Drawing tools
·Paper:
Important qualities: colour, thickness and size.
Thickness is measured by the weight of 1 m2
,
GSM, which is grams per square metre.
Size in Europe is measured in A format:
A0= 1 m2
, if you fold it in two (by the longer
side) you have 2 A1 sheets of ½ m2
.
Typical notebook sheet is A4.
How many A4 pages can be made from 1
single A0?
·Pencil:
Classifed by hardness of the lead:
B -> Black (soft).
6B is harder than 2B.
1B
doesn’t exist, it’s just B.
Perfect for artistic
drawings.
HB-> Medium and Black.
For sketches and normal draftings.
H-> Hard.
6H is harder than 2H.
1H doesn’t
exist, is H.
For technical drawings (plans).
Hardness List (from soft to hard):
Soft: 6B, 5B, 4B, 3B, 2B
Medium: B and HB
Hard: H, 2H, 3H, 4H, 5H, 6H
·Propelling pencil:
Classified by hardness (like pencils) and
diameter.
Typical ones are 0,5 mm across.
·Eraser:
Made from rubber.
They must not stain the
paper.
·Fountain pen:
Like pens and ballpoint pen
