Scraping

In Copper Extension oxidized/waxed items can be scraped to remove oxidation or the wax layer. Like in vanilla Minecraft, the oxidation is removed by using an axe. To do it, you’ll need to put the axe on the off hand, and then your item you want to scrap on the other hand. Then right-click to scrap. And if you want to do all at once, then shift right-click.
