Macassar Ebony

10/04/19 20:33

Searching for a taste of the exotic? 100 years after Modernism began, more or less, with the founding of the Bauhaus, there’s a conventional palette of materials which we still use. Scotland’s traditional materials like rubble masonry, red deal, slate and harling were supplanted early in the 20th century by beton brut, engineering brickwork, blonde timber and stainless steel. They’re still widely-used, even though none are particularly modern any more.

But Modernism had another strand, exemplified by the Barcelona Pavilion and Aalto’s private house commissions in Finland. Those used a richer palette of leather, darker timbers, bronze and marble. Many of the projects which feature in glossy design magazines today still use this “luxury” palette. No MFI kitchens and laminate flooring for them…

At the moment, I’m working on a range of projects including a centre for people with autism, an aviation academy and a Grade A fit-out for corporate lawyers. As you’d expect, the first one conforms to strict guidelines, the aviation project has an engineering bias, and the lawyers lean towards a sombre palette which is radically different to what the computer games developers in a nearby block wanted.

Macassar Ebony

The lawyers’ office suite looks out over the firth, and the internal doors are finished in a veneer which has parallel stripes of very dark brown to black, alternating with lighter bands of golden brown. At first I thought it might be Zebrano, but having consulted the Architect’s Giant Bedside Book of Exotic Veneers, I think it’s actually Macassar Ebony.

Some use “Macassar” for any Ebony with prominent light and dark streaks, but it’s generally acknowledged as Diospyros celebica. Both Zebrano and Macassar veneers came into fashion a few years ago, but remain in the timber trade’s highest price group. For example, Range Rover use Macassar for dashboard and door cappings, even though their Chief Designer, Colour and Materials, Amy Frascella suggested in an interview I read that there’s a shift in favour of reclaimed and non-leather materials in what she calls post-industrial colours.

That might mean vegan-friendly polymers and fake “pleathers”, plus sustainably-sourced timbers or even post-consumer recycled material. For example, waferboard, strandboard and OSB are different names for the same thing, a board pressed from sawmill waste. Carbonfibre is another possibility, at least in sports cars, and various man-made luxury textiles such as Alcantara.

Natural materials have different advantages, but in all conscience some timbers are difficult to spec, because tropical hardwoods grow very slowly. Teak and Mahogany were popular in the 1950’s and 60’s, but that popularity meant swathes of rainforest were felled and we began to seek alternatives, such as Sapele and Jatoba. Yet timber is only truly sustainable if you plant a tree every time you chop one down – and if you’re prepared to wait for several generations before you harvest that patch again.

Macassar Ebony

As I was hunting for a match for the Macassar wood, I spoke to several veneer suppliers, one of which was located in the East End of London. The cheerful Cockney technical rep decided to have a word in my shell-like, as Arthur Daley would say: “That looks like a laminate rather than a veneer, mate – an expensive high pressure laminate, but it’s a laminate nonetheless.” Cheers, geezer.

It makes sense when you understand the context. Macassar Ebony is rare in veneer form because the trees don’t grow particularly tall, so finding boles large enough to cut door-sized sheets of veneer from is difficult. The small sheet size makes the veneer more suitable for cabinetry, inlay work and making musical instruments. Macassar is also a tropical hardwood, which while not listed in the C.I.T.E.S. Appendices of endangered species, it’s definitely on the I.U.C.N. Red List of vulnerable trees.

The trees are native to the Celebes Islands in the East Indies and they’re named after the Indonesian port of Makassar, which was the main point of export. They’re also found in Maluku and Borneo – although back in the day, many shipments came through India and Sri Lanka. Until the 1970’s, Holt’s Blue Funnel line ships called at the less well-known ports of Sumatra, Java, Borneo and often took on cargoes of exotic hardwoods. Nowadays, due to the trees’ rarity and our concern about the sustainability of tropical hardwoods, Ebony is rightly difficult to get hold of.

Macassar Ebony

It was always thus. Ebony wasn’t readily available in Europe until the 1600’s, although the Greek historian Herodotus records that Ethiopia paid an annual tribute of 200 ebony logs to the Persian Empire. After the 17th century, woodworkers in France perfected the craft of veneering with ebony for furniture and cabinetry and even today, France cabinetmaking is called ebenisterie and a cabinetmaker is known as an ebeniste.

