The white powder magnesium come to the czech rock approximately 30 year ago. The young climbing audience had invited this new material with exciting. On the other hand the old sand climbers strictly refused to use this.
In czech sandstone climbing areas is magnesium strictly prohibited because of generation mostly old sand climbers. The young boys and womans like magnesium to use and thats why they go to the calc stone and calc rock areas in Frankenjura and Buoux. Whats your opinion about using white powder - is it a sin to use it on sandstones ?
