Hi Mark and list,

After looking at the photos, I can not see and colour as described.

On the last photo at the bottom of the page it looks like a rainbow film,
similar to oil on water.

May I suggest something that I used on photographing small crystals.

Make a pinhole light source.

Get a sheet of cardboard 12 x 12 inches, put a small 1/4 round hole in the
middle.

Place a rather bright incandescent light globe directly behind the hole.

Position your tektite for photography in front of the hole so that the light
shines through it and illuminates it from behind while your eyes and the
camera are shielded from the glare.

Cheers for now, Kevin, VK3UKF.
