Diamond State Kaolin Company

We all know that Mill Creek Hundred never had any sort of densely populated area like a city or even a large town. There were numerous small mill towns and crossroad hamlets, places like Milltown, Loveville, Corner Ketch, Milford Crossroads, and Wooddale. There were, however, only three locales that I would elevate even to Village status, each having its heyday at a different point in MCH's history.

First there was the milling and shipping center of Stanton (or Cuckoldstown for you oldtimers), prominent in the late 18th and early 19th Centuries. Then, as it started into decline, the manufacturing village of Marshallton (along with nearby Kiamensi) rose for a time in the mid to late 1800's. Finally, although it had been around in some form since the early 1700's, the northern MCH village of Hockessin became the "place to be" in the later 19th Century. Two of the biggest reasons for this Hockessin Golden Age had to do with the land, namely what was under it and what was built across it -- kaolin clay and the railroad. Recently I ran across a photo of an artifact that sits squarely in the intersection of the two. (Thanks go to Bob Wilhelm for identifying the background of the company involved.)

Kaolin clay (used in the manufacture of bricks and pottery) was first mined just over the border in Chester County in the 1830's, but really got going as an industry in the 1850's. It was at about that time that the first kaolin mine in Hockessin opened, started by Abner Marshall on a property east of the village, between Yorklyn and Sharpless Roads. Marshall initially molded his clay into bricks for sale, but later expanded his operation by opening a pottery. He ran his business for a little more than ten years, when in 1866 he sold it and the properties he had acquired to Charles Parker and John and Thomas Trucks. It is the names of these gentlemen from Trenton, New Jersey that appear on the 1868 map.

Trucks & Parker made only a few changes to the operation when they took over, adding another processing facility but closing the pottery. Although they did still ship out clay, presumably they're listed as they are on the map because fire bricks were the only products they now produced on site. The site, though, proved problematic for the New Jersey firm. According to Joseph Lake in his book Hockessin: A Pictorial History, the property which Trucks & Parker had purchased from Abner Marshall was relatively small, and the kaolin vein was situated under the far western edge of the tract. By 1871 the shaft had become too deep for the mules to pull out the clay-laden carts. The owners were forced to shut down operations for three months in order to install an inclined railway.

With the new railway in place, the mine continued to produce clay productively for another four years. By 1875, however, it was starting to "play out". The clay was becoming more difficult to extract, and some of the buildings were in need of repair. Trucks & Parker decided to sell the property, and it's at this point that we get to A) a little bit of confusion, and B) the point of this whole post.

Lake states that Trucks & Parker was made an offer on the land by Hamilton Graham, a competitor in the local kaolin business. (The entire story of the kaolin industry in and around Hockessin is a full story in and of itself, and one I've only touched a small part of here.) Either Graham didn't actually purchase the property, or he quickly turned around and sold it, because Lake later states that the Trucks & Parker property and facility was bought by.....(and here we are, finally) the Diamond State Kaolin Company.

Diamond State Kaolin paid $300,000 for the interests of Trucks & Parker in 1875, but in retrospect perhaps they should have haggled a bit. As mentioned earlier, one of the reasons it was for sale was that the mine was seen to be nearly exhausted. Some time was obviously spent in working out the deal as the Diamond State Kaolin Company had been incorporated two years earlier, in February 1873. Perhaps they thought there was still more clay to be mined, or maybe they had some other plan in mind. One factor in the decision may have been the recent completion of the Wilmington & Western Railroad, which opened only four months before the incorporation and whose tracks ran directly along the property.

Somehow, Diamond State Kaolin stayed afloat for over a decade, but by the mid-1880's they were in trouble. The company went bankrupt, its land and assets were seized, then they were sold for a fraction of what had been paid the decade before. They were purchased by Golding and Company, which by that time was the preeminent kaolin company in Hockessin, and owners of the land just to the west of the old Marshall/Trucks & Parker/Diamond State property. Golding didn't mine their newest acquisition, but instead repurposed several of the buildings and used the old mine as a dumping area for the tailings pile from their own, larger clay pit. Golding continued to mine kaolin well into the 1930's, but had ceased operations by the time their refinery was destroyed in a spectacular fire in 1943. It's the old Golding pit that is now a lake near the intersection of Old Wilmington Road and Yorklyn Road.

