我发现玻璃胶已经干了，但甲醛的释放可能还在继续。玻璃胶在固化过程中会产生刺激性气体，而干透后的甲醛释放则需要较长时间才能完全停止。一般来说，中性玻璃胶表面干燥大约需要2小时，而酸性玻璃胶则是30分钟左右。不过，完全干透所需时间更长，通常中性型号需要48小时，而酸性型号可以在24小时内完成。

使用硅酮类玻璃胶时，我们必须注意它的固化和粘接流程。在修补表面之前，必须等到外层表皮形成，这个时间因不同特性的硅酮而异，大约5-10分钟或30分钟。若使用分色纸覆盖某一区域，则必须在外皮形成前取走。

Glassware adhesion process is a complex one. First, you need to clean the surface thoroughly, removing any dirt or oils. Then, apply a thin layer of glass adhesive and press the two surfaces together firmly until all air bubbles are removed. The adhesive will then dry and harden over time.

It's important to note that different types of glass adhesives have different drying times and curing times. For example, acid-based adhesives typically dry faster than neutral ones. Additionally, the thickness of the adhesive layer can affect how long it takes for it to fully cure.

In summary, even though the glass has dried on its surface, there may still be some residual fumes from the adhesive that could pose health risks if inhaled. It's important to follow proper ventilation procedures when working with these materials and avoid inhaling any fumes that might be present.

Here are some tips for working safely with glass adhesives:

Always wear protective gear like gloves and goggles when handling these chemicals.

Make sure your workspace is well-ventilated by opening windows or using fans.

Avoid inhaling fumes directly from the bottle or container.

Use a fan or blower to blow away any fumes that might accumulate near your work area.

If you experience any irritation or discomfort while working with these materials, stop immediately and consult a medical professional.

By following these simple precautions, you can ensure a safe and successful project without putting yourself at risk of exposure to harmful chemicals like acetone or solvents found in many household cleaners."
