Can you cast pewter into plaster of Paris?
Yes, but the method for making sure the material separates from the plaster mould is quite involved. Some mould makers use shellac, followed by a soap treatment. There are several steps to the process, and you will probably have to destroy the mould as you break the positive out. For detailed steps on how to do this, research "plaster waste moulds"
Can you fire plaster in a kiln?
Brass does not fire... it melts. Whether brass can survive a kiln firing depends on the temperature you are firing to... Brass melts above 900 C. It get REALLY soft above 700C Kilns can fire much higher than that. So, its not a good idea This is a correction to the previous answer. Many kilns are programmable. While these kilns have a max temp, you can go as low as you want. So you can easily program a kiln to heat at 900C.
Is a volcano stronger than an earthquake?
it depends how strong the earthquake is some can be stronger than a volcano or than a volcano can be really strong
How does an artist make a fresco?
Frescoes were made by painting waterbased paint on fresh plaster. This caused the paint to sink into the plaster, thus making it much more permanent than painting on a dried surface. Leonardo da Vinci's famous Last Supper is a fresco and even though it is damaged, it still has lasted over 400 years.
What city has the most restaurants?
If you mean in the usa it would be NYC. If you mean outside of the usa it would be Paris. Paris has more resturants than NYC.
Does gypsum react the same way as plaster of Paris?
Yes, gypsum and Plaster of Paris (POP) are closely related. POP is actually made by heating gypsum, so their chemical reactions are similar when mixed with water—they both harden quickly and are used for wall and ceiling finishes. But in real usage, gypsum plaster is better than regular POP. It’s stronger, more crack-resistant, and doesn’t shrink much after drying. I’ve used Buildwell gypsum plaster for ceiling work and it gave a smooth, long-lasting finish—much better than local POP brands. It’s one of the best gypsum plaster products in India.

Why is Portland cement stronger than Plaster of Paris?
Portland cement is stronger than Plaster of Paris primarily due to its composition and hydration process. Portland cement contains a mixture of calcium silicates and other compounds that, when mixed with water, undergo a chemical reaction called hydration, resulting in a dense and durable structure. In contrast, Plaster of Paris is made from gypsum, which hydrates to form a softer, less dense material that is more suitable for decorative applications rather than load-bearing uses. Additionally, Portland cement has a higher compressive strength, making it ideal for construction purposes.
What happens when water is added to plaster of Paris?
well it probably forms plaster.A2. Plaster of Paris as usually bought has been dried - the water of crystallization has been removed.When you re-hydrate the material, the molecules are able to take up this water, and form new inter-locking crystals. This we recognize as a solid.When it is applied as a plaster cast to immobilize a broken joint, usually more water is used (to aid working) than is need for the setting process. This water evaporates slowly, but cools the limb due to evaporative cooling.
How do you dissolve plaster of Paris?
"I think vinegar is supposed to work.Lawren1The CRC Handbook of Chemistry and Physics (65th ed. Special:Booksources) lists plaster of Paris (calcium sulphate half-hydrate, CaS04.1/2H2O) as soluble in acid, ammonium salts, sodium thiosulphate (Na2S2O3) and glycerin."I am so surprised that so many people on so many forums, obviously don't have a clue about the chemistry of plaster of Paris. I read in so many places things like "uh, try some kind of acid..."So I have a lot of concentrated chemicals on hand and did lots of experiments with all kinds of acids, both dilute and concentrate, under many conditions and determined that none of my dozen or so acids dissolve Plaster of Paris in any way, but sometimes make it harder.The chemicals which dissolved plaster of Paris are on the basic end of the PH scale, not acid. I first had some success with potassium cyanide, but what really worked better than anything is Sodium Bicarbonate. Makes sense. The sodium in baking soda hooks up with sulfur in the plaster, and the carbon hooks up with the calcium in the plaster.TO BEST DISSOLVE PLASTER OF PARIS PLACE IT IN WARM WATER WITH LOTS OF BAKING SODA.Don't use any acids or it will only defeat the process.Now what really amazes me is that the answer is so simple and safe, and surely some people must know it, but it apparently cannot be found on the internet, until now.Or you can chisel it away because it is soft enough to do so.
Will epoxy adhere to plaster of Paris?
yes, but it may change the color slightly. Thin with toluene or xylene preferably, if none on hand, acetone will work in a pinch. not more than 10%.

Can you put plaster of Paris models in the oven once painted to 'glaze' them?
no. the white will burn and become brown, or could start a fire!!! glaze should not be used on plaster only paint is suggested. if you want a glaze look, use polyurithane. this you can let air dry and it will be glossyANSWER:No heat required. Either use a high gloss latex paint for a glossy sheen, or use a clear spar varnish to seal and protect. It may take more than one coat as plaster of Paris is very porous.
What are the benefits of pebble tech versus Plaster?
PebbleTec lasts longer than plaster (and is usually warrantied for longer than plaster). In addition, it is darker so typically hides the staining that often comes with pool chemicals.
What is dead burnt plaster and how is it formed?
Dead burnt plaster is a type of gypsum plaster that has been heated to a high temperature, resulting in a loss of water content and converting it to anhydrous or dead burnt calcium sulfate. This process is typically carried out in a kiln or furnace at temperatures above 200°C, which removes water molecules from the gypsum and transforms it into a dry powder with different properties than regular gypsum plaster.
Does a dark-colored pool plaster hold in the heat better than a white pool plaster?
It makes very little difference

Is Paris more crowded than Istanbul?
