I did some cuttle fish casting earlier and I’d like to share the process with you. I really like the natural pattern and the material. AND > It is a great way to use up your scrap silver.

How do you make a silver cuttle fish casting? You start by going to a pet shop and buy at least 2 cuttle fish bones. You need some sandpaper a flat surface, files, masking tape and lots of heat.Sand the cuttle fish bones until they are flat and fit together perfect. Than with a file make the shape in one of the bones you want to cast, here just a plain rectangle. With a cutter make a gutter around the chosen shape. This is to let the air out when the silver goes in. Also make a V-shape in BOTH bones to poor the silver in later, about 4 cm or 1,25 inches in size.

Brush the bones to get more detail in the wavy pattern. Make extra tiny vents from the chosen shape to the gutter/air vent.

Sprinkle both sides with a pinch of BORAX powder. 

Tape (masking tape works fine) the 2 sides together, make sure there are no other holes than the V-shape. (Hold it against the light to check) Than set it up, ready for casting. Melt enough silver for the cast, better too much than too little :-) Here a small kiln is used and a torch to speed up the melting, but you can use just a torch by itself as well.

This is the cast, cut in half and the left side has been rolled. This is an option if you want to make your cast a bit bigger by rolling it, it will flatten the pattern a bit, as you can see. If you flatten it altogether, you will have a fresh sheet of silver.
