Yes you can make a blackish goo. You just dump all the colors into the wax at heavy doses. Pretty much use all of it lol. They do make a purple that you can buy that should run black is you use all the dye pack.
The metallic is done by silver sharpie markers. You have to pull the marker a part and squeeze out the ink into the wax.
I emailed gookits about the black dye and this is their reply. Kinda funny.
"As soon as the labratz get to it. They have had the samples for a couple of months now. I"ll ring their ears about it again"
I ordered a kit and some purple dye for my Grande. It shipped the next day, EX. service. I'm going to try using all the purple dye. I hope it turns out (almost black) like the ones I've seen here.
well gookits wouldn't be where they are now, if the grandes were in good shape lol. The metallic look is done by Silver Sharpie Marker ink. You have to open up the markers and squeeze out the ink into the wax in. You usually do this while the wax is still in the gookit container. I just did my first metallic grande lamp and it took a total of 52 markers.
supposedly the goo kit peoples are in the process of remaking the black dye and are going to re-release it someday. However I've been waiting over a year now.
Thanks! It can get messy so wear rubber gloves and make sure you mix the wax and ink PRIOR to pouring into the globe. This is permanent marker after all and it will leave marks on or in the globe if your not careful.The metallic method came from someone who stopped by here about a year ago, he made his own goo and used the metallic sharpies to color it. And I tell ya, a lot of us here were super excited to hear this, because most of us have been trying for years to make metallic wax and we could never find out how to do it until this guy came along. He did warn us about using too much ink, because it would cause the wax to stick to the globe. But I think I got the amount of markers you use down pretty good where is looks very metallic and causes no sticking.
Havent tryed but it might work - depends on the type of wax the gookit dye is made from and how compatable it is with the vintage lamps.
What lamps are you intending to cloure.
