In this BoneCast, we will replicate a dinosaur bone using simple non-toxic materials (alginate and gypsum stone).
'Dencrigel' was the alginate mark used to make the shape or mold. Each package costs between $ 12 and $ 15 (~ 440g) and you get it at specialty dental stores (ask your dentist!).
Keep an eye on the type of gypsum used. Use "stone type" gypsum, which is sturdier and not crumbly like ordinary plaster.
This is not the only and the most "professional" way of replicating a fossil. In this video, we try to use simple, cheap and least toxic materials.
If you want to read a replication guide using polyester resin and silicone, read this super didactic text from UFRGS: www.ufrgs.br/pa...
