Wood description

Fresh cut Wallaba is brown/reddish and darkens to dark red-brown with characteristic sticky oily stripes. The appearance of Wallaba is strongly influenced by the high level of dyes, tannins and gum (up to 30%). Excretions of these dyes and tannins leads to dark stripes and stains on the wood whereby the wood feels greasy and sticky
