Starwest BotanicalsFullers Earth Powder (453.6g)

Have you heard of Fuller's Earth Clay, being used as a hair straightener.

Will it Tighten skin

How would you clean this up when sprinkled on wood or fabric like fake dust? It seems to spread.

How finely milled is this? Is it pretty gritty or does it feel like soft powder? I'm hoping this will make a good detoxifying face mask.
