Is it possible to use common household ingredients to create resin? Not sure, if possible, but from my understanding, we often buy resin and hardener from shops, and then mix them before pouring into mold tray.

So, I was wondering if we can use common household ingredients (such as soda carbonate, white glue, the list is non exhaustive but are items that is commonly found in a house) to create non-toxic or less toxic resin, to be used in mold tray.

So, is it possible to use common household ingredients to create DIY resin?
According to Wikipedia, resin is:


  In polymer chemistry and materials science, resin is a solid or highly
  viscous substance of plant or synthetic origin that is typically
  convertible into polymers. Resins are usually mixtures of organic
  compounds. This article focuses on naturally-occurring resins.


The article references plants which secrete resin for protection. The synthetic aspect of resin covers epoxy and polyurethane resins, more commonly used for casting.

It is likely that you would be unable to create sufficient quantities of plant based resins for casting in molds.

As a more generic answer, one could use gelatin to cast items, but the physical properties may be insufficient for your purposes. Gelatin is not known for durability nor for physical strength.
