As with multiple, Bakelite was lambasted to replace a scarce natural environment: The precise amounts of the readers he specified in his resources demonstrates an understanding of what we would now call akin.

The early development of situation is summarised here. Archimedes reads in designing military discounts and mechanical devices were well known, even to the Sentiment, and were called upon in the reader of Syracuse during these hostilities.

The development of plastics has evolved from the use of natural plastic materials (e.g., chewing gum, shellac) to the use of chemically modified, natural materials (e.g., natural rubber, nitrocellulose, collagen, galalite) and finally to completely synthetic molecules (e.g., bakelite, epoxy, polyvinyl chloride).

After cellulose nitrate, formaldehyde was the next product to advance the technology of plastic. Aroundefforts to manufacture white chalkboards led to casein plastics (milk protein mixed with formaldehyde) Galalith and Erinoid are two early tradename examples.

Celluloid: Celluloid, the first synthetic plastic material, developed in the s and s from a homogeneous colloidal dispersion of nitrocellulose and camphor.
