FD&C Blue 1 Alum Lake

Worked! Nice and intense.

Great product

Very very excellent and strong pigment of blue, very good and savory in small quantities also since the pigment can be very strong, I know it sounds common but a little is really all you need for a lot of color. Great blue though this pigment does also have some trouble being completely soluble in water and due to the dye being so powerful it will stick do almost anything which can be both good and bad at times especially if you want to avoid any sediments.

Easy to grind and a very lovely shade of blue!

Wonderful
