Modeling for your cast usually takes 30 minutes . it can be messy but is painless and fun. I do prefer to meet with clients early to establish the pose they want and are comfortable with. Once posed my assistants will apply alginate ( much the same as a seaweed wrap at a spa ). Dental plaster is painted over the alginate to form a hard shell. This is removed, we have a perfect impression of you in the alginate and you are free to leave. Layers of sculpting hydrostone are then built up in the negative mold to form the positive cast. The cast is then trimmed and sanded etc. You can leave it white or choose a variety of finishes.
