About how much resin do you use per coaster? These are great!

That is so beautiful. How much resin do you put in the sand so it looks so beautiful and not running. What paint do you use to get that lace in the waves.

How do you get the sand black ? Do You mix resin with black acrylic then you pour it on the sand ?

Can I use hair dryer if I don't have heat gun?
