How to recover when liquid glue solidifies and dries?

Liquid glue can be cured by adding the original solvent of glue. Long-term stirring may have certain effect, but it is far from being useful before curing, because some polymers are irreversible and may not be recycled, although the probability is relatively small.

The glue in the glue bottle will not stick and solidify, because the bottle cap prevents the solvent from evaporating. If you open the bottle cap, it won't be long before the glue is only sticky, so it won't be easy to pour out at this time.

Precautions for using liquid glue:

Liquid glue will release irritating gas during the curing process, which will stimulate people's eyes and respiratory tract. Alcohol-based neutral glue will release methanol during curing.

Methanol is potentially carcinogenic and is a known skin and respiratory allergy. Volatile gases can cause inflammation of the eyes, nose and throat. Therefore, this product should be used in a well-ventilated environment to avoid long-term contact with eyes or skin, and do not swallow this product.
