We have consulted with a member of our hot glass team and he suggested you may want to try cork. I have attached an article which may be of use to you. Regarding recipes/ratios for sawdust I have been unable to locate this information in a basic search of our holdings. Please let me know if you have any additional questions.
Best of luck with your research
