=============================================================
Turned Form Definitions
Bowl â€" Rim opening is the max diameter of the piece +/- 10%. The height of the rim is 25% to 75% of the max diameter of the piece.
Plate â€" Much like bowls expect the height is less than 25% the diameter of the piece.
Platter â€" Big Plate
Dish â€" small plate but height might exceed plate percentage yet avoid bowl proportions.
Hollowform- The opening is equal to or less than the foot diameter. Hollowed to consistent wall thickness.
Openform â€" The opening is at least 200% of the foot diameter but significantly less than the max. diameter of the piece. Hollowed to consistent wall thickness.
Closed Form â€" features an opening between a Hollowform and an Openform.
Vase â€" a bowl or an open form where the height is 2 times or greater of the max diameter. Hollowed to consistent wall thickness.
Urn - hollow form where the height is 2 times or greater of the max diameter. Hollowed to consistent wall thickness.
Jar â€" Rim opening is the max diameter of the piece +/- 10%. The height of the rim is 200% or more of the max diameter of the piece. Hollowed to consistent wall thickness. May have lid as part of design.
Pot - Rim opening is the max diameter of the piece +/- 10%. The height of the rim is 75% to 125% of the max diameter of the piece. Hollowed to consistent wall thickness.
Box â€" A lidded vessel, generally small
Art Bowl or Thick Bowl â€" a bowl or dish where the inside shape and outside shape are unrelated,
Natural Edge â€" Any edge left by nature that remains on turned form. For example bark, surface under bark or the ID of a hollow tree. Natural edge can be left on any of the above forms.
Bonus Definition:
Woodturner â€" A dusty but kind individual prone to long hours in solitude. May be often found doodling shapes when not in his shop. Likely to stop suddenly for downed trees. Car smells like gas from the chainsaw in the trunk. May drive mini-van despite not having kids and/or dreams of a full size pick-up truck. Seldom purchases gifts for friends or family but would rather offer items he has created. He vacations in less popular American cities such as Louisville, Portland, Richmond, Brasstown or Provo. When his wife asks what he is doing on the internet and he answers ‘Looking to get wood’ she doesn’t worry about their marriage.
