  • There are three types of drawing paper, here they are: Cellulose paper has an acid content that will destroy the paper over time. The more acid content it has, the shorter its life expectancy. To combat this problem, buffers are added to these papers. The buffers keep the acid from destroying the paper as quickly. Completely buffered papers are referred to as being PH neutral. Combination paper is usually referred to as having some percent of cotton rag content. The higher the cotton rag content is the longer life your paper will have. **Cotton papers are 100% cotton. They are referred to as being 100% cotton rag. Not all cotton papers are equal in quality, though. Some cotton papers are made from the inferior shorter cotton fibers. When you work on these papers intensively, they can start to get fuzzy. Cotton papers made from the longest cotton fibers are the best. They can withstand lots of erasing and working without showing any wear at all. The life expectancy of 100% cotton paper is well over one hundred years.
