Cork
Cork is the bark of a cork oak tree, commonly found across Portugal. It takes years for a mature cork tree to produce quality cork to harvest by skilled trades to not damage the tree. Cork is mainly known for wine stoppers but it has so much more potential. It's light weight but surprisingly heavy when in a block form. It naturally repeals water and is antimicrobial, meaning it suppresses the growth of mirco-organisms such as mould or bacteria. It is also flame retardant so there is no need for chemicals when using cork. From fabric, blocks, granules to wine stoppers it can be shaped into endless forms.
