Abstract

The present invention provides a paste-like dental glass composition having good ease of handling due to a reduction in paste runniness while enabling accurate shade adjustments with no discoloration to hues such as black or grey after firing. The present invention relates to a paste-like dental glass composition comprising a glass powder (A), and an organic solvent (B) having two or less hydroxyl groups within the molecule and a viscosity at 20° C. of 2,500 mPa·s or less, and being essentially free of an organic compound having three or more hydroxyl groups within the molecule.
