Effetre Petroleum Green (EFF218) is a pretty teal green opaque colour. I had never really used it before I made these beads and some things about it really surprised me.
The things that I found surprising about this colour will maybe not come as surprises to you. For one thing, this colour is very, very streaky. You can see streaks in it when you make simple spacers, and it separates like mad on top of just about everything. It's also very soft -- much softer than using other opaque teals like CiM Mermaid and Effetre Marine Green will prepare you to expect.
Silver isn't very interesting on top of Petroleum Green until you reduce and encase it and it turns a bright mustard colour. Petroleum Green has this yellow-with-silver-under-clear thing in common with Copper Green, Light Teal, Light Aqua, and Celadon.
Unfortunately, encasing the reduced silver will crack your bead. If you've made beads before with Petroleum Green and silver and then encased your beads with Effetre Super Clear only to find they cracked... well... me too.
As I mentioned already, Petroleum Green separates on top of everyhing. It also gets a creeping brown reaction line with Ivory that is not very uniform.
Opal Yellow and Copper Green both separate on top of this colour.
Here are some beads made with Petroleum Green.
