Gatekeeper: "pure" means more like "homogenized" when referencing the type. It's not like an element is a homogenous. "pure" energy can be a mixture of potentials. As they cool down these "potentials" begin to get closer together. Or maybe a better way to put it is they begin to interact.

I had forgotten the proposed experiment hadn't been done as yet. My feeble brain making assumptions. But a photon is a discrete particle in tqhe zoo of particles. But the major problem in my discussion with dhw is that it is not clear to me where the demarcaton for matter begins. And I think dhw is confused by what I have described. Penrose in The Road to Reality defines energy as discrete bundles or quanta, but offers no definition of matter. The Strassler article defines particles' masses as GeV (Giga electron volts) measurements of energy, about the energy of the hydrogen atom. -http://profmattstrassler.com/articles-and-posts/particle-physics-basics/the-known-apparently-elementary-particles/-So I guess, if an electron is the proper beginning of matter from the clumping of quantum particles of less energy than an electron, that is the definition.-My problem, as I see it, is, I have been reading lay interpretations of the story of the universe and it has changed. In the early days, the expansion of the universe lead folks like Hawking to propose a singularity and lots of heat.The Guth developed the idea of inflation and published a lay book about it. Things have changed in the interpretation. Instead of a singularity and then inflation, now a quanticized version is that something started inflation, then there was the hot big bang with tremendous heat that made all the energy into a plasma, which lasted around 230,000 years, and as it cooled reached the current temperature of the CMB of 2.7 Degrees K. And finally, as you point out, with the cooling, various quantum particles began to appear and they finally clump together to make matter. But both descriptions of the beginning of the universe describe all matter as being quantum particles, therefore, simply a more solid form of energy.-And then to mix in the timing issue, the cosmologists, in their equations, can't find a 'past' before the appearance of inflation, and according to Vilenkin this applies to our universe and to all multiverses (in a paper just a few months ago). There is a beginning to the reality we have now.
