While they are similar in a lot of ways, they are different enough that understanding when and where to use them, especially in renovations, is imperative. Their differences are not readily apparent to the naked eye. Plaster and stucco can both be applied much the same way, with the same textures and thicknesses, but the main ingredients in each are what make them different animals. Plaster vs Stucco Like I just mentioned, the ingredients are what make the difference in these two similar building materials. Both are made with an aggregate of some kind, usually sand of various sizes and textures. Both need water in order to mix everything together and activate the curing process. The big difference is the binder. My purpose is to help homeowners get their feet wet on the topic. Plaster Depending on what kind of plaster you have, you will have one of two different binders, lime or gypsum. Lime — Prior to the early s, lime was the primary binder in any plaster.

Hope you enjoyed this roundup…and… Happy New Year!!! TSA Screening Cards for Ostomates and those with Health Conditions Yesterday, the Transportation Security Administration TSA approved of a solution to help passengers with medical conditions such as Ostomy discreetly inform staff of their condition to avoid any potential communication issues. These cards merely state that you have a medical condition that may affect the screening: I have the following health condition, disability, or medical device that may affect my screening:

renovation or demolition project find out if the drywall in your home contains asbestos. Drywall installed pre may have asbestos. Until about , the tape and joint compound, or ‘mud’, used to seal the seams and fill gaps between drywall boards sometimes contained asbestos. Asbestos-containing material is safe if left intact.

Despite its relevance, the paleoseismic record of this region is scarce, hampering our understanding about the relationship between the Andes building and earthquake occurrence. In this study, we used the U-series disequilibrium method to obtain absolute ages of paleoearthquake events associated with normal displacements along the active Mejillones and Salar del Carmen faults in the Coastal Range of the Atacama Desert of northern Chile.

The Th— U disequilibrium ages in co-seismic gypsum salts sampled along the fault traces together with marine evidences indicate that earthquakes occurred at ca. When coupled with paleoseismic marine and radiocarbon 14C records in the nearby Mejillones Bay evidencing large dislocations along the Mejillones Fault, the geochronological dataset presented here is consistent with the notion that gypsum salts formed during large earthquakes as a result of co-seismic dilatancy pumping of saline waters along the major faults.

Based on maximum observed cumulative vertical offsets in the studied faults, this phenomena could have occurred episodically at a rate in the order of 1: The results presented here reveal that the U-series disequilibrium method can be successfully applied to date the gypsum salts deposited along faults during seismic events, and therefore directly constrain the age of large paleoearthquakes in hyperarid and seismically active zones.

The distinction between the Paleozoic and the Mesozoic is made at the end of the Permian in recognition of the largest mass extinction recorded in the history of life on Earth. It affected many groups of organisms in many different environments, but it affected marine communities the most by far, causing the extinction of most of the marine invertebrates of the time. Some groups survived the Permian mass extinction in greatly diminished numbers, but they never again reached the ecological dominance they once had, clearing the way for another group of sea life.

Download the PDF From the time America struggled for a new identity as a constitutional republic—and well into the 20th century—its architecture and its decorative detailing remained firmly rooted in the European classicism of Palladio, Wren, and Mansart. Together with skilled masons and carpenters, ornamental plasterers saw their inherited trade flourish from the mid th century until the Depression years of the s.

During this two hundred year period, as the Georgian and Federal styles yielded to the revivals—Greek, Rococo, Gothic, Renaissance, and Spanish—decorative plaster reflected each style, resulting in the wide variety of ornamentation that survives. The traditional methods of producing and installing interior decorative plaster were brought from Europe to this country intact and its practice remains virtually unchanged to this day.

Like flat walls and ceilings, historic ornamental plaster is made of gypsum and lime which are stable and durable materials. An extremely versatile material, plaster can be modeled, cast, incised, colored, stamped, or stencilled. However, as an integral part of the building system it is subject to the typical problems of water intrusion, structural movement, vibration and insensitive alterations, both incrementally and from adaptive use projects.

Ornamental plaster studios employed a variety of personnel, including sculptors who modelled in clay; casters who made production units; and finishers who cleaned the casts. This Preservation Brief has been prepared to assist property owners, architects, contractors, and Federal agency managers in identifying the causes of ornamental plaster failure, specifying repair and replacement techniques and engaging qualified professionals to do the work. The scope of this Brief is limited to the repair and restoration of existing ornamental plaster; certain forms of decorative plaster such as scagliola, composition ornament, and artificial Caen Stone are not addressed, nor is the design and installation of ornamental plasterwork in new construction.

Finally, guidance on using substitute materials to match the historic appearance of ornamental plasterwork—a legitimate option within the Secretary of Interior’s Standards for the Treatment of Historic Properties—is not discussed here, but will be the subject of another Brief on interiors. American plaster studios employed immigrant and, later, native craftsmen. Plasterers’ guilds were in existence in Philadelphia in the s.

In , a plasterers’ union was organized in the United States with members from the British Isles whose work there had been limited to palaces and churches.

Supplies of FGD gypsum will drop dramatically in the coming years as coal-fired power stations are progressively closed, and environmental and other regulations are curtailing the supply of some sources of natural gypsum. Some bulk gypsum suppliers are curtailing exports to focus on domestic markets. Recycling is becoming a potentially significant new source of raw materials.

Bring fact-checked results to the top of your browser search. Nonradiometric dating In addition to radioactive decay , many other processes have been investigated for their potential usefulness in absolute dating. Unfortunately, they all occur at rates that lack the universal consistency of radioactive decay. Sometimes human observation can be maintained long enough to measure present rates of change, but it is not at all certain on a priori grounds whether such rates are representative of the past.

This is where radioactive methods frequently supply information that may serve to calibrate nonradioactive processes so that they become useful chronometers. Nonradioactive absolute chronometers may conveniently be classified in terms of the broad areas in which changes occur—namely, geologic and biological processes, which will be treated here. Geologic processes as absolute chronometers Weathering processes During the first third of the 20th century, several presently obsolete weathering chronometers were explored.

Most famous was the attempt to estimate the duration of Pleistocene interglacial intervals through depths of soil development. In the American Midwest, thicknesses of gumbotil and carbonate-leached zones were measured in the glacial deposits tills laid down during each of the four glacial stages. Based on a direct proportion between thickness and time, the three interglacial intervals were determined to be longer than postglacial time by factors of 3, 6, and 8.

We do not know exactly when the village was founded. Bricks discovered in the original enclosure wall were stamped with the name of Tuthmose I, although Queen Ahmose-Nefertari and her son Amenhotep I of early Dynasty XVIII were revered by the inhabitants, suggesting that its origins may have been earlier. A cult temple of Amenhotep I was situated at the northern end of the village.

Working techniques[ edit ] Alabaster is mined and then sold in blocks to alabaster workshops. The effect of heating appears to be a partial dehydration of the gypsum. If properly treated, it very closely resembles true marble and is known as “marmo di Castellina”. In this way a very misleading imitation of coral that is called “alabaster coral” is produced.

This was the case with small flasks of the alabastron type made in Cyprus from the Bronze Age into the Classical period. Calcite alabaster[ edit ] Calcite dish from the Ancient Egyptian tomb of “U”, Semerkhet Calcite alabaster, harder than the gypsum variety, was the kind primarily used in ancient Egypt and the wider Middle East but not Assyrian palace reliefs , and is also used in modern times.

It is found as either a stalagmitic deposit from the floor and walls of limestone caverns , or as a kind of travertine , similarly deposited in springs of calcareous water. Its deposition in successive layers gives rise to the banded appearance that the marble often shows on cross-section, from which its name is derived:
