What temperature do you need to set the oven so that acrylic softens?

You should not attempt to soften acrylic in an oven.

Here's why:

* Acrylic is flammable: Heating acrylic to a high temperature can cause it to ignite. This is extremely dangerous.

* Acrylic releases harmful fumes: When heated, acrylic releases toxic fumes that can be harmful to your health.

* Acrylic deforms unpredictably: Acrylic doesn't soften in the way that other materials do. It's more likely to warp, melt unevenly, or become brittle.

Safe Alternatives for Working with Acrylic:

* Heat gun: A heat gun can be used to gently warm small areas of acrylic, making it more pliable for bending or shaping.

* Acrylic solvent: Certain solvents can be used to dissolve acrylic, allowing you to reshape or repair it.

* Professional heat bending: For larger or more complex projects, consider having a professional heat bend your acrylic.

Remember: Always prioritize safety and follow the manufacturer's instructions for working with acrylic.
