What if you were to dip the shrimp in slip several times (dry between dip=

s) and then fire it? Calcium carbonate makes up most of the body "shell"=
=3D
of a shrimp. When you fire a seashell, you get a soft pile of white powde=

fired slip may be strong enough for you to gently cast a mold. (On the=

other hand...shrimps are cheap...you could just dip a new one in slip and=
=3D
apply to your wares each time you need one.) =3D20
Or...you could use the shrimp body dipped in a glaze as a "stamp" - like=

Dear Paula Rutledge,
What you say it correct for molluscs but it is not true for animals of the
family to which shrimps, lobsters and crab belong . Their carapace, or
exterior skeleton, is composed of a substance called Chitin, an insoluble
nitrogenous polysaccharide which is the main constituent of the exoskeleton
of arthropods.
When I required Sea Horses for a project I impressed dried specimens into a
fine grained plastic clay tablet which was bisque fired. This proved most
durable for taking sprig moldings.
Were I to require mouldings from shrimps I would use the same process.
P. Whitford and G. Wong give a good account of the Sprig making and
application processes in "Handmade Potter's Tools" (2 nd Ed 2003, ISBN
0-9733565-0-2 )
