46 • A&E FEBRUARY 2019 the design; fine details will be lost, and the resist will start to separate and break down." —Braden Todd, Glassmith2 What are some general artwork consider- ations to keep in mind for sandcarving projects? "Bold, open, sans serif fonts work best for deep etching, and if at all possible, avoid small script fonts. We recommend text being 8 points or larger, but it all depends on the font your customers choose. The larger the font, the clearer the text will be. We've also found that positive artwork should be a minimum of .75 points thick in order to etch well, while negative art- work should be a minimum of 1.5 points thick. Sharp points should also be blunted, rounded, or thickened." —Jen Jezierski, Crystal D "Vector images are required to process photoresist stencil. Black-and-white art- work, no-color images are required. For vector files, keep to the following formats: AI, CDR, PDF, EPS, and lastly TIFF." —Liz Haas, Rayzist Can you list some popular substrates for sandcarving? "Sandcarving offers entrance into numerous markets including awards and gifts, collectibles, memorial items, promo- tional products, and signage. One can carve on flat and curved substrates. Brittle mate- rials such as glass, crystal, stone, ceramic, marble, granite, and wood are perfect sub- strates for deep sandcarved designs. Metal, plastic, acrylic, and any other less brittle materials are ideal for surface etching rather than a deep carve." —Michael Sullivan, IKONICS Imaging "(Optical crystal) has a higher perceived value for awards because it looks so much more expensive than it actually is. When you etch a message of appreciation on a beautiful optical crystal award, you're helping your customers create a lasting memory." —Jen Jezierski, Crystal D What are the proper settings and proce- dures to follow when sandcarving glass? "Start with your design. If you have a lot of small details or thin lines, you will not want to blast too deeply. Some designs do not look good with a deep blast. If you're blasting a rectangle with text in the middle on the back of glass, the depth of the rect- angle can make the text harder to read and not as clean as a shallower blast. Proper settings do vary by substrate and design. If you're unsure, start with a lower psi and work your way up. Always watch your blasting angle, how you hold your item, and the speed you blast at. To have consistent sandcarving, your technique needs to be consistent as well." —Braden Todd, Glassmith2 "Glass and optic crystal scratches easily, so use caution when handling glass. Use a low-tack transfer tape or cling plastic wrap to protect the back of the glass from scratching during handling." —Liz Haas, Rayzist "Grit size and type are important when sandcarving glass. For best all-around results, silicon carbide grit in a 180 mesh size is recommended. To do fine detail, and for shading purposes, 220 mesh or finer works well. Other abrasives (such as aluminum oxide) can also be used. With all photoresist films, establish the correct exposure time for your particular exposure unit and follow the film instructions.
