Effetre Spanish Leather is a streaky, stable dark reddish orange colour. It reminds me a lot more of ripe tomatoes or hot chili peppers than leather -- if the name had led you to believe that this colour was in any way brown, it has tricked you.
Spanish Leather behaves fairly predictably as compared to other reds and corals, although the consistency is a little stiffer than Coral and the texture less 'grainy' if that makes sense to you. It is a bit of a striker, and when it is allowed to heat and cool repeatedly, it can turn quite dark. You can see this on the ends of some of the beads as you look through the rest of this post.
Spanish Leather does not develop any noticeable effect from being introduced to a reduction flame.
Silver has a very interesting appearance on top of Spanish Leather, turning blueish in some places and yellowish in others, and hazing a little on the surface. When the silver is reduced and encased, the interesting effects are lost and you are left with just a silvery net effect on top of the dirty brown Silver/Spanish Leather reaction.
Silver Glass likes being on top of Spanish Leather. In both beads, a strong brown/black line has developed around the fritty bits. You can see in the bead on the left that I got nice pinks and purples from the TerraNova2 frit. It's too bad it sort of clashes with the Spanish Leather itself and that the colours don't gel better.
In the bead on the right, the reducing silver glass also developed colour nicely and because the blues of the silver glass has good contrast with the base, looks quite nice on top of Spanish Leather.
When Spanish Leather is used on top of Tuxedo, a shiny, greyish line appears around the dots and stringer lines. This line is lighter and shinier than the line that pops up around it on top of Copper Green.
Spanish Leather and Copper Green have a reciprocal dark line reaction between them.
Ivory spreads out a little on top of Spanish Leather, but apart from that not much of interest occurs between Spanish Leather and Opal Yellow, Ivory, or Peace.
This sculptural goddess bead was made with Spanish Leather, and illustrates the richness and streakiness of the colour.
