A template is half the profile of the piece being made and is cut out in a strong, thin material like plastic, wood or metal. The mold shaping the inside or outside is on a wheel and covered by a flat piece of clay. The wheel is rotated and the template held by the jolly against the clay shapes it by scraping off the unnecessary clay as it turns.Read more about: Card plate

JUG

ca: GERRA

es: JARRA

Jugs are utensils to hold, carry and pour liquid and can be made of different materials. They always have a lip to direct the liquid while pouring it out. Usually the lip and the handle are in line and on opposite sides, but they can be at 90º to each other. A jug can also be without a handle and is then held by the neck or the main body. To make a jug by turning is basically the same as a vase but it has a lip and can be with or without a handle.

JUG - For measuring

ca: GERRA Mesuradora

es: JARRA Medidora

Jugs for measwuring are industrially made in plastic or glass for measuring different substances, liquids, sugar etc. The height of the weight or the quantity of liquid that a product takes is marked on to the outside of it.
