in addition to those naturally-occurring color and texture changes, the word patina is also used to describe virtually any color applied to metal. Although that word tends to be reserved for colors that mimic a naturally-occurring patina. Make sense?

So, if this is what bronze ingots look like,

And this is true brushed bronze that would end up being used on a $1900 lavatory faucet,

(Plinth, by Paul Martin Wolff)

what are you supposed to do when you have a budget?

Enter our friends at Kohler.

This is a $300 lavatory faucet, the Fairfax single control, and it's being shown here in Kohler's finish, brushed bronze.

Now, when Kohler refers to one of their fixtures as having a brushed bronze finish, they are talking about its color. When Rocky Mountain Hardware talks about brushed bronze, they're talking as much about the composition of the faucet as they are the color of it.

True bronze made by somebody like Rocky Mountain is a labor-intensive process and bronze is a notoriously finicky metal. Not only that, Rocky mountain is a bronze foundry and they make their bronze fixtures and hardware using sand casting and the lost wax method. Surely you remember the lost wax method from grade school social studies. That's right, Rocky Mountain does things the way the ancient Babylonians did and they charge accordingly. I'm not knocking Rocky Mountain for a second here either, seeing the fruits of their labor makes me weak in the knees. It's really beautiful stuff and it's intended to be a once in a lifetime purchase.

But love it though I do, I can't afford to throw thousands of dollars around on lavatory faucets and that's where our friends at Kohler come in again.

Kohler doesn't make that brushed bronze Fairfield single lever lavatory using methods handed down from the ancient Babylonians. But what they do make is beautiful enough.

Large scale plumbing manufacturers cast a faucet from a base metal; usually brass, zinc or a combination of the two. The base metal faucet is polished and then electroplated. Once it's electroplated they then apply a patina and then finally, they seal the color with a clear top coat. As soon as that fixture leaves Kohler's production floor it's locked in time. It will not continue to change. It won't evolve into another color. In fact, it's guaranteed not to change for life.

So if this is Rocky Mountain Hardware's deck-mounted faucet with an applied rust patina,

here's Kohler's answer to that patina, oil-rubbed bronze. Again, what they're describing is the color.

The two faucets pictured up there are separated by production methods, a slight variance in color and about 1500 dollars. The real bronze fixture will continue to change over time and the bronze-colored fixture is guaranteed never to change. Confused? Don't be. Let the price tags be your guide. If a lavatory faucet costs over a thousand dollars, chances are good that it's made from copper, bronze or brass and will have a living finish. If faucet costs under $500, it will not have a living finish and it will look factory fresh for life.

So Monday I'll delve into the exciting world of nickel, chrome and steel. I'm already giddy with anticipation.

No really, what's a living finish?

OK, so yesterday I ran through three basic, reactive metals that come into play when it comes to faucets: copper, bronze and brass. When it's the actual metal we're talking about, manufacturers use terms like "living finish" and "organic finish" to indicate that their fixtures will continue to age and change with time. I'll get into nickel, chrome and stainless (the non-reactives) later, for now I want to stick with copper, brass and bronze.

Now, these living finishes are pretty much the exclusive province of the higher end of the market. For a lot of people, the changeable nature of brass, copper and bronze is a selling point. And that changeable nature comes at a premium.

Here's a $1500 kitchen faucet from Herbeau. It has a living finish of weathered copper and weathered brass.

And here's a $1900 tub faucet in weathered brass, also from Herbeau.

These fixtures are truly made from brass and copper and then they have a patina applied to them in the factory. These patinas are pigments and chemicals that react with the base metal to speed up the aging process. These patinas allow the base metals to look like they're already aged upon arrival. On a living finish, the metal is left unsealed. That is, without a clear top coat to prevent corrosion. Without that clear topcoat, these faucets will also continue to age and their colors will continue to evolve as the base metal reacts with the environment. No two of these faucets will age at the same rate or go through the same color phases. Their continued evolution is completely dependant on the environment where they're placed. Hence the term living finish.

It's important to remember that the world of plumbing fixtures doesn't use the conventions of science to categorize these finishes. Fixture manufacturers across the market use these metallurgical terms to describe a fixture's appearance, and not necessarily its composition. However, when there's a desirable base metal involved, that fact is made amply clear.

