Chalk carving
From Wikipedia, the free encyclopedia
Chalk carving is essentially carving in chalk. This article covers some methods, types of chalk, tools used and the benefits (and ramifications) of this material.
The benefits of this material are also its ramifications. Its main benefit being its softness making it very easy to manipulate. This is also a serious disadvantage, as this causes chalk structures to be very delicate. This material is also extremely brittle and dusty. However it is cheap, readily available, easy to work with the simplest of tools, and able to hold a reasonable amount of detail.
The main types of chalk, for the purposes of the carver, are processed and non-processed (natural). Processed chalk has several advantages over natural chalk; it is softer, more consistent and comes ready finished in neat cylinders (of varying sizes). However, natural chalk is available in more interesting shapes, the size is not limited, and it holds detail better.
Tools for chalk carving are numerous. In fact any small file, stone carving equipment (no mallet is needed), and even needles can be used. Some of the best hand carving equipment are an etching needle, a selection of small files, and a miniature carving tool designed for soapstone.
The methods are very simple. Once the carver has a feel for the material, it is possible to construct fairly complex shapes, and make figurative work. It is possible to coat the chalk in button polish to produce a finish.
