We need to have the information put in the standard table I think.

things that could be considered

to be included in this article are the density, viscosity, specific heat and structure data of boron trioxide.

The density given for the liquid is actually that of crystals.

In the Kirk-Othmer Encyclopedia of Chemical Technology, 4th edition, Smith, R.A. and McBroom, R.B. discuss the vitreous form's density thus,

... At 0.28 wt % of water the density of boric oxide is 1.853, softening point 240-275°C; nearly anhydrous B2O3, having 20 ppm water has density 1.829 g/ml and a softening point of 300-325°C ...

and the abstract of "High-Temperature Density Determination of Boron Oxide and Binary Rubidium and Cesium Borates" gives this rule,

The density of B2O3 can be represented between 600° and 1000°C as d = 1.3388 + 228 (1/T) and for temperatures above 1000°C as d = 1.3947 + 157.9 (1/T), where d is in grams per milliliter and T is in °K.