So that explains why Macassar laminate is an acceptable substitute for the real thing. After speaking to the cheerful Cockney, I called up Herodotus on the blower - but he was out of stock, and anyhow doubted whether he could get veneer into the country due to the Brexit Effect. So the moral of this story is that we’re in the market for a convincing laminate, weighing the efforts of Formica, Egger, Resopal and Polyrey.

The best match so far comes from Formica, which captures the colour and tone of a real Macassar Ebony, as well mimicking its texture. Whether or not the lawyers realise it, their choice of door finish is a modern facsimile of an exotic tree which is amongst the aristocracy of timbers. In fact, we covet Macassar wood, and its rarity, so much that we’ve almost logged it into extinction.

I am a Switch

19/01/19 21:05

If you’re searching for a microcosm of Brexit Britain, you could do worse than begin by scrutinising the UK’s widget manufacturers.  Over the past few weeks, I’ve scoured the wholesalers on Dryburgh industrial estate for well-designed electrical widgets, or “wiring accessories” as M&E engineers call them.

As I hunted through trade outlets and online, my path crossed with some Buy British enthusiasts, who are on a mission to support the UK economy at this difficult time; shades of Al Murray’s Pub Landlord and his campaign to Save the Great British Pint… So this is a rumination on whether we make stuff any more, and if so, whether it’s any better than what we import.

Buy British is sometimes overtaken by the imperative to Buy Scottish, but there are a few exceptions.  You’d think that with two of the UK’s Big Six energy suppliers based here – Scottish Power is headquartered in Glasgow and Scottish & Southern Energy in Perth – there would be a thriving electrical components industry in Scotland?  Sadly, no.

Scottish firms concentrate on the heavy end of electrical engineering: Brand Rex at Glenrothes make cables, Belmos in Motherwell make distribution boards, Parsons-Peebles at Rosyth build electric motors, Bonar Long in Dundee used to make power transformers and Mitsubishi Electric at Livingston still makes air conditioning and heat pumps.  However, we appear to have neglected the well-designed, good quality switchplate.

“The door handle,” said Juhani Pallasmaa, “is the handshake of a building.”  Presumably the light switch isn’t far behind.  It’s another point of close contact, yet many switches are made from white moulded plastic, which looks cheap, feels cheap and isn’t made to last.  Neither is there any thought given to its environmental impact – so we should listen to Dieter Rams, the German industrial designer about whom a documentary film was released recently.

Rams was Braun’s chief designer from the late 1950’s to the mid 1990’s, and in that time he designed hundreds of products which we’d now call minimalist.  He wasn’t a stylist, but approached each product ergonomically, so that it would be well made, long lasting and intuitive to use.  

Dieter Rams has been talking about the social, political and environmental impact of design for more than half a century – interestingly, the antithesis of the line taken by late Isi Metzstein, who complained that too much consideration is given to the social and operational aspects of design, as opposed to the architectonic.

Many of the products Rams designed for Braun were made from injection-moulded plastic, which isn’t in the least environmentally-friendly.  However, he and his contemporaries didn’t make disposable goods, they made things to last: lots of people have Braun products such as calculators, radios and kitchen gadgets which still work, 30 or more years after they were made.  30 years or more can’t be said for cheap light switches.  

It’s rarely worth trying to repair white moulded plastic faceplates when they break, and they can’t be recycled either.  Similarly, manufacturing in the Far East then shipping components to Britain is madness, no matter how cheap it is today to stick things in a container.  So, bearing in mind environmental impact as well as aesthetics and practicality, the following thoughts come from my experience as a specifier who insists on seeing and feeling samples, and also from listening to electricians and electrical engineers.

Where to begin?  I’m told that in the 1960’s, Crabtree accessories were robustly made, albeit rather old-fashioned and chunky in appearance.  Then MK Electric produced a slimmer, sleeker style of faceplate which became more popular.  However, sockets and switches from the 1970’s and earlier were made from ivory Bakelite, which is pretty much bulletproof, whereas the moulded urea-formaldehyde plastic used by everyone since then is easy to crack.

Recently, a spark took me aside to ask why architects specify MK Logic Plus so frequently.  He felt it must just be habit, because while MK Logic accessories used to be "Made in UK", MK was bought by Honeywell a few years ago, and some of its products are now "Made in Malaysia".  Their website does say, “MK Electric, unusually for the sector, still manufactures its products for the UK in the UK; with a factory in St Asaph as well as Southend.”  The electrician complained that he often had to return MK accessories to the wholesaler, because the fixing screws were jammed solid against the terminals, and he blamed that on manufacturing in the Far East.  Perhaps that's just prejudice, though.

