I recently made some rings using 2 part epoxy and sawdust/wood leavens. They looked beautiful, but, they became playable with body heat. Can I increase the ratio of hardeners for a more stability/hardness?

No. The mix is what it is. You would have to look at different types of epoxy.

Another thought, if you are molding, maybe try CA glue.

No, you can never alter the ratios. Here’s a good primer on epoxy.

If you alter the epoxy by adding more hardner it will become brittle.

Use good epoxy. Throw out the 5 minute stuff. Use epoxy that sets up in 18-24 hours. I like Miiller Stephenson, but I don’t know if they sell less than quarts. Another good alternative for smaller quantities is Golfsmith 18-24 hour shafting epoxy. Both have good shear resistance, so they can stand some flexing.

Thanks for the responses. I don’t know why the epoxy becomes soft with body heat. I used envirotex bar top epoxy. Maybe it was old. Maybe user error. I am looking to make a yarn bowl (no lath). I want to make a slurry of wood stuffs and glue/epoxy and pour/mold it over a bowl.

I have used West Systems Epoxy for several years on preserving wood, repairing window sills, and on my sailboat. I have a problem with anything that has to be mixed. The West Epoxy always works as the pumps for the resin and the hardener are calibrated so one pump on the resin equals one pump on the hardener. I never vary the ratio. I have had great success. I built some panel raised Victorian style newels for our porch. I saturated them with epoxy. We’ll see how they hold up.
