That means, on average, the climbing population could be using around 50 million pounds of chalk per year. To be conservative, let's say the average climber uses just two bags of chalk per year. Before switching to liquid chalk, I personally used about three to four 16 ounce (0.6 kilogram) bags of chalk per year. It’s hard to say exactly, but we can make an educated guess.Īs of 2020, there are around 25M rock climbers globally. This can lead to an overall negative impact on both plants and animals that rely heavily upon these environments for survival. The environment suffers from contamination and habitat loss. In areas of heavy dolomite mining, airborne particles settle and cover the landscape. Finally, they’re crushed into chunks or sold as granules. The crystals are then separated out using centrifuges or filters. Next, the ore is ground up into powder form to be added to liquid slurry for drying purposes, but this cools down the slurry too much so it can’t contain as many particles: meaning there will still be some larger pieces that are left in the finished product (the powdered chalk). The extraction process begins by blasting off the rock and removing dust with powerful water jets. Powdered chalk is made of magnesium carbonate, which comes from mining a mineral called dolomite. Let's start at the beginning, how chalk is made and why it matters. However, its environmental impact can be one of the biggest of all our gear. With Earth Day just around the corner, Matt from Pika.life looks at a few of the impacts that climbing chalk has on our environment, and what we can do about them. GUEST ARTICLE - Rock climbing chalk is one of the least expensive and most overlooked pieces of equipment in our climbing gear setup.

Everything about the composition, and the colours – neutral to black with a triangle of sharp cobalt – stands outside time, so that it might be Liège in 1969 or right here and now today. #CUBE WORLD CRAFT WINDOWS#Les images quotidiennes, 24 Sept 69 evokes easels and canvases, windows and curtains, studio light and streetlight, playing with the heavy black outlines you might see later in a Patrick Caulfield. A small painting called Vanité sets up a concatenation of geometric forms in silver-blue and grey that hints at the mirror reflections on a dressing table, as well as the shadows all around it in a bedroom. For it is the back and forth between abstraction and figuration that defines his whole output. In the mid 60s, Wuidar switched to a painting style “free of any realism”, as he put it, “but without denying myself the occasional allusion to the visible world”. ‘Hints of organ pipes, theatre boxes and orchestra stalls’: Un morceau de musique, 1962. Un morceau de musique is the piquant title of this little low-toned song. The earliest painting at the White Cube, from 1962, conflates hints of organ pipes, theatre boxes and orchestra stalls all in one exquisitely condensed sheaf of uprights and horizontals in sepia, chestnut and burnt umber. There are overtones of 1920s Belgian surrealism, of Max Ernst and Magritte. Wuidar works with painstaking care on inexpensive canvases, the weave of which sometimes shows through. Below them, however, is a single dot that turns the whole image into a subtle exclamation mark. The small painting next to it evokes a triangular array of medals, except that the discs are all in ash-greys and browns, as if these posthumous tokens of courage were themselves deceased. But the painting irresistibly reads as a face with a downturned moustache-cum-smile as well, an ambiguity that gives it the air of tragicomic satire. There are hints of architecture – a tiny arcade, the sense of a city square from above – so that the pale triangles seem evocative of searchlights. Victoire, from the following year, is an array of squares and triangles in ethereal greys, dotted here and there with a darker crescent or disc. It only occurred to me, looking closely at the very fine striations of his brushmarks, that the light might be artificial and perhaps even sinister, something closer to the magnesium flash of an explosion. #CUBE WORLD CRAFT SERIES#A project collaboration and documentation platform.A stunning painting called Efflorescence, from 1964, shows what appear to be harvest fields by moonlight: a series of pale grey stems in a radiant gloaming.Membership connects and supports the people and projects that shape our future and supports the learning initiatives for the next generation of makers. #CUBE WORLD CRAFT FREE#
