Do you still help out manufacturers of plastic pencil to improve their recipes with a view to match the charecteristics of plastic pencil with that of a wodden?

That work was done in the early 1970s. I am now retired and no longer have access to a lab or the materials that would be needed to carry out such work.

Many thanks for your prompt response, Can you share with me the last working recipe?

If you look up the patents, they both give the approximate formulas that we used to make the pencil sheath.

I'm afrain the link for the second patent isn't working right now, and I haven't been able to fix it, but if you go to my other blog -- ADL Chronicles (

I believe the links are working.

Why are the epcon process pencils not available in us anywhere?I have looked in every possible store.One would think, in our enviromentaly aware society,the epcon would be around everywhere.

Eric, our work for Empire Pencil was done in the early 1970s. The company did produce the pencils for several years, but Empire was bought by another pencil company and ceased production of the Epcon pencils.

Plastic pencils are still made in Asia, but I'm not sure why they are not marketed in the U.S.
