Worktop horror stories
Having travelled around the world looking for the right partner to make our worktops before eventually deciding the only way to get them made the way we wanted was to do it ourselves, I saw some pretty interesting things, particularly in China and Romania.
The first revelation was just how much difference there is between American White Oak and all of the other oaks, but the real fun started when I was looking at Walnut. For example;
Chinese oak grows in abundance in northern china and southern Siberia, but it is very much the poor relative of the European Oak, let alone North American Oak. A much smaller diameter tree than it’s American counterpart, it has a less attractive grain and many more natural defects; it really is the same in name only.
Forests are not replanted even though they always say they are. The timber is planked, and then instead of being air dried for a few months to let the process begin naturally, it is immediately kiln dried. The only key thing then seems to be achieving low moisture content as fast as possible. This super forced drying creates an unstable plank with internal moisture levels of 20 plus percent, and external levels of less than 4 percent.
The key trick at this point seems to be maximizing the yield of the planks by hiding all of the natural defects, like knots, shake, and not cutting away the sapwood. All they do is turn them over so they are on the reverse side – this means you could well have a knot which is only a millimetre under the top surface of the worktop which is still live, still moving, and could well split right open.
The cooked planks are then taken immediately to the factory, which is mostly on the same site, for manufacture. Some of the factories I have seen are amazing. Rough cut staves being individually cut for finger jointing by hand, then a few daubs of some odd looking glue applied randomly with a brush by some poor and highly disinterested 90 year old, then banged together with a hammer. Then, whilst the finger joints are still wet, without having close sawn the edges to ensure a good fit, the long finger jointed lines are edge glued, again pretty randomly with a brush, before being put in to a giant press to try and stick it all together. Remarkably enough, once the press has squeezed this all together and the worktop has been sanded it doesn’t look so bad. Until, of course, bits literally start coming unglued a few days, weeks or months later. Whilst this is clearly an extreme example, you would be amazed how many of the factories are cutting some of these corners, particularly at the kiln drying and quality control level. Of course this was the extreme - or so I thought...
As for actual finished worktop horror stories, here are a few of what I’ve seen;
Whilst being shown an oak worktop, the factory manager picked up one end and the last three staves in his hand just came away. No one had actually put any glue on them.
I never look at the top worktops in a pile. In one factory, after getting the factory manager to reluctantly take off the top three, the next worktop was a revelation. Some of the staves in the middle appeared to have bits of plastic bag sticking out underneath. When I asked him what this was, he explained it was completely normal to use plastic bags between some of the smaller staves to produce a better fit.
More than a few times I’ve seen Oak worktops which have actually been a mixture of oak and elm.
On more than one occasion, and in fact becoming more prevalent, I’ve been shown oak worktops which were actually ash.
There are a lot of fake walnut worktops around at the moment, which take two forms. The first are ‘Chinese walnut’ worktops. These genuinely are Chinese Walnut, but this is far removed from the beautiful American black walnut which they are being sold as. Much lighter in colour – a bit like a mildly stained oak, they are in fact also much lighter in weight, having only 60 percent of the density of real walnut, which makes them a lot less durable. Some factories do stain them to try and make them look like American black walnut; of course as soon as you cut in to them the truth is revealed. But no matter how well they stain them, nothing can compare to the real thing.
The second type of fake walnut worktop, which really is fake, is far more insidious. A softwood called polyomia has a very light grain structure which, when stained, can look like poor grade American black walnut. The stain is not just applied to the surface, but is in fact pressured right the way through the wood, so even when you cut into it, it still has the same uniform dark appearance. The current trend seems to be to intersperse a few bits of real walnut with the fake walnut, particularly on the front edges, to give a better feel to the worktop. However the fact is 85 % of the worktop is simply a stained softwood which is incredibly soft – I can easily stick a finger nail in a couple of millimetres without even trying. I know of at least two companies selling these in the UK, and I’m pretty certain they have no idea.
To give you an idea why this is done, consider the raw material cost. Top quality rough sawn planks cost the following, per cubic metre;
Oak $ 1400
Walnut $ 2600
Polyomia, I assume top quality, such as it is, is a mere $ 45. Yes, per cubic metre!
So that Walnut worktop which seems so cheap at £ 190 is less than the cost of the raw material alone.
The latest wheeze is European walnut. Much softer than American Black Walnut, Walnut is not even indiginous to Europe - in fact it was first introduced in 1629 by monks. The wood contains significantly higher percentages of sapwood than American Black walnut, and is much paler in comparison, even in the heartwood. Its crushing strength is two thirds that of American Black Walnut. Mostly made in Turkey or Romania as cheaply as possible, it is not recommended. European Walnut will only grow a long way from any other trees rather than in a forest like American Black Walnut. The effect of this is to produce a much smaller, wider tree as it does not have to grow straight up to compete for light with other trees. This is why you never get any long lengths of clear lumber from a European Walnut tree, and hence would never see a single wide stave European Walnut worktop. Lacking four distinct seasons also means the grain structure is wider and thus weaker than American Black Walnut.
Some companies have started to introduce 'African' Walnut. There is no such thing as African Walnut. The tree they are referring to is a coniferous rain forest tree which produces berries which look like walnuts. Illegally logged and on the United Nations watch list as a major cause of rainforest deforestation along with Iroko, it is simply a crime to even consider. We are currently lobbying Parliament to ban the import of these incredibly valuable rainforest hardwoods.
Other horror stories include worktops with staves which are obviously still moving and splitting after being kiln dried far too fast, more worktops with live knots in than I care to remember, but best of all was a factory who’s product contained enough live woodworm to create an epidemic from one worktop alone. Quite normal, according to the factory manager!
Although not a manufacturing horror story, we have noticed more and more websites displaying photographs of infinately superior American Black Walnut worktops when actually selling European Walnut worktops.
