Temporary mounts are usually made in aqueous solution, that is, in water or buffer. They aren't meant to be kept for more than a few hours, since tissue degradation can set in soon. Permanent mounts, on the other hand, usually involve resin to seal them onto the slide and make them waterproof. Since it can't come in contact with external elements that can degrade it, permanent mounts last longer, and can be visualized even after months, or years, depending on the mountant used.
A temporary mount is created by placing a specimen on a slide without using any mounting medium, while a permanent slide involves using a mounting medium (such as Canada balsam) to affix the specimen to the slide permanently. Permanent slides are more durable and suitable for long-term storage or examination, while temporary mounts are often used for quick observations or educational purposes.
