I have finally been able to create fractureless specimens in cylindrical geometries. All pictures shown on this page were produced in a 12 hour start to finish one steptechnique. My hopes are to trim the time down to under 2 hours, and increase the diameters to nearly 5 cm (currently the largest fractureless cylinder that I have succesfully made is 15mm diameters)

 

    
     

Shown above is a base catalyzed TMOS speciman

Specimens are very transparent and appear to have low index of refraction. Blueish tinit is noticeable when infront of black surface, specimens have yellowish tint when held up to light source

 

  
     
  This batch had consistant densities of .298 g/cm^3   Shrinkage from original liquid reactant filled molds. Linear shrinkage of about 30%
