Abstract
We argue that there are generic solutions to the type 0 gravity equations o f motion that are confining in the infrared and have log scaling in the ult raviolet. The background curvature generically diverges in the IR. Neverthe less, there exist solutions where higher order string corrections appear to be exponentially suppressed in the IR with respect to the leading type 0 g ravity terms. For these solutions the tachyon flows to a fixed value. We sh ow that the generic solutions lead to a long range linear quark potential, magnetic screening and a discrete glueball spectrum. We also estimate some WKB glueball mass ratios and compare them to ratios found using finite temp erature models and lattice computations.
