Abstract Matching a porcelain restoration is a difficult task for both the dentist and the dental technician. In order to improve communication, it was suggested that a new previsualization technique with a new modeling liquid could be introduced. This study investigates the effect of this modeling liquid on color, translucency, and biaxial flexure strength on different types of veneering porcelain. A total of 42 samples were tested for IPS e.max veneered discs, feldspathic discs and the porcelain fused to metal discs. Twenty‐one were prepared with the manufacture liquid, while the other 21 were prepared with Visual‐Eyes modeling liquid. The porcelain powder was prepared for the Visual‐Eyes liquid by removing the food dyes with a specific firing cycle recommended by the manufacture. The porcelain mixes were layered using standardized Teflon molds of different thicknesses. The color and translucency and the biaxial flexure strength were tested. The results revealed statistical significance in the translucency between the liquids in all types of veneering porcelain. The manufacturer's liquid showed higher translucency than Visual‐Eyes liquid; however, the color difference and the biaxial flexure strength were similar between the two liquids. The use of the Visual‐Eyes liquid is indicated in specific cases of complicated build‐ups. This study has targeted a material that has never been investigated before. The material was invented several years ago and updated to the new liquid, but its effect on porcelain is still unknown.
