Item Name: Etch-All Dip 'n Etch Liquid - 16oz SKU: ETCHALL16OZ. Description: Etch-All Dip 'n Etch Liquid is a reusable glass etching liquid designed to create a matte, fingerprint-proof etched finish on clear or colored glass, excluding Pyrex. After etching, the newly textured surface will hold oil, acrylic paints, or inks, making it useful for both decorative and functional surface work. This product is formulated for a short working cycle, with an application time of about 15 minutes, and it can also be used to etch other hard surfaces including mirror, ceramic, porcelain, marble, slate. How it is used: This etching liquid is used when you want to take glare off a glossy surface, add a soft satin finish, or create an etched background that makes carved, sandblasted, or engraved details stand out. In lampworking and fused glass studios, it is commonly used to etch finished pieces for a more tactile grip and a more diffused, professional-looking surface, and it is also used to prep etched areas that you plan to highlight with paint or ink.
