FLASHING : The application of a very thin layer of glass of one color over a layer of contrasting color. This is achieved by dipping a gather of hot glass into a crucible containing hot glass of the second color. The upper layer may be too thin to be worked in relief. After the piece is dipped in glass of a contrasting color, it is blown to final form.
Cased glass: see Overlay glass:
A technique of putting successive layers of different colors of glass over an object. Sometimes cased glass is cut away to expose the layers of color. The term plating as a synonym for casing appears to be an North American term. The term "cased" is mostly used in Europe.
I recently bought some dried gourds to use as substrates for some mosaics. After completing the first one, I realized I needed something flexible to use so the gourd wouldn't tip/wobble while working on it. I had one of those 'pool noodles' that kids use and for which I repurposed into a grouting tool (works really well for that, btw) and I decided to make a ring out of it. The beauty of this is that you can vary the size depending on your substrate. Basically, I took about ten 2" pieces of 'noodle" and strung them together.

At the top, in 2009 February making my mixture substrate test in 4 Echinopsis "brothers". At the bottom, Echinopsis after 10 months (2009 December). You can see the different level of growing and differents behaviours.
Notice the details: a black coyote chasing a brown jack rabbit; an elf owl inside the saguaro cactus; mountains colored pink with the sunset; a colorful rattlesnake slithering behind a rock; a purple hummingbird finding a wildflower; a black & yellow gila monster (crayon in the background); rocks and "sand" (oat bran) as substrate.
Used a loose mix of thinset,
not quite "peaking" consistency.
Used my hands to trowel it as
smooth as possible.
Left to sit an hour or so and then
Tooled further by gently rubbing the surface with my palms.
Substrate: Quercus robur.

this animal was recently recontextualized for me in a very interesting way. C. pyrrhus are known to be very good substrate-matchers, and rattlesnake camouflage coloration is known to affect predation rates. the balance among possible mechanisms that achieve this at the meta-population, population, and individual levels is not explored; it could be behavioral, it could be evolutionary, (i think) likely it is a combination of those two. this individual was seen in an area where most animals are vibrantly yellow, and most animals that are not yellow are gray and tan, and this biphasic locality exists as a tiny unique pocket within a (much) larger, mostly-monophasic (the gray and tan phase) region, and this is at the western edge of the species's range (range edges are often where genetically-weird stuff happens, both because range edges tend to occur near to where tolerance limits occur, and because there's less convergent selection on subpopulations on edges relative to subpopulations that are receiving gene flow from all directions). this individual seems to me to be representative of the regional gray and tan phase, but in which something to do with the concentration of melanin in the ectoderm has been amplified, to cover the animal in black spots so dense that the animal looks black when received as a whole. this can probably happen by accident (it's not quite melanism or hypermelanism the way that that is usually expressed in snakes), and for a long time my interpretation was that it was just an accident... but last time i visited this site, i found out that less than 20 years ago, a very large area around the site had burned in a wildfire. burn scars still persist in the area; a visitor can see burn marks on old woody stems in the area, and ash stains on many rocks... 20 years later. 15 years ago? 10 years ago? maybe even 5 years ago? for a long time the dominant substrate color (i would guess soils and rock faces) was probably black. certainly this is not proof that the local subpopulation evolved or chose (or a combination of these) substrate matching to a black, wildfire-generated substrate, but the idea is thought provoking.

Divers Kate and Chuck ready to release a concrete substrate from the davit and escort it down to the bottom. Back to UAB in Antarctica website.
White Mountains cinquefoil, Potentilla morefieldii, elevation 3530 m (11580 ft). Substrate is carbonate (Reed Dolomite).
This species is endemic to the high subalpine and alpine of the White Mountains, and to a small segment of the Sierra Nevada directly to the west across Owens Valley. Named by Dr. Barbara Ertter in 1992 (Brittonia 44: 432-434) as part of her work to sort out the variation in the Potentilla drummondii/breweri complex, it was previously misidentified by me and others as P. drummondii var. bruceae or P. pseudosericea. It will forever be an honor to have an eponymous species residing on top of my favorite mountain range!
Repeated alternate steps of applying gesso then sanding smooth to produce a strong white matt surface for acrylic painting (it's better to do this before the sun goes down, if your lights are rubbish).

