Safety glasses at e a must in the shop. Get good ones because it is pretty stupid to try and save a buck or two when talking about your eyesight. UV lenses are a good idea. If doing a lot of forging and oven work, a second pair of kiln glasses are useful. The Auralens AUR-99 lenses do well for our use, and are affordable. They also come in may prescription and IIRC, bifocals.
Most knife suppliers carry the insulating kiln gloves. They are often called HT gloves. The wrist length ones are OK for straightening hot blades and other forge work, but the longer gauntlet ones are best for taking things out of a hot kiln. The rush of hot air can singe and burn things a good foot or more away from the door. If you have a bushy beard, be aware of this!
