Kremer states bloomgrams in their material data sheets. I have emailed Dictum some years ago asking for their glue´s strength, i´m presuming its still the same.
Apart from precise definitions, which are a google click away, the most obvious difference (for me) is working time. I don´t have much to compare - only hide from Kremer and Dictum and bone. Dictum´s higher bloomgram stuff needs more water to get it to the consistency i like (between 1,8 and 2,0 times the amount of water, depending on its intended application), while with kremer´s glue i usually use between 1,5 and 1,7. The consistency is about the same but Kremer´s stuff gels slower and i tend to use it for larger surfaces such as scarf joints, headplates and such. I prefer Dictum´s for brace gluing, dentellones, joining tops and backs, etc. I guess i´m spoiled for choice.
Dictum´s current batch of hide glue is good stuff, you should try it. It´s in granulate form (much quicker at soaking water), light in color and doesn´t smell that strong. Over the years i kind of developed a taste for the smell, actually - if i may disclosure such personal stuff here.
Now Kremer´s. A couple of years back i bought some of their cubes and really liked it. Different smell (maybe easier on the palate), light in color and longer open time, as i´ve said. I believe it was their catalogue number 63010. So i ordered 3 kgs last time and got a very different stuff. Similar smell, but darker, needs only 1,2 times the amount of water to get to the same consistency (which sounds suspiciously low) and takes ages to gel. Glue tests still got wood failure but i´m wary of using the stuff.
May i ask you how´s your batch of Kremer´s glue? (and sorry for the long post)
