whats the difference if any between the two?
TIA

Piping gel is a solution of sugar with a gelling agent cooked in, it will sit in place if piped on a flat surface.

Glucose is a dense syrup that adds invert sugar to formulas like fondant and candy. This prevents crystallization of large sugar crystals.

NOT THE SAME AT ALL.

wow! thanks - never knew the difference.

Sugar Art Tip... Footnote on piping jelly and uses:
It can be used to coat a dummy prior to covering the dummy with Pettinice.
Used for rice paper painting and in making gold and silver piping mediums.
and stained glass windows, also to create a champagne look on cake by whipping it to form bubbles.

chellescakes thanks for the receipe and the tips.
i am covering a cake dummy tonight and wanted to piping gel.
i am not aware of what pettinice is.
will this an issued when covering the dummy? i am ready to cover shortly.

Pettinice is just another name for fondant.

I just looked at the ingredients of glucose...it's just plain old LIGHT CORN SYRUP...imagine that!! 

AThat may be so, but glucose is an invert sugar and won't revert back to crytalline form and is thus much better for certain applications.
