BoroImage Application Technique
Have you tried working dichroic images before, and met with limited success? We've compiled a few tips which will hopefully help you to bypass the frustration of trial & error and expedite the rewards of working with these truly amazing materials.
Begin by wiping the image clean, making sure it’s free of any oil from your hands.
Attach 3mm rod to one corner and proceed to heat the back side of the image with a soft flame. *CAUTION avoid direct flame exposure to the dichro coated side (just a couple seconds can burn the image).
Use the same size clear rod as the Dichroic Alchemy image for encasing, that way you don’t have to gather your clear rod. Instead you can just warm it up, make it pliable, and then smash it on the image. Never smash white hot glass on an image because it will distort the fine detail that the incredible laser technology has brought to the table. Wait a moment until the 10mm clear rod has cooled to a dull orange or red color.
NEVER PUT A WHITE HOT GATHER ON TOP OF THE DICHROIC IMAGE BECAUSE IT WILL DISTORT THE FINE LINE DETAIL.
Push 10mm rod down on top of the image. It’s very important to only push 10mm rod until it creates a circle that encapsulates the dichroic image but stays flush with the rest of the dichro “square”. So if correctly applied, the corners of the images will still be sticking out.
After that step has been perfected, you need to get the square corners of the image to become a circle. Flameworker logic says to heat up in the flame and melt down the edges into a circle but dichroic logic says that process would distort the image. Instead, take a 3mm clear rod and put the image marble way out in the flame (dichro sweet spot is usually 6 or 7 inches from your torch) and without giving much heat to the 3mm rod, heat up the corner edges of the square image and use the 3mm to lightly SMEAR the edges.
Now that you have a circle you should apply color by gathering a ball of color and pushing it into the image on the opposite side that the 10mm rod is on (I recommend applying color up to the edge of the dichro square itself to hide any imperfections).
THE KEY TO DICHRO SUCCESS: HAVE YOUR OXYGEN REGULATOR TURNED UP TO 40 - 60 LBS
Using this very oxidizing cool flame, slightly heat the marble and use a carbon paddle to roll all the un-smooth parts out of the sides where color meets clear.
Finally, it is very important to finish up the shaping process with a marble rounder / carbon paddle to avoid unnecessary heat being applied to the dichro.
