Please Note: As this product is a very pure epoxy. And it acts in a similar manner just like pure honey (pure epoxies act similar to honey in that, during winter, honey is extremely thick and yet in summer, that same honey is very thin and runny). So, to it is with epoxies. And just like pure honey which sometimes turns into sugar, pure Epoxy resin can act in a similar way and develop crystals (usually in part A). This is not from faulty resin, but common thought is that it is from the cyclic hot days and cold nights when stored. An easy fix is to heat the jugs up in very hot water for about 30 mins and this will restore the resin to be perfectly clear. That heating is also a good thing to help remove air bubbles trapped in the epoxy due to transportation.

If I have to do a critical pour or application, as a tip, I heat the jugs in near boiling water the day before the pour and let them cool down for the day of my pour. Additionally when mixing the two parts, I decant into the mixing container by pouring down the side of the container using the lower viscosity hardener first, followed by the base resin. All this effort is to try to limit any possible air bubbles that could ruin the finished product. Even when mixing, I use a wide rule and do not even take it off the bottom of the mixing container. Mixing is so important to get the best results and can take 3 mins.
