The GH21 is our second most popular glory hole model, second only to the GH15/16, probably due to the fact that they are often ordered together as a pair. The GH21 is great for large pieces, especially “leggy” sculptural forms. See table below for details and prices.
Options include Combustion System with Variable Speed Blower, NFPA 86 Safety System and Automatic Temperature Control. See Glory Hole Combustion and Safety Packages link below for details. Contact us for current pricing.
