    I for one, appreciate Joe's efforts, he is a great bloke to chat to as well, he has been around a long time in the business and has seen all the chemicals and understands how they work, most of which i could never even pronounce. He finds time to help out on the forum, send out orders, develop new colours, and hardest of all, puts up with Trevor stirring him up every chance he gets

    Keep up the good work, and try not to pull out any more hair with the issues that one member is currently having, i hope it's something simple causing the issue.

    Is there any chance that a majority of the pigment has settled to the bottom of the jar of coating? Yet they were blue before cooking, so it does seem to have been dispersed.

    I am taking some from bulk pack, and sending you a small jar of the US batch.
    More samples will also be included, as I have some other colours to try out.

    To answer about TRUBLU colour, it is not all that sensitive, as long as it is not over baked and at higher temperatures. The Blue is not what changes, but Resin binder system starts turning Yellow to Tan. So when you mix Yellow with Blue you get green. Depending on just how and type of green the coating gets, will directly be governed by how much combined overbake and temperatures the coating is exposed to, and what resin binder colour ends up finally to alter the Blue colour.

    With that single member who is having colour problems with TRUBLU, the pictures I have seen worry me. Colours looked to me to go from Blue to nearly Black. I don't know if it was bad light, or what I saw was accurate.
    I believe that Donnie is sending him another sample out of another batch to test. We will see what happens with that one.

    Ah, that makes sense. So in theory, something like old gold that Petander uses is not as susceptible due to being a yellow already, but of course, if you bake the poop out of it, it will get darker with the yellow to tan colour of the over cooked binder. He has shown that is the case and that it still works a;; the same.

    I think i'm going to have to hit you up for some Tru Blu, it does look nice

    You are correct.
    All the colours (aside from Blue and Black) all have the yellowing of Resin affect final colours. Some more than others.
    Some colours are more transparent and others are less transparent. The final colour effects are not linear or equivalent across all coatings. That is why it is always suggested, that people manufacture, so product works OK, passes all tests, and results are reproducible every time with equipment used, and are happy with final colour..
    What makes life very difficult is the huge variations in equipment, and conditions people are exposed to, with trying to produce consistent results.

    That is so very true, especially ovens, they all heat differently. You get to know how long to cook and where to put the projectiles and how many to put in. All i could think is it's a radiant heat issue over heating them, but he has done temperature readings that say that is not the case.

    The 122 red i use for one particular person comes out perfect every time. It darkens slightly, but comes out the same every time if i follow the cooking times @ 200c

    Joe,

    It’s definitely not black, but dark emerald. I will get some pictures in sunlight tomorrow to eliminate as much artificial lighting color effect as possible.

    To everyone else, I am in no way being critical of the product or anyone involved with it. I feel like I am on a R&D team working on a new product and I am taking up the role of a field tester just reporting back findings. I have an Aerospace Engineering degree and now manage software development teams, so I am very detail oriented and thorough. I hope I don’t come across as being negative or disgruntled. I think this HI-TEK is some awesome stuff and I have no complaint and am just trying to get it right.

    If the binding carrier turns amber, blue turns green every time. I’m just hoping I can figure out why my process is driving it to amber when others are having more success. The blue is sensitive and if I figure it out, I’m hoping what I’m going through can ultimately help others. Unfortunately, it may turn out that the blue turns out to be too much trouble for Joe and he may ultimately decide it isn’t worth all the hand-holding necessary to sell and support it. I’m hoping my failures can lead to easier successes for others.

    It’s all good and I’m hoping for good things.

    Sorry for the rambling.

    Thanks Donnie! I really appreciate it. That is two coats of tru blu. Baked with the a.t.m. Coated bullets under a fan for around 10 minutes. On top of the oven until they hit 110 F. When the t-couple hits 360 F I started a countdown timer from three minutes. I used to use four but decided to try three. Works just as good. Use the same procedure with all the colors. Like I have posted before any of the hi-tek colors will look different under sunlight. The tru blu will take on a greenish tint.With the gold you can see the little sparkles in it. I will look different if I am in the sunlight. When Ausglock posts his results maybe he can shoot the photo outside. Whatever they look like that is what the color is. He is the final word on testing hi tek. RydForLyf,if I came across a little rough I apoligize. Everyone here wants to see you succeed.
    Boolits !!!!! Does that mean what I think it do? It do!

    No harm, no foul. I’m here to learn and without having a physical sample in-hand for comparison, all we have to go on is pictures and we all know how imperfect that can be.

    I think you’d make a good lab partner.

    Yeah, photos can fool you. If you pm me your address I will send some bullets.

    Louisianan road trip. Good idea. Been wanting to meet Donnie. And I haven't had a good road trip in a while. Since we live not that far away from each other and are Auburn Alum would enjoy meeting you, too. I may have some scheduling problems but definitely doable if Donnie has the time. Been thinking for a long time how cool it would be to have a get together of the coaters here in the US just to get to know everyone in person and share ideas.

    Glad to see the man behind the post. Talk Joe into giving you a photo of him to post.

    While I work at it, it is by God's grace that it happens. So it is best I ask him what, how and when before I start..

    Many thanks. It will be good to do some comparisons and post some pics.

    Here are two pictures of the same bullets on three different backgrounds

    Uncooked first coat, cooked first coat, cooked third coat and cooked two coats. Hopefully the color is better.

    Here are my three temperature read outs. 360 is oven controller, 349 is secondary in-air probe 5” above tray. 366 is ATM bullet probe laying on basket. This temp reads a bit high because the entire probe isn’t designed for being placed in the oven like I am using it. A new probe is being sourced so temp won’t read high. Controller is hooked to fastest reading TC to minimize temperature lags.

    Slide, those blue cast of yours posted above, what mould is that it looks a lot like the 156gr Lyman I modified by grinding out lube grooves. By the way I think they look great. Regards Stephen
