Enter the formula and formula weight directly into the Insight MDT dialog (since it records materials as formulas).
Enter the analysis into an Insight recipe and enter the LOI using Override Calculated LOI (in the Calc menu). It will calculate the formula.

Boraq is the tradename for a material developed jointly by Digitalfire Corp. and Plainsman Clays. It is a substitute for Gerstley Borate. Digitalfire Corporation has made this recipe public and created a web site to document it. The aim of this open approach is to solicit your help to improve it and produce a Boraq 2 recipe for final production. The materials and Boraq itself are for sale at the website linked to this recipe.

Within INSIGHT you can double click any of the materials in the recipe and INSIGHT will show you their chemistry. Then click the 'More Info' button in the Materials dialog and INSIGHT will display even more information. Double-click the item in the list in the Materials dialog and you'll get even more.

We suggest you enter the Gerstley Borate and Boraq chemistries into INSIGHT and compare them. The website at www.gerstleyborate.com has a material-by-material and oxide-by-oxide analysis for the similarities and differences between boraq and gerstley borate.

You can order a sample of this material at https://digitalfire.com/plainsman/store/store.php
