Making a decorative concrete mold from the cross section of a tree stone. In today's tutorial, we'll be covering a fairly complicated process but overall relatively straightforward. Here of taking an organic piece like a tree stump or an existing rock and making a mold of that to create some decorative stone. In this case, a stepping stone for my yard. Now, some of you who follow us on Instagram may already have seen a lot of this process, but here you're actually gonna see the full video process. And by the way, if you haven't already, be sure to check us out on Instagram @biddymoldsupply. So essentially, what we'll be doing in this video, we'll be taking a quick silicone waste mold off of a tree stump and then making a resin positive from that using ez-flo 60. And then once our resin is cured, we'll be prepping that and pouring a more permanent production mold using Polly's 74 20. And then, of course, that will give us a production rubber mold that we can cast concrete into repeatedly to make hundreds of stepping stones. So let's get started. Now, one of the first important steps in this entire process is releasing our original pattern. Now in this case, we're going to be using a piece of a tree stump that I quite literally stumbled onto on the side of the road walking to work one day. And I thought this would make some interesting stepping stones. I really like the bark texture. And one thing that bark texture presents as a problem for release is it's a very porous surface. So, in order to make an accurate mold off of that, we're going to need to release it very carefully. In this case, we'll be using the Polly's 2350 release agent. And...
