Adhesives, excipients and solvents are included in the composition of the glues. Glues, glue sticks, tapes, etc. in office supplies are used to affix various papers. Because of their low frequency of use, it is often easy for people to ignore possible safety problems. In particular, the quality of the glue used by students will directly affect the child's growth and health. In order to pursue low cost, some merchants may use a water-soluble polymer polyvinyl alcohol (PVA) as an adhesive, and in the process of making a solid glue, PVA can only be produced by using formaldehyde. When using this product, the presence of formaldehyde directly harms human health.

Techniques for glue & glue sticks testing
Viscometer
Used to measure the viscosity of adhesives, assessing their flowability and applicability. Common types of viscometers include rotational viscometers, falling ball viscometers, and electronic tensile viscometers.
Hardness Tester
Used to measure the hardness of cured adhesives, such as Durometer hardness testers and Rockwell hardness testers.
Tensile Testing Machine
Used to test the tensile strength and elongation at break of adhesives.
Thermal Analyzer
Used to analyze the thermal stability and composition of adhesives, such as Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC).
Microscope
Used to observe the microscopic structure and bonding interface of adhesives.
UV-Vis Spectrophotometer
Used to analyze the chemical composition of adhesives.
Infrared Spectrometer
Used to analyze the chemical composition and thermal stability of adhesives.
Peel Strength Tester
Used to test the adhesive strength of adhesives on different material surfaces.
Aging Test Chamber
Used to simulate the aging of adhesives under different environmental conditions.

Determination of Heavy Metals in Polyvinyl Acetate-Based Glue by ICP OES
Matoso, Erika, and Solange Cadore. Talanta 84.2 (2011): 335-340.
A closed vessel microwave-assisted method has been developed for the determination of trace metals in polyvinyl acetate-based glue, commonly used in water emulsions. The study employed Inductively Coupled Argon Plasma Optical Emission Spectrometry (ICP OES) to analyze elements such as As, B, Ba, Bi, Cd, Cr, Cu, Fe, Hg, Ni, Pb, Se, Sn, and Sb. Optimization of parameters, including wavelength, nebulization pressure, and RF power, led to satisfactory results with detection and quantification limits, achieving recoveries ranging from 80–106% for most analytes.
The analysis revealed that the concentrations of most metals in colored glue samples (white, black, blue, yellow, red, and green) were below the limit of quantification (LOQ), with the exception of Fe, Cu, and Cr. Nickel concentrations were near the LOQ in white glue but detectable. These results were compared with regulatory limits, confirming that the levels of metals in the samples were not harmful. The study indicates that colored glue does not pose a health risk, aligning with regulatory standards and validating the microwave digestion and ICP OES method for effective environmental and health safety testing.
