Works very well for making a great potting compound.

This is a great product that has been around for many years. If you need a mold for use in plaster of paris, look no further. This is the deflocculant for you.

Pros
  • This is great
Cons
  • Some bugs

Spelled in a box

Just received my order, 3 Darvan 7 one of them looks wired not as clear as the others. Two of them are written in boxes, one of them is sharp.

Pros
  • For deflocculating flame retardant white clays
Cons
  • Very expensive
