About Chalk
What is chalk?
Over the years, we have dealt intensively with chalk and would like to share our experiences with you here. There are different types of chalk, different forms and very different additives. You've probably asked yourself what chalk is actually good for, how it works and whether there are any real differences. 🤔
Where does chalk come from exactly?
Chalk usually comes from China. There it is chemically extracted from mined dolomite rock, pressed and dried. The factories there are big, the prices are cheap - in the whole of Europe there is only one source for coarse chalk, and it is relatively new.

Since we also bought chalk there at the beginning, we visited the factories. In the meantime, however, our chalk comes from France, which has various advantages. 🇫🇷
Is Chalk the same as Chalk?
Chalk is magnesium carbonate hydroxide. So far - so good.
However, there are some important differences that are particularly important in climbing. The chalk from China mentioned above is mined and chemically processed - magnesium from the food industry is produced synthetically and is much purer.

At this point you might ask yourself why so much chalk still comes from China. The answer is simple: synthetic chalk hardly holds on the skin because the 'structure' is completely different.

At least so far. 🤫
Chalk from Europe
We looked for it for a long time and talked to many manufacturers. In 2020, the time had come - we were able to switch to chalk from European sources. And that had several advantages. 🥳

Our chalk is now produced under food conditions, so it is much purer and free of heavy metals, for example. You should always keep in mind that chalk is neither food nor cosmetic and therefore does not fall under any regulations.

Another advantage is the special pressing. Our chalk is pressed a little more densely and therefore produces much less dust when you crush the small chunks.
What makes Chalk better?
Chalk has only one job: to dry your hands. Your skin already has the perfect grip - and all you want to do is make full use of it. 🤲

Chalk does not improve the grip, quite the opposite. A thick layer of chalk on your skin will cause you to slip over this layer under stress. You might know this from holds: if the route has been climbed too often, you first have to brush.

Less is more. Much more.
Less is more.
With chalk, it really depends on how thin it is on the skin.

There is always a proportion of bound crystal water in the chalk, sometimes more - sometimes less. However, the more water is bound, the less the magnesium can absorb and the thicker the layer. 💧

Our chalk is particularly pure and therefore 'naturally' thin - but other manufacturers use other tricks.
What else is in the chalk?
You can artificially increase the drying effect of chalk by adding other drying agents. This is usually silicate, which you probably know as a small bag of pellets in packets so that the goods do not become damp.

Since chalk is not subject to any guidelines, as described above, this additive is often not specified.

However, there are also additives that try to improve the grip. This is usually rosin, a resin, or often honey in liquid chalk. These additives are not popular, especially in climbing gyms, because they quickly clog the grips and are extremely difficult to clean. Not to mention that it is questionable to mix honey into liquid chalk. 🍯

We therefore deliberately avoid any kind of additives.
What to look for in chalk
In summary, make sure that your chalk comes from Europe. Make sure that your chalk is free of heavy metals and other additives such as drying agents or resins. And don't forget - the thinner the better.

If you feel that your grip is still not good, here are a few tips to help you. →
What if your grip is just bad?
If, despite everything, you still feel that your grip is not really good, the fault may lie elsewhere.

The best tip is to wash your hands. Remove all dirt and grease from your fingers. Also pay attention to the soap you use. Nourishing soaps often leave a film that worsens your grip. Washing up liquid is best - alternatively, you can use Liquid Chalk at the start of your session. The alcohol cleans your hands and afterwards you can easily switch to loose chalk.

If the chalk doesn't stick to your fingertips, you probably don't have enough skin. There's only one thing that helps: a few days off.
