The various versions of chalk and their benefits

Tips for climbers and boulderers

Solid, granular, dusty or even liquid - many states for the fabric which keeps the hands dry and thus provides a better grip.

The Chalk Block

Block pressed Magnesia is the cheapest variant of Chalk. To keep the Chalk cube shape, a binder is usually added. In addition, it must be crushed before use. That can be a dusty affair. It's best to pack the cube in a cloth and smash it with a hammer. You can then fill in the rough chunks in your chalk bag or in bags.

Powder versus chunks

Loose magnesium carbonate

Chalk in bags is perfect to quickly get a lot of powder on the hands. If your hands are wet, put in a bag full of loose chalk, your hands dry immediately. Quickly shake off the damp clumps and back to the rock. The biggest advantage, however, is also a disadvantage: due to the high dust load, it is forbidden to use loose chalk in many halls. And it invites to waste.

The chalk in bags is usually used outside. But also as a refilling material for chalk balls - later more. The grinded magnesia is available in various grits. But which chalk is best for me? Fine or coarse chalk?

Chunky chalk

Coarse chalk leaves a slightly thicker layer on the skin. Climbers who are slightly more sweating are therefore well advised. The contained lumps can be crushed well and so the chalk can be pressed into the skin.

In addition, the chunks are also used like a chalk stick to mark hidden handles.

Powdered chalk

The powdered magnesium leaves a very thin layer chalk on the skin. This makes the best grip for dry hands - so ideal for little sweating hands. In very fast moisturizing hands, the super-powdery chalk can also become slimy.

Fine powder is also ideal to refill chalk balls, as it better penetrates the pores of the ball and gives enough chalk.

Chalk Balls

The with magnesia filled balls emits powder through a slightly permeable fabric layer. The chalking takes a bit longer for the balls than for loose chalk. Therefore the chalk balls are also suitable for use in the hall. Depending on the fineness of the chalk and the fabric, and how the ball is kneaded, the ball emits a different quatity of chalk. This quantity is usually sufficient for normal hands.

The balls cost something more like loose chalk - however, the balls are often also for refilling.

Liquid Chalk

Liquid Chalk is superfine magnesium carbonate dissolved in alcohol. A few drops before the climbing rubbed on the hands, briefly wait until the alcohol is evaporated, and you have a good base layer magnesium on the skin.

As the chalk is rubbed liquid into the hands, it reaches all the pores of the skin and closes them better. This keeps hands longer dry.

Normally, liquid chalk is not used as a substitute for "normal" chalk, but as an additional tool for difficult or long routes during bouldering and climbing. In combination with the right powder, this can already decide competitions.

Since the liquid chalk leaves a very thin layer of magnesium and still provides good grip, it is also suitable for sports on poles such as power sport or poledance.

Liquid Chalk does not dust and is therefore also in climbing halls and all training rooms, in which the dusty powder is forbidden, a good alternative.