Which makes would he recommend?  Hager, Contactum, Schneider.  Doing a bit of digging, “In the UK, Hager has a well-established R&D team and global resource to meet the needs of the market. This is backed up by the UK factory.”  Contactum, “is one of a few remaining manufacturers of electrical wiring accessories and circuit protection products in the UK, and manufacturing still continues today at its factory in Cricklewood, London.”  We'll come to Schneider later.

The electrician reckoned that Telco, LAP and Knightsbridge were firms to avoid; according to him they are cheap and appear to be made abroad.  So perhaps there is a correlation between where a thing is made and its quality.  Is that economic nationalism, “common sense” as Al Murray’s Pub Landlord might put it, or pure prejudice?  Many of us are cynical about the quality of imports – in other words, we believe that these things could be made much better than they are.

Personally I used to reach for the MEM catalogue as my default for white accessories – MEM Premera faceplates appeared to be decent quality, looked slim, and a full range of accessories is available.  MEM is now owned by Eaton, an American corporation, which shut down its factory in Oldham in 2005.

But compared to white plastic, metal faceplates win every time.  They’re not manufactured from petrochemicals, they won’t shatter like plastic does, they don’t turn yellow with age, and “live” finishes such as bronze will develop a patina with use, which we find attractive.  Finally, if we’re finished with them the metal can be recycled rather than going to landfill or incineration.

Metal faceplates got a bad rep in the 1980’s when there was an outbreak of Victorian Brass in suburban Britain.  Once that subsided, polished chrome became popular, and now in theory you get a brass, bronze, chrome, stainless steel, nickel or copper finish, as well as powder-coated or clear polycarbonate “invisible” switchplates.  Most of the major accessories firms offer several ranges in metal, and after some research I discovered that quite a few still manufacture them in the UK.

Wandsworth Electrical produce a “premium designer electrical socket which is 100% designed and made in Britain.”  Focus SB sell “Quality Electrical Accessories Made in Britain: we are the only UK company licensed to manufacture electrical accessories for export to China.”  So it isn’t all one-way traffic.  Similarly, Hamilton Litestat have a Union Jack on their website and offer “largely UK-made products”; M. Marcus manufacture all their accessories at a factory in Dudley; and according to G&H Brassware, “All our products are hand assembled at our premises in the West Midlands.”

But the best-designed products I’ve come across were made in Britain by GET Group.  Their sockets and switches were presented in a box with a translucent sleeve which slid back from the carton to reveal a switchplate which followed the same design ethos as the keys on a MacBook’s keyboard.  The plate’s corners were neatly radiused, the rocker edges were rounded off and their action was a well-damped clunk, rather than the nasty click-clack of a £2.50 switch.

GET’s accessories were made from steel and brass and high density polymer, and even came with M3.5 screws in two different lengths, to suit different depths of backbox.  That level of design thinking is rare, especially at the consumer end of the market.  Electricians liked their robustness and the ease with which the terminals could be wired; I guess architects liked their aesthetic, bearing in mind that they were Mac-like, and of course Apple designer Jonathan Ive was heavily influenced by Dieter Rams … so ultimately the widget makers could learn from Rams' design approach and sustainable philosophy.

GET Group plc was swallowed up by Schneider Electric of France a decade ago, and their clever designs have gradually disappeared, which is a great shame.  It’s not clear from Schneider’s website whether they still manufacture in the UK, either.  That adds to the feeling that well-known firms have been taken over by overseas companies, production moved offshore, and the quality may suffer while the brand trades on its past reputation. 

On the other hand, the contract quality fittings which architects specify for higher end projects are quite different to the budget quality you find in B&Q, Homebase et al., and the former are still made in the UK, if not Scotland.  They might incorporate sophisticated electronic dimmers, or bespoke finishes which use metalworking skills developed by locksmiths and ironmongery hardware makers in the Black Country.  

In conclusion, the future seems to lie in making high value products, yet there doesn’t appear to be a design-led electrical accessories firm in this country any more.  Perhaps James Dyson will take up the challenge, having already launched his own ranges of taps and lights …
