Popis: | This study has shown that high-altitude boiling of reversible hydrocolloid in water alone is inadequate. It must be liquefied at a temperature of at least 100 degrees C. (212 degrees F). The use of propylene glycol alone in the liquefying bath or as an additive to water is effective in attaining this temperature. A microwave oven did not liquefy the reversible hydrocolloid adequately. |
