What kind of casting method is resin casting?
Resin casting is done by use of a mold and a mixture made with a form of liquid synthetic resin. It is then poured or injected into the mold and left to sit until hardened.
What is urea resin adhesive?
It's a form of powdered urea, that when mixed with water, becomes a wood glue.
How did amber form?
Amber is formed from the resin of ancient trees that becomes fossilized over millions of years. When a tree is injured or stressed, it produces resin to seal the wound, and this resin can eventually harden and solidify into amber through a process involving heat, pressure, and time.
Can you use a glass mold when casting clear polypropylene resin or will it bond with the glass?
You do not want to use a glass mold when casting resin. Resin is a two-part compound that, when mixed in proper proportions, becomes completely hard when dry. When casting resin, you want to use a flexible mold, such as a silicone mold, to cast it. Once the resin has hardened, you can flex a silicone or rubber mold, stretching and bending it to allow air between the mold and the shape, which allows the mold to release the resin form. The mold will revert back to its original state after the form has been released. A glass mold has no flexibility. If you cast resin in a glass mold, the resin will harden exactly the size of the cavity in your glass mold. While it will not bond to the glass, the result is the same. Once the resin is hard, there will be no way for air to come between the resin form and the glass mold. The resin will essentially be vacuum-sealed in place. If you have a more complex form, such as a rose shape, the resin will be stuck in place permanently. A more simple shape, such as a square, might release over time. If you set the mold upside-down, a combination of gravity, and the effects of temperature and humidity on the glass and resin, may release the resin after many weeks or months. If you have already cast your resin into the glass mold, your only option will be to wait to see if the cast will eventually release, or carefully break the glass mold from around the resin.
How can imprints form a fossil?
It takes several millions of years for a fossil to be created. First an animal may step in mud whichs dries over time and becomes hard. After it has that mold the conditions have to be right for it to form. If they are then it will form.
What is resin clay?
Resin clay is clay that is resin-like. It tends to have resin-like features once dry and comes in a clay form. It comes in several brands, all of them in clay form, and all dry to a resin finish.
What type of plastic does not melt?
Thermosetting plastics. Once cooled and hardened, these plastics retain their shapes and cannot return to their original form. Thermosetting plastics dont melt (i think) :)
Plants hardened over thousands of years forming which is one of your energy sources today?
Fossil fuels, such as coal, oil, and natural gas, were formed over thousands of years from the remains of plants and other organisms. When these fossil fuels are burned, they release stored energy in the form of heat, which is used for electricity generation, transportation, and heating.
How is a fossil created?
Fossils are created by the mineralization of the remains of dead organisms, especially their skeletons. Sometimes there are fossil imprints where remains were pressed into rock, ash, or sediment that later hardened. More rarely, an animal part decomposes and the space is filled to form a cast impression. (see the related link)
Does hardened lava form a vent?
No, it forms a volcano.
Is ceramic a textile?
