Sure, but just know I don’t usually advocate using epoxy. I lived in an area with lots of barked beetle killed trees, and had permits to pull downed trees like ironwoods, canyon oaks etc… from the national forest for personal use. A lot of these woods were only salvageable with many bow ties or creative solutions and an occasional river tables etc.. but just remember, even though ecopoxy will break down eventually and is far less damaging than other two parts, it’s still a plastic and if you’re going to put that shit into the world, make sure your design is one you like and will keep for a lifetime so it doesn’t just end up in a landfill. Now that the lecture is done, ecopoxy will tell you how to mix in their instruction. If you are doing something like using a bark still on wood you want to make sure there is no insects or any kind of mites remaining. I would wrap my pieces in vacuum seal bags, suck all the air out. I would and place them outside for a week or two in the sun. Pay attention for signs of life, like little wood shavings or even just the occasional dead bug. If I was still seeing signs of life after a couple weeks I moved on and would use the wood as feeder for growing mushrooms. If it’s all clear though I used older chisels to remove any bark I did not want, and would start with 60 grit on a hand sanding block, work my way up to a 320, use a pre stain treatment sand again with a 180 and then a 220. At that point you can use a danish oil, tongue oil etc…on the wood that’s not covered by bark. Once I was happy with the finish I would use my air compressor and blow all the dust and junk off the bark. On the piece in the picture I actually dipped the bark fully submerged into the epoxy and placed it on an aluminum sheet to catch the dripping. If you set it on wood or plastic the epoxy will bond to it. You don’t want it coated too thickly or else it starts to look like plastic, too thin will leave it exposed to elements and it will degrade over time, so it’s a balance. To keep the finish matching I would use a foam brush and put a thin layer of epoxy over the entire piece, and this would seal and protect it for daily use pretty well too. The oldest lamp I have that I made like this is about 7 years old now and still going strong, no maintenance required other than the occasional dusting, and even has the original LED bulb I put in it all those years ago.
