Adhesively bonding materials can be complex at times due to the boundary between the two materials beingjoined. Poor bonding can be caused by surface contaminations, improper installation procedures or simply notusing the right bonding product. In addition, it is possible that the type of adhesive works well for one materialbut may not be as effective for a different material.The objective of this study will determine if one adhesive can work well for all types of crystal jewelrysubmitted to different scenarios and if a unique preparation process for the crystals and adhesives are required.The research supported by this NSERC Engage Grant will investigate the use of a variety of commerciallyavailable adhesives on four crystal types. The adhesive bond strength will be evaluated under differentconditions such as: contaminates on the as-received crystal surfaces, epoxy-clay adhesive mixing time, workingtimes and curing temperature. The bonded crystals will also be subjected to temperature fluctuations (+35°C to-35°C) to reproduce real world applications and their bond strength assessed. By employing an optimizationtechnique, the best formulation will be determined for the best bond strength.The performance of the selected adhesives will enable recommendations to be made related to their adhesionability and crystal surface preparation technique. It is anticipated the research will provide a faster, morereliable assembling technique than the previous approach. An innovative, unique step-by-stepsolution/procedure to provide a high strength bond between jewelry and epoxy-clay adhesives will be provided.

由于两种材料之间的边界，粘合材料有时可能很复杂，表面污染、安装程序不当或未使用正确的粘合产品也可能导致粘合不良。对于一种材料效果很好，但对于另一种材料可能效果不佳。本研究的目的将确定一种粘合剂是否可以很好地适用于不同情况下的所有类型的水晶首饰，以及水晶和粘合剂的独特制备工艺是否适用这项 NSERC Engage Grant 资助的研究将在四种晶体类型上使用各种市售粘合剂，并在不同条件下进行评估，例如：原始晶体表面上的污染物、环氧树脂。粘土粘合剂的混合时间、工作时间和固化温度也会受到温度波动（+35°C 至 -35°C）的影响，以重现实际应用并评估其粘合强度。通过优化技术，将确定最佳配方以获得最佳粘合强度。所选粘合剂的性能将有助于就其粘合性和晶体表面制备提出建议，预计该研究将提供更快、更可靠的组装。将提供一种创新、独特的分步解决方案/程序，以在珠宝和环氧粘土粘合剂之间提供高强度的粘合。