Here's a deck-mounted faucet from Rocky Mountain Hardware. It's made from bronze and has had a rust patina applied to it. Rust is iron oxide, a common reddish pigment. So this faucet is made from bronze with a reddish brown patina applied to it. With time it will continue to to turn more brown. It also has a suggested retail price of $1900.

Here's a wall-mounted faucet, also from Rocky Mountain Hardware. This faucet has been cast in bronze and has a medium patina applied to it. It carries a suggested retail price of $1600 and it's mind bendingly beautiful. Bronze has a warmth to it that no other metal comes near. Bronze has been a desirable metal for thousands of years for a very good reason --it's beautiful, strong and lasts forever.

This medium finish also looks suspiciously like something that started showing up in the consumer market around ten years ago, oil-rubbed bronze.

Now oil-rubbed bronze is where my conversation with the Kohler finish developer comes in. Since these living finishes and desirable base metals are the province of the high end of the market, how does this stuff trickle down to the consumer end? Well, come back tomorrow when I tackle the inter-market grudge match between true bronze and  the oil-rubbed bronze gang.

So what the devil's a "living finish" anyway?

I had a similarly phrased question from a reader the other day and it's sent me on a quest to find out. As luck would have it, I'd already set up an interview with a finish developer from Kohler prior to being asked that living finish question, so I asked the source directly and I learned a thing or two.

That Kohler conversation gave me a ton of information to write about by the way, so look for a series on plumbing fixture finishes over the course of the next week or so. But in the meantime, here's a little something I learned about metals and patinas.

This is copper.

This is what happens to copper when it's exposed to the elements. Copper reacts to acids and alkalis in the environment to form a variety of chlorides, sulphides and carbonates known collectively as verdigris. That's French for green gray. Verdigris is composed of  copper carbonate or copper chloride primarily and those chemicals make up the green patina most people associate with copper. 

Copper is a highly reactive metal that's almost never used in its pure form. Generally, copper's combined with another metal to make it stronger and a little less reactive. When copper's combined with tin the result is bronze. These are bronze ingots.

When copper's combined with zinc the result is brass. And here's what raw brass looks like.

Due to their copper content, both metals retain a lot of the reactivity inherent in copper, though it's a bit less pronounced.

So here's what happens when bronze is left to its own devices. It turns a warm brown with yellow tones. These are the doors to the Pantheon in Rome and they're about 1800 years old. They're also the color of dark chocolate.

Brass on the other hand goes golden brown with a slight greenish tone to it.

These naturally occurring patinas are what's meant by a living finish. These patinas take time to develop and really, they never stop developing. After all, they're an ongoing chemical reaction.

When it comes to faucets; copper, bronze and brass are never left in their natural states to be allowed to age into their natural patinas on their own. It can get confusing because most manufactured faucets and fixtures have a patina applied to them. Let's back up for a sec though.

If you remember your basic chemistry, an alloy is the mixture of two or more metals. Alloys like brass and bronze aren't categorized scientifically, and there aren't any standard recipes for these metals. On top of that, copper never shows up in its pure state --it too is usually an alloy that's made mostly of copper. Add to that that the natural process of oxidation is called a patina, but so is virtually any color applied to a base metal. Argh.

I'll dig into this a little further tomorrow, but for now just remember that a living finish is a finish that will age and change color with time. On purpose.

I'm attracted by shiny objects

I've been syncing to a mid-century vibe for the last couple of days and I came across some neat hardware on the site, Satellite.

Satellite is a division of the lighting and hardware purveyor Rejuvenation, and Satellite is where they put their campier offerings that don't quite jibe with the more serious note Rejuvenation's usually aiming to strike.

When you see the whole collection and the layout of the Satellite website, it does strike a more whimsical chord and there are times when that's a welcome thing indeed. Who am I kidding? I love this stuff. I think my favorite thing about doing what I do for a living is that I get to wallow in whatever styles strike me at any given time and I never have to make a decision or live with the results.

I think this is the coolest door knob I've ever seen. 

And if that weren't enough, this door knob coordinates with these Art Deco knobs and pulls.

This cabinet knob reminds me of Sputnik.

And this my friends, is the mailbox I've been waiting for my whole life.

That's just the hardware, get a load of their lighting. Chrome is back kids. Believe it!
