The world of Ulli Knall is kooky and sublime; her enigmatic ceramic figures freeze moments in time where humans, animals and aliens create speculative relationships and hybrids find happiness in each other’s forms.
Jes Fernie, April 2000

As reverential busts deposited in kitsch costumes with earnest intentions, Ulli Knall’s sculptural imagery lacks any retrogressive removal from the danger of life today; this is more slippery than any cosy sentimentalism.
Sally O’Reilly, LondonArt.co.uk, February 2000

The simplest way to understand the work of Ulli Knall is: try not to. When you start to get your head around Ulli’s theory, every theory on life you have falls apart - it’s disconcerting stuff.
Gemma de Cruz, Flash Art 109, March / April 2000

While Poussain was a great inspiration once, the environment is a greater influence on us all: the shape of a nose, the colour of football shirts, jewellery, navels and the soft tissue of the stomach, the smooth, cold hardness of a frozen chicken.
David Burrows, April 2000