Although common on sandy soils, this annual inhabits other substrates such as cinder beds, rocky soils, and bedrock. This could be Cryptantha torreyana, which is similar in appearance but grows on non-sandy substrates. The lanceolate nutlets or fruits of this plant, however, are those of C. fendleri, which is common through this part of the Snake River plains. This site lies along the North Crater trail on the south side of Big Craters, Craters of the Moon National Monument, Butte County, Idaho.
As the scientific name implies, gray tree frogs are variable in color owing to their ability to camouflage themselves from gray to green, depending on the substrate where they are sitting. The degree of mottling varies.[3] They can change from nearly black to nearly white. They change color at a slower rate than a chameleon. Dead gray tree frogs and ones in unnatural surroundings are predominantly gray. The female does not croak and has a white throat; however, the male does croak and has a black/gray throat. The female is usually larger than the male.
They are relatively small compared to other North American frog species, typically attaining no more than 1.5 to 2 in (3.8 to 5.1 cm). Their skin has a lumpy texture to it, giving them a warty appearance. They are virtually indistinguishable from the Cope's gray tree frog, H. chrysoscelis, the only readily noticeable difference being their calls. Cope's gray tree frog has a shorter, faster call.[4] The gray tree frog also has an extra set of chromosomes (4N), or 48 in total, and is called tetraploid gray tree frog in scientific circles. The Cope's gray tree frog, or diploid gray tree frog, retained its 2N (24) original chromosome set. Hybridization between these species results in early mortality of many larvae, but some individuals survive to adulthood though they have reduced fertility.[5]
Both H. chrysoscelis and H. versicolor have bright-yellow patches on their hind legs, which distinguishes them from other tree frogs, such as H. avivoca.[6] The bright patches are normally only visible while the frog is jumping. Both species of gray tree frogs are slightly sexually dimorphic. Males have black or gray throats, while the throats of the females are lighter.[7]
Tadpoles have rounded bodies (as opposed to the more elongated bodies of stream species) with high, wide tails that can be colored red if predators are in the system. Metamorphosis can occur as quickly as two months with optimal conditions. At metamorphosis, the new froglets will almost always turn green for a day or two before changing to the more common gray. Young frogs will also sometimes maintain a light green color and turn gray or darker green after reaching adulthood.

Comments: Pluteus pouzarianus belongs to Pluteus cervinus agg. Variability of size, color, etc. of members of this group is so big that several authors claim they can hardly be determined in the field. Microscopy is needed. Pluteus pouzarianus is distinguished from other options, particularly from common Pluteus cervinus s.s., by: about 40% of hypha in pileipellis having clamps and it grows exclusively on conifer wood. Usually it has (in average) grayer cap and it is of somewhat smaller size. It seems, traits of the find fit well to literature.
There were two pilei present in this find. Pilei diameter 4 and 4.5 cm, surface velvety-waxy for palpation, cuticle peels off easily; stipe 4.5 and 5 cm tall, diameter in the middle 6 and 6.5 mm, 'bulbous'; smell faint, lightly on radish; taste faint, slightly mushroomy and on radish; SP abundant, pinkish-ocher, oac651.
Spores smooth. Dimensions: 6 [6,8 ; 7,1] 7,9 x 4,6 [5,1 ; 5,3] 5,7 microns; Q = 1,2 [1,3 ; 1,4] 1,5; N = 33; C = 95%; Me = 7 x 5,2 microns; Qe = 1,3. Pleurocystidia numerous, horned.

Mud-puddling is the phenomenon mostly seen in butterflies and involves their aggregation on substrates like wet soil, dung and carrion to obtain nutrients such as salts and amino acids. This behaviour has also been seen in some other insects, notably the leafhoppers.
Lepidoptera (butterflies and moths) are diverse in their strategies to gather liquid nutrients. Typically, mud-puddling behavior takes place on wet soil. But even sweat on human skin may be attractive to butterflies.The most unusual sources include blood and tears.
This behaviour is restricted to males in many species, and in some like Battus philenor the presence of an assembly of butterflies on the ground acts as a stimulus to join the presumptive mud-puddling flock.
In tropical India this phenomenon is mostly seen in the post-monsoon season. The groups can include several species often including members of the Papilionidae and Pieridae.
Males seem to benefit from the sodium uptake through mud-puddling behaviour with an increase in reproductive success. The collected sodium and amino acids are often transferred to the female with the spermatophore during mating as a nuptial gift. This nutrition also enhances the survival rate of the eggs.
When puddling many butterflies and moths pump fluid through the digestive tract and release fluid from their anus. In some, such as the male notodontid Gluphisia septentrionis, this is released in forced anal jets at 3 second intervals. Fluid of up to 600 times the body mass may pass through and males have a much longer ileum (anterior hindgut) than non-puddling females
