Direct-to-Substrate Sandcarving better with a 3-mil resist, and the heavier blasting is better with a 5-mil resist. The thicker the resist, the better it holds up to the sand and heat produced from sand- blasting. When first getting started, it is a good idea to buy a starter kit so you can test various resist thicknesses and ensure you get all the needed exposure items. If you want to do heavy carving into the glass, sandcarving vinyl is made for this. You can get thick, high-tack vinyl that allows you to carve the most aggressive designs out there. Generally, my go-to vinyl supplier is Hartco 300 series; this has worked well for glass and some stone blasting. Squeegee – This tool helps you place your resist or vinyl onto glass with mini- mal air bubbles. To use effectively, place your design onto the glass and press the resist/vinyl down from the top to the bottom in one straight line. Next, use the squeegee to work from the middle of your design to the closest edge. This forces the air out of the design and to the closest edge. By working from the middle to the edge, you avoid trap- ping the air while trying to remove it. Bubble Popper (aka Wire Wheel Brush) – This little gem is a lifesaver. When I first started out, I did not know about the wire wheel brush and constantly had issues with centers of letters blowing off when blasting. Turns out that there was a trapped air bubble that lifted the resist off the glass and allowed the centers of letters to not adhere to the glass. The wire wheel brush pops the mem- brane of the resist, removing the trapped air, and allows you to press the resist onto the glass and avoid costly ruined pieces. Two-Inch-Wide Masking Tape – This is the one supply that drives me crazy, and I can't seem to live without it. I like to use the two-inch-wide tape Seen here in action is a squeegee, a necessary tool for the sandcarving process.
