Great course that covers the process in detail. Very clearly explained and demonstrated. There seems to be a lesson missing in unit 3 between casting and bisque firing. The cast needs to be cleaned - the join marks tidied - and where is the part that turns the one piece cast into a lidded pot with leaves on top? I am confident enough to be able to do this myself, but those with little experience may not be. Hopefully this missing part can be addressed in future. Otherwise an excellent course.
This was a very thorough course. Fantastic detail. I am able to create what I need now
Muy útil para replicar piezas. Buena profesora
El curso es muy interesante. Me gustaría una segunda parte, hay mucho que aprender acerca de moldes.
Divertido para investigar, no sé si es el mejor lugar para arrancar, creo que para este tipo de cosas es mejor ir a un taller.