And now, assuming you're still awake after all that background, we'll circle all the way back around to the impetus behind this whole investigation -- the porcelain pitcher at the top of the page. The picture comes from the Delaware Historical Society's website, as the pitcher resides in their collection. It's 8-1/4 inches high, made of porcelain, and has "Diamond State Kaolin" printed on both sides. It was most likely some sort of advertising piece, and my guess is that it's made from kaolin clay mined in Hockessin. There's no date on it, but we know we can date it to roughly 1875-1885. It's a neat little artifact, and a fragile window into one of Hockessin and Mill Creek Hundred's more lucrative eras.

To Belt or Not to Belt?



Part of assimilating into the "lifting culture" means geeking out over new purchases like shoes, wrist wraps, straps, and belts. It's easy to fill up your shopping cart pretty quickly on Amazon.com or other similar websites. The question is, how much of these items are necessary, and what is extraneous and perhaps counter-productive?

I've been hesitant to write this post, because I know many people hold very strong opinions on this issue. There are plenty of people at an elite level who are using lifting belts to deadlift 800+ pounds, so it's natural to want to copy what those guys are doing and hope that all of this gear will lead to similar gains for you. If only that were the case...



Personally, I am not an advocate of belts (and most other "accessories" for that matter, but I'll save that for another post) in many circumstances.

First of all, it's important to understand why you're using a belt in the first place, because I believe a lot people have a great misunderstanding of the purpose of a belt. Some people are under the illusion that the belt will magically prevent back injuries. At the moment, there isn't a lot of evidence to support that belts reduce injury rates or lower back pain in any way. According to the CDC, "although back belts are being bought and sold under the premise that they reduce the risk of back injury, there is insufficient scientific evidence that they actually deliver what is promised."

Stuart McGill also notes that "[individuals] who have never had a previous back injury appear to have no additional protective benefit from wearing a belt," and "those who are injured while wearing a belt seem to risk a more severe injury."

A belt is meant to provide additional support and stability for the muscles of the trunk. Basically, the tension of the belt increases intra-abdominal pressure, activation of the spinal erectors and rectus abdominis. All of these things are clearly important in lifting heavy weight. So why do I have such a conceptual problem with using a belt?

A lifter needs to learn to create intra-abdominal pressure sans belt. When one becomes too reliant on a belt to stabilize his core, the risk of injury without one may increase. Essentially, a belt becomes a crutch for poor bodily awareness and motor learning. If you constantly step under a loaded barbell with your belt on, it's going to be much more difficult to move without it!

A belt will create a false sense of security in a lifter, and thus potentially stunt the growth of postural muscles like the erector spinae, multifidi, external obliques and rectus abdominis, as their roles become more limited with equipment.

In my opinion, a belt is most useful upwards of about 85% of your 1 rep maximum on a squat or a deadlift. That's it. Heavy weights require a greater degree of tension in the body, and that's where the belt will come in handy. You should not be warming up with your belt, and you should not wear it all of the time. When you are working up to a heavy single, or doing a ton of high volume work at high intensity, the use of a belt may be warranted and helpful. If you are not, however, training for a sport that requires you to be stronger than your competitors (such as Strongman, CrossFit, powerlifting or weightlifting), then I don't think using a belt is necessary at all. Instead, you could stand to benefit from a ton of practice in maintaining intra-abdominal pressure without the aid of equipment. Both your intrinsic and external muscles will get stronger in the process.

Again, this is my personal philosophy. Obviously for sports like powerlifting, a belt is going to be necessary after a certain point, but make sure you're strong without it as well. I rarely use belts unless I'm approaching 100% on my lifts. I prefer to train organically, when I can. I feel more accomplished knowing I was able to move a certain amount of weight without the aid of a belt around my waist. Some people like the security of having a belt, but I think it's always better to teach your body how to create that strength on its own.

May Tulips

 This week it is Tulips! 
(And another post with lots of pictures!)

  Even though it doesn't feel like it, they are a little early this year. Around here, tulips usually bloom about Mother's Day.
 I decided to stage these photos on the porch to give you a change of scenery. Their everyday home is on the side table where I photographed the daffodils. They sure look lovely out here too!

 The afternoon sun streams into the porch so gorgeously!
