Drying Chemically Treated Scarlet Oak and White Oak Lumber

Although results of study are inconclusive, they indicate that chemical treatment with Morton Lumber Cure (a buffered salt, consisting essentially of sodium chloride and some undisclosed corrosion inhibiting additives) can help to minimize honeycomb degrade when high temperatures (180?F.) and rapid drying schedules (8-10 days) are used. Specific results showed that 1) White oak (Quercus alba L.) honeycombs considerably less than scarlet oak (Quercus coccinea Muenchh) lumber when dried under the same high-temperature conditions, whether treated or not treated with a sodium chloride base chemical. 2) Green 1-inch white oak can be dried in 8-10 days with a limited amount of degrade by using rapid kiln-drying schedule and Morton Lumber Cure applied to the lumber dry. 3) Dipping lumber in a 25 percent solution of the chemical was ineffective in reducing honeycomb under high temperatures. 4) Damage from honeycombing in scarlet oak was reduced considerably when lumber was bulk piled. The drying schedules used in study were considered still too severe for scarlet oak. 5) While results of test methods show a considerable reduction in percentage of honeycombing when comparing treated and untreated specimens, only about 50 percent of treated boards were free of honeycombing. This and the corrosion problem probably make the method still unacceptable commercially.
